Preface Regardless of background or major, students will see their world reflected in Social Psychology

Students will see themselves, their families, or

their workplaces within the pages of this text.

In barely a century of formal study, significant

insight has been gained into belief and illusion,

love and hate, conformity and independence—

social behaviors that we encounter virtually every

day in all walks of life. In these pages students

will see themselves and the world in which they

live and love, work and play.

Like the study of Social Psychology, I continue to envision this text as solidly scientific and warmly human, factually rigorous and intellectually provocative. In this edition, social phenomena that are important and relevant to today’s students are revealed throughout the narrative, and in enriching elements such as margin notes and chapter-ending Postscripts.

Understanding that students majoring in psychology, business, law, teaching, or many other areas may be drawn to the study of Social Psychology, this text is written in the intellectual tradition of the liberal arts. As with great literature, philosophy, and science, liberal arts education seeks to expand our thinking and awareness beyond the confines of the present. By focusing on humanly significant issues I offer the core content in ways that appeal to, and draw on applications from, a wide array of behaviors and experiences.

Social Psychology can now offer partial answers to many questions we face in our homes, communities, and societies:

■ How does our thinking—both conscious and unconscious— drive our behavior?

■ What leads people sometimes to hurt and sometimes to help one another?

■ What kindles social conflict, and how can we transform closed fists into helping hands?

Rev.Confirming Pages

We humans love to feel good about ourselves, and gen- erally we do. Not only are we prone to self-serving bias (Chapter 2), we also exhibit what Brett Pelham, Matthew Mirenberg, and John Jones (2002) call implicit egotism: We like what we associate with ourselves.

That includes the letters of our name, but also the people, places, and things that we unconsciously con- nect with ourselves (Jones & others, 2002; Koole & others, 2001). If a stranger’s or politician’s face is morphed to include features of our own, we like the new face better (Bailenson & others, 2009; DeBruine, 2004). We are also more attracted to people whose arbitrary experimental code number resembles our birth date, and we are even disproportionately likely to marry someone whose first or last name resembles our own, such as by starting with the same letter (Jones & others, 2004).

Such preferences appear to subtly influence other major life decisions as well, including our locations and careers, report Pelham and his colleagues. Philadelphia, being larger than Jacksonville, has 2.2 times as many men named Jack. But it has 10.4 times as many people named Philip. Likewise, Virginia Beach has a dispropor- tionate number of people named Virginia.

Does this merely reflect the influence of one’s place when naming one’s baby? Are people in Georgia, for example, more likely to name their babies George or Georgia? That may be so, but it doesn’t explain why states tend to have a relative excess of people whose last names are similar to the state names. California, for example, has a disproportionate number of people whose names begin with Cali (as in Califano). Likewise, major Canadian cities tend to have larger-than-expected

numbers of people whose last names overlap with the city names. Toronto has a marked excess of people whose names begin with Tor.

Moreover, women named “Georgia” are dispropor- tionately likely to move to Georgia, as do Virginias to Virginia. Such mobility could help explain why St. Louis has a 49 percent excess (relative to the national propor- tion) of men named Louis, and why people named Hill, Park, Beach, Lake, or Rock are disproportionately likely to live in cities with names (such as Park City) that include their names. “People are attracted to places that resem- ble their names,” surmise Pelham, Mirenberg, and Jones.

Weirder yet—I am not making this up—people seem to prefer careers related to their names. Across the United States, Jerry, Dennis, and Walter are equally pop- ular names (0.42 percent of people carry each of these names). Yet America’s dentists are almost twice as likely to be named Dennis as Jerry or Walter. There also are 2.5 times as many dentists named Denise as there are with the equally popular name Beverly or Tammy. People named George or Geoffrey are overrepresented among geoscientists (geologists, geophysicists, and geochem- ists). And in the 2000 presidential campaign, people with last names beginning with B and G were disproportion- ately likely to contribute to the campaigns of Bush and Gore, respectively.

Reading about implicit egotism–based preferences gives me pause: Has this anything to do with why I enjoyed that trip to Fort Myers? Why I’ve written about moods, the media, and marriage? Why I collaborated with Professor Murdoch? If so, does this also explain why it was Suzie who sold seashells by the seashore?

Liking Things Associated with Oneself focus

prefer not only letters from their names but also numbers corresponding to their birth dates. This “name letter effect” reflects more than mere exposure, however— see “ Focus On: Liking Things Associated with Oneself .”

The mere-exposure effect violates the commonsense prediction of boredom— decreased interest—regarding repeatedly heard music or tasted foods (Kahneman & Snell, 1992). Unless the repetitions are incessant (“Even the best song becomes tiresome if heard too often,” says a Korean proverb), familiarity usually doesn’t breed contempt, it increases liking. When completed in 1889, the Eiffel Tower in Paris was mocked as grotesque (Harrison, 1977). Today it is the beloved symbol of Paris.

So, do visitors to the Louvre in Paris really adore the Mona Lisa for the artistry it displays, or are they simply delighted to find a familiar face? It might be both: To know her is to like her. Eddie Harmon-Jones and John Allen (2001) explored this phenomenon experimentally. When they showed people a woman’s face, their

How much do you like your name? In six studies, Jochen Gebauer and his colleagues (2008) report that liking of one’s own name is a reliable indicator of both implicit and explicit self-esteem.

Engaging research reflects students’ interests and their environment

As we see in the research literature as

well as popular blogs (and, more recently,

“tweets”), social psychology remains a compelling and dynamic area of study.

Readers of this text from around the world have reached out to me, affirming that

this richness is captured in the narrative as well as hallmark features in each chapter.

In addition to part openers, chapter outlines, and summaries, each chapter includes

the following features.

The Inside Story essays capture compel- ling stories of famous researchers in their own words, highlighting the interests and questions that guided—and sometimes misguided—their findings. For example, Chapter 4 offers an essay by Mahzarin R. Banaji on her journey from being a secretarial assistant in India to being a Harvard professor.

Focus On features give students an in-depth explora- tion of a topic presented in the text. The “Focus On” in Chapter 11, for example, describes what Brett Pelham and colleagues call implicit egotism, which is the pre- disposition that we like what we associate ourselves with.

