Lecture 16: A Person in the World of People - Self and Other, Part I

What this lecture covers

This lecture opens a two-part unit on social psychology, the study of how people think about themselves, other people, and social groups. Paul Bloom begins with individual differences in social connectedness before turning to a set of well-documented biases in how people see themselves, and closes by introducing the fundamental attribution error, the tendency to over-explain other people's behavior by their personality rather than their situation.

After watching, you can describe the "six degrees of separation" idea and why some people function as social hubs, explain three robust self-enhancement biases (the spotlight effect, the transparency effect, and the "better than average" effect), describe how cognitive dissonance shapes behavior in situations like hazing and reward, and explain the fundamental attribution error and evidence that it varies across cultures.

Key ideas

• Social connectedness varies by person: Stanley Milgram's package-forwarding study is the basis for "six degrees of separation," and much of that connectivity runs through a small number of highly connected people, sometimes called "connectors."
• The spotlight effect: people consistently overestimate how much others notice them, such as an embarrassing T-shirt, because everyone is more focused on themselves than on observing others.
• The transparency effect: people overestimate how visible their internal states (like lying or hidden feelings) are to others, even though most people are reasonably good at concealing them.
• The "better than average" (Lake Wobegon) effect: most people rate themselves above average on desirable traits like driving ability, teaching, or being a good student, which is statistically impossible if accurate.
• The self-serving attribution bias: people credit their own successes to ability and blame their failures on circumstances, while being far less generous when judging others' successes and failures.
• Cognitive dissonance: an uncomfortable mental state caused by holding inconsistent beliefs or ideas, which people resolve by changing their beliefs or feelings rather than their behavior, as in the insufficient-justification effect (valuing a task more when paid less to do it) and hazing (valuing group membership more after enduring humiliation to join).
• The fundamental attribution error: people tend to explain others' behavior by stable personality traits rather than situational factors, as illustrated by mistaking a quiz-show host for someone genuinely more intelligent, or confusing actors with the roles they play.
• Cross-cultural variation in attribution: comparisons between the United States and India suggest the fundamental attribution error is not a human universal but is stronger in cultures with an ideology of individual control over one's destiny.

Walkthrough

Social psychology and connections between people (0:00)

Bloom introduces social psychology as the study of how people understand themselves, other people, and groups, motivating it with the public fascination with celebrity relationships. He describes Stanley Milgram's small-world experiment, in which randomly chosen people in Omaha successfully routed a package to a stranger in Massachusetts through an average of about six intermediaries, and explains how connections tend to flow disproportionately through a small number of well-connected "hub" people, illustrated with the "Six Degrees of Kevin Bacon" game and a Malcolm Gladwell-designed in-class exercise where students count how many names they recognize from a phone-book sample.

Aspects of the self: the spotlight and transparency effects (15:56)

The lecture turns to the psychology of the self, starting with Tom Gilovich's research on the spotlight effect, demonstrated by an experiment where students wore embarrassing T-shirts and dramatically overestimated how many people noticed. Bloom connects this to research on regret, where people more often regret things they didn't try out of fear of embarrassment than things they did try. He then describes the transparency effect, illustrated with an in-class lie-detection demonstration, where people overestimate how obvious their lies or hidden feelings are to others, even though observers are often no better than chance at spotting them.

Aspects of the self: you're terrific! (22:39)

Bloom presents the "better than average" or Lake Wobegon effect, where most people rate themselves above average on desirable traits such as driving, teaching, or being a good partner, something that cannot be true of a majority by definition. He offers two possible explanations, a feedback pattern that emphasizes praise over criticism, and people applying self-serving criteria for what "good" means, and connects this to the self-serving attribution bias, where people attribute their own successes to ability and their failures to circumstance.

Aspects of the self: cognitive dissonance (27:00)

The lecture covers Leon Festinger's cognitive dissonance theory, the idea that people are motivated to reduce the discomfort of holding inconsistent beliefs, often by changing their beliefs rather than their actions. Bloom illustrates this with the confirmation bias in media consumption, an M&M-choice experiment where people denigrate options they rejected, and Festinger's classic finding that people paid one dollar for a boring task rated it as more enjoyable than people paid twenty dollars, because they needed a way to justify doing it for so little. He extends this to real-world cases: doomsday believers who became more convinced after their prophecy failed, fraternity hazing that increases commitment to a group, unpaid political volunteers, and studies showing that rewarding children for an activity can reduce their later interest in doing it unprompted.

Self and the other (40:00)

Bloom introduces attribution theory, building on Fritz Heider's insight that people tend to explain others' behavior by appeal to personality traits rather than situational context, a pattern known as the fundamental attribution error. He illustrates this with a quiz-show study, where observers rated a randomly assigned question-asker as more intelligent than the question-answerer despite the roles being determined by a coin flip, and with the persistent public confusion of actors (such as Leonard Nimoy as Spock) with the characters they play. He notes cross-cultural research suggesting the error is stronger in Western cultures, which emphasize individual control over outcomes, than in cultures that place more emphasis on situational or fate-based explanations, as seen in differing news coverage of crime in the United States versus India.

How we think about other people (50:03)

The lecture closes by summarizing the asymmetry between generous self-perception and less forgiving judgments of others, then surveys factors that predict liking beyond kindness or intelligence: physical proximity (most people's closest friends live or work near them), the mere exposure effect (repeated exposure to something increases liking, even without conscious memory of having seen it before), similarity between friends and partners, and physical attractiveness, which Bloom connects to the "Matthew effect," where attractive people are perceived and treated more favorably across many domains, potentially reinforcing real advantages over time.

Before you watch

• This lecture references sexual attractiveness research covered earlier in the course, so some familiarity with that discussion of mate preference is useful but not required.
• No specific prior knowledge is assumed beyond general familiarity with basic psychological terms used earlier in the course, such as operant conditioning, which is referenced briefly when discussing reward and children's motivation.
• This is the first of a two-lecture sequence on social psychology; the second lecture continues with how people think about other people and social groups.

Check your understanding

1. What did Milgram's small-world experiment find about the number of steps needed to connect strangers, and what role do highly connected "hub" people play in that finding?
2. How does the spotlight effect differ from the transparency effect?
3. Why did participants paid one dollar for a boring task rate it as more enjoyable than participants paid twenty dollars, according to cognitive dissonance theory?
4. What does the quiz-show study reveal about the fundamental attribution error, and how does cross-cultural research complicate the claim that this error is universal?
5. Name two factors, besides kindness or intelligence, that the lecture identifies as predicting whether we like another person.