126 Part One Social Thinking

hope, can reveal enough of a microsmile or a microfrown to indicate the partici- pant’s attitude about a given statement. A newer and widely used attitude measure, the implicit association test (IAT), uses reaction times to measure how quickly people associate concepts (Greenwald & others, 2002, 2003). One can, for example, measure implicit racial attitudes by assessing whether White people take longer to associate positive words with Black than with White faces. Across 126 studies, implicit associations measured by the IAT have correlated, on average, a modest .24 with explicit self-reported attitudes (Hofmann & others, 2005). (See “The Inside Story: Mahzarin R. Banaji on Discover- ing Experimental Social Psychology.”) A review of more than 100 studies and of more than 2.5 million IATs completed online reveals that explicit (self-report) and implicit attitudes both help predict peo- ple’s behaviors and judgments (Greenwald & others, 2008; Nosek & others, 2007). Thus, explicit and implicit attitudes may together predict behavior better than either alone (Spence & Townsend, 2007). For attitudes formed early in life, such as racial and gender attitudes, implicit and explicit attitudes frequently diverge, with implicit attitudes often being the bet- ter predictor of behavior. For example, implicit racial attitudes have successfully predicted interracial roommate relationships (Towles-Schwen & Fazio, 2006). For other attitudes, such as those related to consumer behavior and support for politi- cal candidates, explicit self-reports are the better predictor.

implicit association test (IAT) A computer-driven assessment of implicit attitudes. The test uses reaction times to measure people’s automatic

associations between attitude objects and evaluative words. Easier pairings (and faster responses) are taken to indicate stronger unconscious associations.

Mahzarin R. Banaji on Discovering Experimental Social Psychology Graduating from high school in India at age 15, I had but a single goal—to leave my well-adjusted and secure fam-ily to live the patently more daring and exciting life of a secretarial assistant. Proficient at typing scores of words a minute, I looked forward to a life of independence that involved living a block away from my parents. My mother, despite not having attended college, persuaded me to try college—but only for a semester, we agreed, after which I would be free to choose my path. The end of my first semester at Nizam College came and went. Mother didn’t ask about my plans. I didn’t have to swallow and tell. Just before one holiday trip home, I bought the five volumes of the 1968 Handbook of Social Psychology for the equivalent of a dollar apiece (it seemed like a lot of book for the money). By the end of a 24-hour train ride home, I had polished off one vol-ume and knew with blunt clarity that this science, which studied social processes experimentally, was something I had to do.

Doctoral and postdoctoral fellowships enabled me to work with three remarkable people early in my career: Tony Greenwald at Ohio State, and Claude Steele and Elizabeth Loftus at the University of Washington. At Yale, while still interested in human memory researchers, I dis-covered that memories come in both explicit (conscious)

and implicit (unconscious) forms. Might this also be true of attitudes, beliefs, and values? Hesitantly, I wrote the words “Implicit Attitudes” as the title of a grant proposal, not knowing it would become such a central part of what my students and I would study for the next two decades. With Tony Greenwald and Brian Nosek, I have enjoyed an extended collaboration on implicit social cognition that few scientists are blessed with. From the hundreds of studies that have used the Implicit Association Test (implicit.harvard.edu) and the millions of tests taken, we now know that people carry knowledge (stereotypes) and feelings (attitudes) of which they are unaware, and which often contrast with their conscious expressions. We know that subcortical brain activity can be an inde-pendent marker of implicit atti-tudes, that people differ in their implicit attitudes, and that suchattitudes and stereotypes pre-dict real-life behavior. Most opti-mistically, we know that implicit attitudes, even old ones, can be modified by experience.

Postscripts are chapter-ending vignettes that engage students with thought-provoking questions and insights from the chapter. For example, Chapter 8 (“Group Influ- ence”) explores the question, “Are Groups Bad for Us?”

Research Close-Up boxes offer in-depth looks at sci- entific exploration of a fascinating variety of topics, ranging from when people yawn to how pedestrians in different cultures interact. “Research Close-Ups” provide students with a detailed, yet highly accessible understanding of how social psychologists use various research methods,

from laboratory studies, Internet experiments, and creating virtual realities to naturalistic observation and har- vesting archival data. Chapter 12’s “Research Close-up” explores the ingroup similarities and helping behaviors of individuals under certain conditions—one of many “Research Close-Up” topics that generate rich student discourse in classrooms, dorm rooms, or virtual chat rooms.

When I first set out to write this text I engaged the services of Jack Ridl, a poet in residence at Hope College. Little did I know that his guidance, my continual work- ing and re-working of the narrative, and the Liberal Arts foundation upon which it is all built, would lead to a text that continues to be so widely accepted, beyond my wildest dreams. Whether the Internet promotes or hinders social interaction may still be debat- able (see the “Focus On” in Chapter 11!), but it has allowed me to enjoy messages from students around the globe, many expressing genuine surprise at their enjoy- ment in reading a textbook!

Helping Chapter 12 467

Ingroup Similarity and Helping

Likeness breeds liking, and liking elicits helping. So, do people offer more help to others who display similarities to themselves? To explore the similarity-helping relationship, Mark Levine, Amy Prosser, and David Evans at Lancaster University joined with Stephen Reicher at St. Andrews University (2005) to study the behavior of some Lancaster students who earlier had identified themselves as fans of the nearby Manchester United soccer football team. Tak- ing their cue from John Darley and Daniel Batson’s (1973) famous Good Samaritan experiment, they directed each newly arrived participant to the laboratory in an adja- cent building. En route, a confederate jogger—wearing a shirt from either Manchester United or rival Liverpool— seemingly slipped on a grass bank just in front of them, grasped his ankle, and groaned in apparent pain. As Figure 12.8 shows, the Manchester fans routinely paused to offer help to their fellow Manchester supporter but usually did not offer such help to a supposed Liverpool supporter.

But, the researchers wondered, what if we remind Manchester fans of the identity they share with Liverpool supporters—as football fans rather than as detractors

who scorn football fans as violent hooligans? So they repeated the experiment, but with one difference: Before participants witnessed the jogger’s fall, the researcher explained that the study concerned the positive aspects of being a football fan. Given that only a small minority of fans are troublemakers, this research aimed to explore what fans get out of their love for “the beautiful game.” Now a jogger wearing a football club shirt, whether for Manchester or Liverpool, became one of “us fans.” And as Figure 12.9 shows, the grimacing jogger was helped regardless of which team he supported—and more so than if wearing a plain shirt.

The principle in the two cases is the same, notes the Lancaster research team: People are predisposed to help their fellow group members, whether those are defined more narrowly (as “us Manchester fans”) or more inclu- sively (as “us football fans”). If even rival fans can be per- suaded to help one another if they think about what unites them, then surely other antagonists can as well. One way to increase people’s willingness to help others is to promote social identities that are inclusive rather than exclusive.

• Some studies found a same-race bias (Benson & others, 1976; Clark, 1974; Franklin, 1974; Gaertner, 1973; Gaertner & Bickman, 1971; Sissons, 1981).

• Others found no bias (Gaertner, 1975; Lerner & Frank, 1974; Wilson & Donnerstein, 1979; Wispe & Freshley, 1971).

• Still others—especially those involving face-to-face situations—found a bias toward helping those of a different race (Dutton, 1971, 1973; Dutton & Lake, 1973; Katz & others, 1975).

304 Part Two Social Influence

When an apt combination of intelligence, skill, determination, self-confidence, and social charisma meets a rare opportunity, the result is sometimes a championship, a Nobel Prize, or a social revolution.

Summing Up: The Influence of the Minority: How Do Individuals Influence the Group? • Although a majority opinion often prevails, some-

times a minority can influence and even overturn a majority position. Even if the majority does not adopt the minority’s views, the minority’s speak- ing up can increase the majority’s self-doubts and prompt it to consider other alternatives, often lead- ing to better, more creative decisions.

• In experiments, a minority is most influential when it is consistent and persistent in its views, when its

actions convey self-confidence, and after it begins to elicit some defections from the majority.

• Through their task and social leadership, formal and informal group leaders exert disproportion- ate influence. Those who consistently press toward their goals and exude a self-confident charisma often engender trust and inspire others to follow.

POSTSCRIPT: Are Groups Bad for Us?

A selective reading of this chapter could, I must admit, leave readers with the impression that, on balance, groups are bad. In groups we become more aroused, more stressed, more tense, more error-prone on complex tasks. Submerged in a group that gives us anonymity, we have a tendency to loaf or have our worst impulses unleashed by deindividuation. Police brutality, lynchings, gang destruc- tion, and terrorism are all group phenomena. Discussion in groups often polarizes our views, enhancing mutual racism or hostility. It may also suppress dissent, cre- ating a homogenized groupthink that produces disastrous decisions. No wonder we celebrate those individuals—minorities of one—who, alone against a group, have stood up for truth and justice. Groups, it seems, are ba-a-a-d.

All that is true, but it’s only half the truth. The other half is that, as social ani- mals, we are group-dwelling creatures. Like our distant ancestors, we depend on one another for sustenance, support, and security. Moreover, when our individual tendencies are positive, group interaction accentuates our best. In groups, runners run faster, audiences laugh louder, and givers become more generous. In self-help groups, people strengthen their resolve to stop drinking, lose weight, and study harder. In kindred-spirited groups, people expand their spiritual consciousness. “A devout communing on spiritual things sometimes greatly helps the health of the soul,” observed fifteenth-century cleric Thomas à Kempis, especially when people of faith “meet and speak and commune together.”

Depending on which tendency a group is magnifying or disinhibiting, groups can be very, very bad or very, very good. So we had best choose our groups wisely and intentionally.

Making the Social Connection In this chapter we discussed group polarization and whether groups intensify opinions. This phenomenon will also be covered in Chapter 15

when we look at juries and how they make decisions. Can you think of other situa- tions where group polarization might be in effect? Go to the Online Learning Cen- ter for this book to view a clip about cliques and the influence of the group.

Although only one person’s name appears on this book’s cover, the truth is that a whole community of scholars has invested itself in it. Although none of these people should be held responsible for what I have written—nor do any of them fully agree with everything said—their suggestions made this a better book than it could otherwise have been.

A special “thank you” goes to Jean Twenge, San Diego State University, for her contribution to Chapter 2, “The Self in a Social World.” Drawing on her extensive knowledge of and research on the self and cultural changes, Professor Twenge updated and revised this chapter.

This new edition retains many of the improvements contributed by consul- tants and reviewers on the first nine editions. To these esteemed colleagues I therefore remain indebted. I have also benefited from the input of instructors who reviewed the ninth edition in preparation for this revision, rescuing me from occasional mistakes and offering constructive suggestions (and encour- agement). I am indebted to each of these many colleagues:

Hope College, Michigan, has been wonderfully supportive of these successive editions. Both the people and the environment have helped make the gestation of ten editions of Social Psychology a pleasure. At Hope College, poet Jack Ridl helped shape the voice you will hear in these pages. Kathy Adamski has again contributed her good cheer and secretarial support. And Kathryn Brownson did library research, edited and prepared the manuscript, managed the paper flow, proofed the pages and art, and prepared the bibliography. All in all, she midwifed this book.

Were it not for the inspiration of Nelson Black of McGraw-Hill, writing a textbook never would have occurred to me. Alison Meersschaert guided and encouraged the formative first edition. Publisher Mike Sugarman helped envision the execution of the ninth and tenth editions and their teaching supplements. Augustine Laferrera ably served as editorial coordinator. Sarah Colwell managed the supplements, and production editor Holly Paulsen patiently guided the process of converting the man- uscript into the finished book, assisted by copyeditor Janet Tilden’s fine-tuning.

After hearing countless dozens of people say that this book’s supplements have taken their teaching to a new level, I also pay tribute to Martin Bolt (Calvin College), both for his writing the study guide and for his pioneering the extensive instruc- tor’s resources, with their countless ready-to-use demonstration activities.

How fortunate we are to have as part of our team Jonathan Mueller (North Cen- tral College) as author of the instructor’s resources for the eighth, ninth, and tenth editions. Jon is able to draw on his acclaimed online resources for the teaching of social psychology and his monthly listserv offering resources to social psychology instructors (see jonathan.mueller.faculty.noctrl.edu/crow).

Kudos also go to Donna Walsh for her gift to the teaching of Social Psychology by authoring the testing resources.

To all in this supporting cast, I am indebted. Working with all these people has made the creation of this book a stimulating, gratifying experience.

Postscript: Why I wrote this book

T here once was a man whose second wife was a vain and selfish woman. This woman’s two daughters were similarly vain and selfish. The man’s own daughter, however, was meek and unselfish. This

sweet, kind daughter, whom we all know as Cinderella, learned early

on that she should do as she was told, accept ill treatment and insults,

and avoid doing anything to upstage her stepsisters and their mother.

But then, thanks to her fairy godmother, Cinderella was able to

escape her situation for an evening and attend a grand ball, where she

attracted the attention of a handsome prince. When the love-struck

prince later encountered Cinderella back in her degrading home, he

failed to recognize her.

Implausible? The folktale demands that we accept the power of the

situation. In the presence of her oppressive stepmother, Cinderella was

humble and unattractive. At the ball, Cinderella felt more beautiful—

and walked and talked and smiled as if she were. In one situation, she

cowered. In the other, she charmed.

The French philosopher-novelist Jean-Paul Sartre (1946) would

have had no problem accepting the Cinderella premise. We humans

are “first of all beings in a situation,” he wrote. “We cannot be distin-

guished from our situations, for they form us and decide our possibili-

ties” (pp. 59–60, paraphrased).

4 Chapter 1 Introducing Social Psychology

What Is Social Psychology? Social psychology is a science that studies the influences of our situations, with special attention to how we view and affect one another. More precisely, it is the sci- entific study of how people think about, influence, and relate to one another ( Figure 1.1 ).

Social psychology lies at psychology’s boundary with sociology. Compared with sociology (the study of people in groups and societies), social psychology focuses more on individuals and uses more experimentation. Compared with personality psychology, social psychology focuses less on individuals’ differences and more on how individuals, in general, view and affect one another.

Social psychology is still a young science. The first social psychology experi- ments were reported barely more than a century ago (1898), and the first social psychology texts did not appear until just before and after 1900 (Smith, 2005). Not until the 1930s did social psychology assume its current form. And not until World War II did it begin to emerge as the vibrant field it is today.

Social psychology studies our thinking, influence, and relationships by asking questions that have intrigued us all. Here are some examples:

How Much of Our Social World Is Just in Our Heads? As we will see in later chapters, our social behavior varies not just with the objective situation but also with how we construe it. Social beliefs can be self-fulfilling. For example, happily married people will attribute their spouse’s acid remark (“Can’t you ever put that where it belongs?”) to something external (“He must have had a frustrating day”). Unhappily married people will attribute the same remark to a mean disposition (“Is he ever hostile!”) and may respond with a coun- terattack. Moreover, expecting hostility from their spouse, they may behave resentfully, thereby eliciting the hostility they expect. Would People Be Cruel If Ordered? How did Nazi Germany conceive and implement the unconscionable slaughter of 6 million Jews? Those evil acts occurred partly because thousands of people followed orders. They put the prisoners on trains, herded them into crowded “showers,” and poisoned them with gas. How could people engage in such horrific actions? Were those individuals normal human beings? Stanley Milgram (1974) wondered. So he set up a situation where people were ordered to administer increasing

levels of electric shock to someone who was having difficulty learning a series of words. As we will see in Chapter 6, nearly two-thirds of the participants fully complied. To Help? Or to Help Oneself? As bags of cash tumbled from an armored truck one fall day, $2 million was scattered along a Columbus, Ohio, street. Some motorists stopped to help, returning $100,000. Judging from the $1,900,000 that disap- peared, many more stopped to help themselves. (What would you have done?) When similar incidents occurred several months later in San Francisco and Toronto, the results were the same: Passersby grabbed most of the money (Bowen, 1988). What situations trigger people to be helpful or greedy? Do some cultural contexts—perhaps villages and small towns— breed greater helpfulness? A common thread runs through these questions: They all deal

with how people view and affect one another. And that is what social psychology is all about. Social psychologists study attitudes and beliefs, conformity and independence, love and hate.

Social Psychology’s Big Ideas What are social psychology’s big lessons—its overarching themes? In many aca- demic fields, the results of tens of thousands of studies, the conclusions of thou- sands of investigators, and the insights of hundreds of theorists can be boiled down to a few central ideas. Biology offers us principles such as natural selection and adaptation. Sociology builds on concepts such as social structure and organization. Music harnesses our ideas of rhythm, melody, and harmony.

What concepts are on social psychology’s short list of big ideas? What themes, or fundamental principles, will be worth remembering long after you have forgotten most of the details? My short list of “great ideas we ought never to forget” includes these, each of which we will explore further in chapters to come ( Figure 1.2 ).

We Construct Our Social Reality We humans have an irresistible urge to explain behavior, to attribute it to some cause, and therefore to make it seem orderly, predictable, and controllable. You and I may react differently to similar situations because we think differently. How we react to a friend’s insult depends on whether we attribute it to hostility or to a bad day.

A 1951 Princeton-Dartmouth football game provided a classic demonstration of how we construct reality (Hastorf & Cantril, 1954; see also Loy & Andrews, 1981). The game lived up to its billing as a grudge match; it turned out to be one of the roughest and dirtiest games in the history of either school. A Princeton All- American was gang-tackled, piled on, and finally forced out of the game with a broken nose. Fistfights erupted, and there were further injuries on both sides. The whole performance hardly fit the Ivy League image of upper-class gentility.

Not long afterward, two psychologists, one from each school, showed films of the game to students on each campus. The students played the role of scientist- observer, noting each infraction as they watched and who was responsible for it. But they could not set aside their loyalties. The Princeton students, for example, saw twice as many Dartmouth violations as the Dartmouth students saw. The con- clusion: There is an objective reality out there, but we always view it through the lens of our beliefs and values.

6 Chapter 1 Introducing Social Psychology

We are all intuitive scientists. We explain people’s behavior, usually with enough speed and accuracy to suit our daily needs. When someone’s behavior is consistent and distinctive, we attribute that behavior to his or her personality. For example, if you observe someone who makes repeated snide comments, you may infer that this person has a nasty disposition, and then you might try to avoid the person.

Our beliefs about ourselves also matter. Do we have an optimistic outlook? Do we see ourselves as in control of things? Do we view ourselves as relatively supe- rior or inferior? Our answers influence our emotions and actions. How we construe the world, and ourselves, matters.

Our Social Intuitions Are Often Powerful but Sometimes Perilous Our instant intuitions shape our fears (is flying dangerous?), impressions (can I trust him?), and relationships (does she like me?). Intuitions influence presi- dents in times of crisis, gamblers at the table, jurors assessing guilt, and person- nel directors screening applicants. Such intuitions are commonplace.

Indeed, psychological science reveals a fascinating unconscious mind—an intuitive backstage mind—that Freud never told us about. More than psychologists realized until recently, thinking occurs offstage, out of sight. Our intuitive capaci- ties are revealed by studies of what later chapters will explain: “automatic pro- cessing,” “implicit memory,” “heuristics,” “spontaneous trait inference,” instant emotions, and nonverbal communication. Thinking, memory, and attitudes all operate on two levels—one conscious and deliberate, the other unconscious and automatic. “Dual processing,” today’s researchers call it. We know more than we know we know.

Introducing Social Psychology Chapter 1 7

Intuition is huge, but intuition is also perilous. An example: As we cruise through life, mostly on automatic pilot, we intuitively judge the likeli- hood of things by how easily various instances come to mind. Especially since September 11, 2001, we carry readily available mental images of plane crashes. Thus, most people fear flying more than driving, and many will drive great distances to avoid risking the skies. Actually, we’re many times safer (per mile traveled) in a commercial plane than in a motor vehicle (in the United States, air travel was 230 times safer between 2002 and 2005, reports the National Safety Council [2008]).

Even our intuitions about ourselves often err. We intuitively trust our memories more than we should. We misread our own minds; in ex – periments, we deny being affected by things that do influence us. We mispredict our own feelings—how bad we’ll feel a year from now if we lose our job or our romance breaks up, and how good we’ll feel a year from now, or even a week from now, if we win our state’s lottery. And we often mispredict our own future. For example, when selecting clothes, people approaching middle age will still buy snug (“I anticipate shedding a few pounds”); rarely does anyone say, more real- istically, “I’d better buy a relatively loose fit; people my age tend to put on pounds.”

Our social intuitions, then, are noteworthy for both their powers and their perils. By reminding us of intuition’s gifts and alerting us to its pitfalls, social psy- chologists aim to fortify our thinking. In most situations, “fast and frugal” snap judgments serve us well enough. But in others, where accuracy matters—as when needing to fear the right things and spend our resources accordingly—we had best restrain our impulsive intuitions with critical thinking. Our intuitions and uncon- scious information processing are routinely powerful and sometimes perilous.

Social Influences Shape Our Behavior We are, as Aristotle long ago observed, social animals. We speak and think in words we learned from others. We long to connect, to belong, and to be well thought of. Matthias Mehl and James Pennebaker (2003) quantified their University of Texas students’ social behavior by inviting them to wear microcassette recorders and microphones. Once every 12 minutes during their waking hours, the computer- operated recorder would imperceptibly record for 30 seconds. Although the obser- vation period covered only weekdays (including class time), almost 30 percent of the students’ time was spent in conversation. Relationships are a large part of being human.

As social creatures, we respond to our immediate contexts. Sometimes the power of a social situation leads us to act contrary to our expressed attitudes. Indeed, powerfully evil situations sometimes overwhelm good intentions, induc- ing people to agree with falsehoods or comply with cruelty. Under Nazi influence, many decent-seeming people became instruments of the Holocaust. Other situa- tions may elicit great generosity and compassion. After the 9/11 catastrophe, New York City was overwhelmed with donations of food, clothing, and help from eager volunteers.

Social cognition matters. Our behavior is influenced not just by the objective situation, but also by how we construe it. © The New Yorker Collection, 2005, Lee Lorenz, from cartoonbank.com. All Rights Reserved.

The power of the situation was also dramatically evident in varying attitudes toward the 2003 invasion of Iraq. Opinion polls revealed that Americans and Israelis overwhelmingly favored the war. Their distant cousins elsewhere in the world overwhelmingly opposed it. Tell me where you live and I’ll make a reason- able guess as to what your attitudes were as the war began. Tell me your edu- cational level and what media you watch and read, and I’ll make an even more confident guess. Our situations matter.

Our cultures help define our situations. For example, our standards regarding promptness, frankness, and clothing vary with our culture.

• Whether you prefer a slim or voluptuous body depends on when and where in the world you live.

• Whether you define social justice as equality (all receive the same) or as equity (those who earn more receive more) depends on whether your ideology has been shaped more by socialism or by capitalism.

• Whether you tend to be expressive or reserved, casual or formal, hinges partly on your culture and your ethnicity.

• Whether you focus primarily on yourself—your personal needs, desires, and morality—or on your family, clan, and communal groups depends on how much you are a product of modern Western individualism.

Social psychologist Hazel Markus (2005) sums it up: “People are, above all, mal- leable.” Said differently, we adapt to our social context. Our attitudes and behavior are shaped by external social forces.

Personal Attitudes and Dispositions Also Shape Behavior Internal forces also matter. We are not passive tumbleweeds, merely blown this way and that by the social winds. Our inner attitudes affect our behavior. Our polit- ical attitudes influence our voting behavior. Our smoking attitudes influence our susceptibility to peer pressures to smoke. Our attitudes toward the poor influence our willingness to help them. (As we will see, our attitudes also follow our behav- ior, which leads us to believe strongly in those things we have committed ourselves to or suffered for.)

Personality dispositions also affect behavior. Facing the same situation, differ- ent people may react differently. Emerging from years of political imprisonment, one person exudes bitterness and seeks revenge. Another, such as South Africa’s Nelson Mandela, seeks reconciliation and unity with his former enemies. Attitudes and personality influence behavior.

Social Behavior Is Biologically Rooted Twenty-first-century social psychology is providing us with ever-growing insights into our behavior’s biological foundations. Many of our social behaviors reflect a deep biological wisdom.

Everyone who has taken introductory psychology has learned that nature and nurture together form who we are. As the area of a rectangle is determined by both its length and its width, so do biology and experience together create us. As evolutionary psychologists remind us (see Chapter 5), our inherited human nature predisposes us to behave in ways that helped our ancestors survive and reproduce. We carry the genes of those whose traits enabled them and their children to survive and reproduce. Thus, evolutionary psychologists ask how natural selection might predispose our actions and reactions when dating and mating, hating and hurting, caring and sharing. Nature also endows us with an

enormous capacity to learn and to adapt to varied environments. We are sensi- tive and responsive to our social context.

If every psychological event (every thought, every emotion, every behavior) is simultaneously a biological event, then we can also examine the neurobiology that underlies social behavior. What brain areas enable our experiences of love and con- tempt, helping and aggression, perception and belief? How do brain, mind, and behavior function together as one coordinated system? What does the timing of brain events reveal about how we process information? Such questions are asked by those in social neuroscience (Cacioppo & others, 2007).

Social neuroscientists do not reduce complex social behaviors, such as helping and hurting, to simple neural or molecular mechanisms. Their point is this: To understand social behavior, we must consider both under-the-skin (biological) and between-skins (social) influences. Mind and body are one grand system. Stress hor- mones affect how we feel and act. Social ostracism elevates blood pressure. Social support strengthens the disease-fighting immune system. We are bio-psycho-social organisms. We reflect the interplay of our biological, psychological, and social influ- ences. And that is why today’s psychologists study behavior from these different levels of analysis.

Social Psychology’s Principles Are Applicable in Everyday Life Social psychology has the potential to illuminate your life, to make visible the sub- tle influences that guide your thinking and acting. And, as we will see, it offers many ideas about how to know ourselves better, how to win friends and influence people, how to transform closed fists into open arms.

Scholars are also applying social psychological insights. Principles of social thinking, social influence, and social relations have implications for human health and well-being, for judicial procedures and juror decisions in courtrooms, and for influencing behaviors that will enable an environmentally sustainable human future.

As but one perspective on human existence, psychological science does not seek to engage life’s ultimate questions: What is the meaning of human life? What should be our purpose? What is our ultimate destiny? But social psychology does give us a method for asking and answering some exceedingly interesting and important questions. Social psychology is all about life—your life: your beliefs, your attitudes, your relationships.

The rest of this chapter takes us inside social psychology. Let’s first consider how social psychologists’ own values influence their work in obvious and subtle ways. And then let’s focus on this chapter’s biggest task: glimpsing how we do social psy- chology. How do social psychologists search for explanations of social thinking, social influence, and social relations? And how might you and I use these analytical tools to think smarter?

Throughout this book, a brief summary will conclude each major section. I hope these summaries will help you assess how well you have learned the material in each section.

Social psychology is the scientific study of how peo- ple think about, influence, and relate to one another. Its central themes include the following:

• How we construe our social worlds • How our social intuitions guide and sometimes

deceive us

• How our social behavior is shaped by other peo- ple, by our attitudes and personalities, and by our biology

• How social psychology’s principles apply to our everyday lives and to various other fields of study

10 Chapter 1 Introducing Social Psychology

Social Psychology and Human Values Social psychologists’ values penetrate their work in ways both obvious and subtle. What are such ways?

Social psychology is less a collection of findings than a set of strategies for answering questions. In science, as in courts of law, personal opinions are inadmis- sible. When ideas are put on trial, evidence determines the verdict.

But are social psychologists really that objective? Because they are human beings, don’t their values —their personal convictions about what is desirable and how people ought to behave—seep into their work? If so, can social psychology really be scientific?

Obvious Ways Values Enter Psychology Values enter the picture when social psychologists choose research topics. It was no accident that the study of prejudice flourished during the 1940s as fascism raged in Europe; that the 1950s, a time of look-alike fashions and intolerance of differ- ing views, gave us studies of conformity; that the 1960s saw interest in aggression increase with riots and rising crime rates; that the feminist movement of the 1970s helped stimulate a wave of research on gender and sexism; that the 1980s offered a resurgence of attention to psychological aspects of the arms race; and that the 1990s and the early twenty-first century were marked by heightened interest in how peo- ple respond to diversity in culture, race, and sexual orientation. Social psychology reflects social history (Kagan, 2009).

Values differ not only across time but also across cultures. In Europe, people take pride in their nationalities. The Scots are more self-consciously distinct from

the English, and the Austrians from the Germans, than are similarly adjacent Michiganders from Ohioans. Conse- quently, Europe has given us a major theory of “social iden- tity,” whereas American social psychologists have focused more on individuals—how one person thinks about oth- ers, is influenced by them, and relates to them (Fiske, 2004; Tajfel, 1981; Turner, 1984). Australian social psychologists have drawn theories and methods from both Europe and North America (Feather, 2005).

Values also influence the types of people who are attracted to various disciplines (Campbell, 1975a; Moynihan, 1979). At your school, do the students majoring in the humanities, the arts, the natural sciences, and the social sciences differ noticeably from one another? Do social psychology and sociology attract people who are—for example—relatively eager to challenge tradition, people more inclined to shape the future than preserve the past?

Finally, values obviously enter the picture as the object of social-psychological analysis. Social psychologists inves- tigate how values form, why they change, and how they in – fluence attitudes and actions. None of that, however, tells us which values are “right.”

Not-So-Obvious Ways Values Enter Psychology We less often recognize the subtler ways in which value commitments masquerade as objective truth. Consider three not-so-obvious ways values enter psychology.

Introducing Social Psychology Chapter 1 11

THE SUBJECTIVE ASPECTS OF SCIENCE Scientists and philosophers now agree: Science is not purely objective. Scientists do not simply read the book of nature. Rather, they interpret nature, using their own mental categories. In our daily lives, too, we view the world through the lens of our preconceptions. Pause a moment: What do you see in Figure 1.3 ? Can you see a Dalmatian sniffing the ground at the picture’s center? Without that preconcep- tion, most people are blind to the Dalmatian. Once your mind grasps the concept, it informs your interpretation of the picture—so much so that it becomes difficult not to see the dog.

This is the way our minds work. While reading these words, you have been unaware that you are also looking at your nose. Your mind blocks from awareness something that is there, if only you were predisposed to perceive it. This tendency to prejudge reality based on our expectations is a basic fact about the human mind.

Because scholars at work in any given area often share a common viewpoint or come from the same culture, their assumptions may go unchallenged. What we take for granted—the shared beliefs that some European social psychologists call our social representations (Augoustinos & Innes, 1990; Moscovici, 1988, 2001)—are often our most important yet most unexamined convictions. Sometimes, however, someone from outside the camp will call attention to those assumptions. During the 1980s feminists and Marxists exposed some of social psychology’s unexam- ined assumptions. Feminist critics called attention to subtle biases—for example, the political conservatism of some scientists who favored a biological interpreta- tion of gender differences in social behavior (Unger, 1985). Marxist critics called attention to competitive, individualist biases—for example, the assumption that conformity is bad and that individual rewards are good. Marxists and feminists, of course, make their own assumptions, as critics of academic “political correctness” are fond of noting. Social psychologist Lee Jussim (2005), for example, argues that progressive social psychologists sometimes feel compelled to deny group differ- ences and to assume that stereotypes of group difference are never rooted in reality but always in racism.

“Science does not simply describe and explain nature; it is part of the interplay between nature and our- selves; it describes nature as exposed to our method of questioning.”

PHILOSOPHY, 1958

12 Chapter 1 Introducing Social Psychology

In Chapter 3 we will see more ways in which our preconceptions guide our interpretations. As those Princeton and Dartmouth football fans remind us, what guides our behavior is less the situation-as-it-is than the situation-as-we- construe-it.

PSYCHOLOGICAL CONCEPTS CONTAIN HIDDEN VALUES Implicit in our understanding that psychology is not objective is the realization that psychologists’ own values may play an important part in the theories and judgments they support. Psychologists may refer to people as mature or immature, as well adjusted or poorly adjusted, as mentally healthy or mentally ill. They may talk as if they were stating facts, when they are really making value judgments. Here are some examples:

Defining the Good Life. Values influence our idea of the best way to live our lives. The personality psychologist Abraham Maslow, for example, was known for his sensitive descriptions of “self-actualized” people—people who, with their needs for survival, safety, belonging, and self-esteem satis- fied, go on to fulfill their human potential. Few readers noticed that Maslow himself, guided by his own values, selected the sample of self-actualized people he described. The resulting description of self-actualized person- alities—as spontaneous, autonomous, mystical, and so forth—reflected Maslow’s personal values. Had he begun with someone else’s heroes—say, Napoleon, Alexander the Great, and John D. Rockefeller—his resulting description of self-actualization would have differed (Smith, 1978). Professional Advice. Psychological advice also reflects the advice giver’s personal values. When mental health professionals advise us how to get along

with our spouse or our co-workers, when child-rearing experts tell us how to handle our children, and when some psychologists advocate living free of concern for others’ expectations, they are expressing their personal values. (In Western cultures, those val- ues usually will be individualistic—encouraging what feels best for “me.” Non-Western cultures more often encourage what’s best for “we.”) Many people, unaware of those hidden values, defer to the “professional.” But professional psychologists cannot answer questions of ultimate moral obligation, of purpose and direction, and of life’s meaning. Forming Concepts. Hidden values even seep into psychology’s research-based concepts. Pretend you have taken a personality test and the psychologist, after scoring your answers, announces: “You scored high in self-esteem. You are low in anxiety. And you have exceptional ego-strength.” “Ah,” you think, “I sus- pected as much, but it feels good to know that.” Now another psychologist gives you a similar test. For some peculiar reason, this test asks some of the same questions. Afterward, the psy- chologist informs you that you seem defensive, for you scored high in “repressiveness.” “How could this be?” you wonder. “The other psychologist said such nice things about me.” It could be because all these labels describe the same set of responses (a tendency to say nice things about oneself and not to acknowl- edge problems). Shall we call it high self-esteem or defensive- ness? The label reflects the judgment.

Labeling. Value judgments, then, are often hidden within our social- psychological language—but that is also true of everyday language:

• Whether we label a quiet child as “bashful” on “cautious,” as “holding back” or as “an observer,” conveys a judgment.

Hidden (and not-so-hidden) values seep into psycho- logical advice. They permeate popular psychology books that offer guidance on living and loving.

• Whether we label someone engaged in guerrilla warfare a “terrorist” or a “freedom fi ghter” depends on our view of the cause.

• Whether we view wartime civilian deaths as “the loss of innocent lives” or as “collateral damage” affects our acceptance of such.

• Whether we call public assistance “welfare” or “aid to the needy” refl ects our political views.

• When “they” exalt their country and people, it’s nationalism; when “we” do it, it’s patriotism.

• Whether someone involved in an extramarital affair is practicing “open marriage” or “adultery” depends on one’s personal values.

• “Brainwashing” is social infl uence we do not approve of. • “Perversions” are sex acts we do not practice. • Remarks about “ambitious” men and “aggressive” women convey a

hidden message.

As these examples indicate, values lie hidden within our cultural definitions of mental health, our psychological advice for living, our concepts, and our psycho- logical labels. Throughout this book I will call your attention to additional examples of hidden values. The point is never that the implicit values are necessarily bad. The point is that scientific interpretation, even at the level of labeling phenomena, is a human activity. It is therefore natural and inevitable that prior beliefs and values will influence what social psychologists think and write.

Should we dismiss science because it has its subjective side? Quite the contrary: The realization that human thinking always involves interpretation is precisely why we need researchers with varying biases to undertake scientific analysis. By constantly checking our beliefs against the facts, as best we know them, we check and restrain our biases. Systematic observation and experimentation help us clean the lens through which we see reality.

• Social psychologists’ values penetrate their work in obvious ways, such as their choice of research topics and the types of people who are attracted to various fields of study.

• They also do this in subtler ways, such as their hid- den assumptions when forming concepts, choosing labels, and giving advice.

• This penetration of values into science is not a rea- son to fault social psychology or any other science. That human thinking is seldom dispassionate is precisely why we need systematic observation and experimentation if we are to check our cherished ideas against reality.

I Knew It All Along: Is Social Psychology Simply Common Sense? Do social psychology’s theories provide new insight into the human condition? Or do they only describe the obvious?

Many of the conclusions presented in this book may have already occurred to you, for social psychological phenomena are all around you. We constantly observe people thinking about, influencing, and relating to one another. It pays to discern what a facial expression predicts, how to get someone to do something, or whether to regard another as friend or foe. For centuries, philosophers, novelists, and poets have observed and commented on social behavior.

14 Chapter 1 Introducing Social Psychology

Does this mean that social psychology is just common sense in fancy words? Social psychology faces two contradictory criticisms: first, that it is trivial because it documents the obvious; second, that it is dangerous because its findings could be used to manipulate people.

We will explore the second criticism in Chapter 7. For the moment, let’s examine the first objection.

Do social psychology and the other social sciences simply formalize what any amateur already knows intuitively? Writer Cullen Murphy (1990) took that view: “Day after day social scientists go out into the world. Day after day they discover that people’s behavior is pretty much what you’d expect.” Nearly a half-century earlier, historian Arthur Schlesinger, Jr. (1949), reacted with similar scorn to social scientists’ studies of American World War II soldiers. Sociologist Paul Lazarsfeld (1949) reviewed those studies and offered a sample with interpretive comments, a few of which I paraphrase:

1. Better-educated soldiers suffered more adjustment problems than did less- educated soldiers. (Intellectuals were less prepared for battle stresses than street-smart people.)

2. Southern soldiers coped better with the hot South Sea Island climate than did Northern soldiers. (Southerners are more accustomed to hot weather.)

3. White privates were more eager for promotion than were Black privates. (Years of oppression take a toll on achievement motivation.)

4. Southern Blacks preferred Southern to Northern White officers. (Southern officers were more experienced and skilled in interacting with Blacks.)

As you read those findings, did you agree that they were basically common sense? If so, you may be surprised to learn that Lazarsfeld went on to say, “Every one of these statements is the direct opposite of what was actually found.” In reality, the studies found that less-educated soldiers adapted more poorly. Southerners were not more likely than northerners to adjust to a tropical climate. Blacks were more eager than Whites for promotion, and so forth. “If we had mentioned the actual results of the investigation first [as Schlesinger experienced], the reader would have labeled these ‘obvious’ also.”

One problem with common sense is that we invoke it after we know the facts. Events are far more “obvious” and predictable in hindsight than beforehand. Exper- iments reveal that when people learn the outcome of an experiment, that outcome suddenly seems unsurprising—certainly less surprising than it is to people who are simply told about the experimental procedure and the possible outcomes (Slovic & Fischhoff, 1977).

Likewise, in everyday life we often do not expect something to happen until it does. Then we suddenly see clearly the forces that brought the event about and feel unsurprised. Moreover, we may also misremember our earlier view (Blank & others, 2008). Errors in judging the future’s foreseeability and in remember- ing our past combine to create hindsight bias (also called the I-knew-it-all-along phenomenon ).

Thus, after elections or stock market shifts, most commentators find the turn of events unsurprising: “The market was due for a correction.” After the widespread flooding in New Orleans as a result of Hurricane Katrina in 2005, it seemed obvi- ous that public officials should have anticipated the situation: Studies of the levees’ vulnerability had been done. Many residents did not own cars and were too poor to afford transportation and lodging out of town. Meteorologic assessment of the storm’s severity clearly predicted an urgent need to put security and relief supplies in place. As the Danish philosopher-theologian Søren Kierkegaard put it, “Life is lived forwards, but understood backwards.”

If hindsight bias is pervasive, you may now be feeling that you already knew about this phenomenon. Indeed, almost any conceivable result of a psychological experiment can seem like common sense— after you know the result.

hindsight bias The tendency to exaggerate, after learning an outcome, one’s ability to have foreseen how something turned out. Also known as the I-knew-it- all-along phenomenon.

Introducing Social Psychology Chapter 1 15

You can demonstrate the phenomenon yourself. Take a group of people and tell half of them one psychological finding and the other half the opposite result. For example, tell half as follows:

Social psychologists have found that, whether choosing friends or falling in love, we are most attracted to people whose traits are different from our own. There seems to be wisdom in the old saying “Opposites attract.”

Tell the other half:

Social psychologists have found that, whether choosing friends or falling in love, we are most attracted to people whose traits are similar to our own. There seems to be wisdom in the old saying “Birds of a feather flock together.”

Ask the people first to explain the result. Then ask them to say whether it is “sur- prising” or “not surprising.” Virtually all will find a good explanation for which- ever result they were given and will say it is “not surprising.”

Indeed, we can draw on our stockpile of proverbs to make almost any result seem to make sense. If a social psychologist reports that separation intensifies romantic attraction, John Q. Public responds, “You get paid for this? Everybody knows that ‘absence makes the heart grow fonder.’” Should it turn out that separation weakens attraction, John will say, “My grandmother could have told you, ‘Out of sight, out of mind.’”

Karl Teigen (1986) must have had a few chuckles when he asked University of Leicester (England) students to evaluate actual proverbs and their opposites. When given the proverb “Fear is stronger than love,” most rated it as true. But so did stu- dents who were given its reversed form, “Love is stronger than fear.” Likewise, the genuine proverb “He that is fallen cannot help him who is down” was rated highly; but so too was “He that is fallen can help him who is down.” My favorites, however, were two highly rated proverbs: “Wise men make proverbs and fools repeat them” (authentic) and its made-up counterpart, “Fools make proverbs and wise men repeat them.” For more dueling proverbs, see “Focus On: I Knew It All Along.”

The hindsight bias cre- ates a problem for many psychology students. Some- times results are genuinely surprising (for example, that Olympic bronze medal- ists take more joy in their achievement than do sil- ver medalists). More often, when you read the results of experiments in your text- books, the material seems easy, even obvious. When you later take a multiple- choice test on which you must choose among sev- eral plausible conclusions, the task may become sur- prisingly difficult. “I don’t know what happened,” the befuddled student later moans. “I thought I knew the material.”

In hindsight, events seem obvious and predictable. ScienceCartoonsPlus.com

Is it more true that . . . Too many cooks spoil the broth. The pen is mightier than the sword. You can’t teach an old dog new tricks. Blood is thicker than water. He who hesitates is lost. Forewarned is forearmed.

Or that . . . Two heads are better than one. Actions speak louder than words. You’re never too old to learn.

Many kinfolk, few friends. Look before you leap. Don’t cross the bridge until you come to it.

Cullen Murphy (1990), managing editor of the Atlantic, faulted “sociology, psychol- ogy, and other social sciences for too often merely discerning the obvious or confirm- ing the commonplace.” His own casual survey of social science findings “turned up no ideas or conclusions that can’t be found in Bartlett’s or any other encyclopedia of quotations.” Nevertheless, to sift through competing sayings, we need research. Consider some dueling proverbs:

16 Chapter 1 Introducing Social Psychology

The I-knew-it-all-along phenomenon can have unfortunate consequences. It is conducive to arrogance—an overestimation of our own intellectual powers. More- over, because outcomes seem as if they should have been foreseeable, we are more likely to blame decision makers for what are in retrospect “obvious” bad choices than to praise them for good choices, which also seem “obvious.”

Starting after the morning of 9/11 and working backward, signals pointing to the impending disaster seemed obvious. A U.S. Senate investigative report listed the missed or misinterpreted clues (Gladwell, 2003), which included the follow- ing. The CIA knew that al Qaeda operatives had entered the country. An FBI agent sent a memo to headquarters that began by warning “the Bureau and New York of the possibility of a coordinated effort by Osama bin Laden to send students to the United States to attend civilian aviation universities and colleges.” The FBI ignored that accurate warning and failed to relate it to other reports that terrorists were planning to use planes as weapons. The president received a daily briefing titled “Bin Laden Determined to Strike Inside the United States” and stayed on holiday. “The dumb fools!” it seemed to hindsight critics. “Why couldn’t they con- nect the dots?”

But what seems clear in hindsight is seldom clear on the front side of history. The intelligence community is overwhelmed with “noise”—piles of useless infor- mation surrounding the rare shreds of useful information. Analysts must therefore be selective in deciding which to pursue, and only when a lead is pursued does it stand a chance of being connected to another lead. In the six years before 9/11, the FBI’s counterterrorism unit could never have pursued all 68,000 uninvestigated leads. In hindsight, the few useful ones are now obvious.

In the aftermath of the 2008 world financial crisis, it seemed obvious that govern- ment regulators should have placed safeguards against the ill-fated bank lending practices. But what was obvious in hindsight was unforeseen by the chief American regulator, Alan Greenspan, who found himself “in a state of shocked disbelief” at the economic collapse.

We sometimes blame ourselves for “stupid mistakes”—perhaps for not having handled a person or a situation better. Looking back, we see how we should have handled it. “I should have known how busy I would be at the semester’s end and started that paper earlier.” But sometimes we are too hard on ourselves. We forget that what is obvious to us now was not nearly so obvious at the time.

Physicians who are told both a patient’s symptoms and the cause of death (as determined by autopsy) sometimes wonder how an incorrect diagnosis could have been made. Other physicians, given only the symptoms, don’t find the di – agnosis nearly so obvious (Dawson & others, 1988). Would juries be slower to as – sume malpractice if they were forced to take a foresight rather than a hindsight perspective?

What do we conclude—that common sense is usually wrong? Sometimes it is. At other times, conventional wisdom is right—or it falls on both sides of an issue: Does happiness come from knowing the truth, or from preserving illusions? From being with others, or from living in peaceful solitude? Opinions are a dime a dozen. No matter what we find, there will be someone who foresaw it. (Mark Twain jested that Adam was the only person who, when saying a good thing, knew that nobody had said it before.) But which of the many competing ideas best fit reality? Research can specify the circumstances under which a common-sense truism is valid.

The point is not that common sense is predictably wrong. Rather, common sense usually is right— after the fact. We therefore easily deceive ourselves into thinking that we know and knew more than we do and did. And that is precisely why we need science to help us sift reality from illusion and genuine predictions from easy hindsight.

“It is easy to be wise after the event.”
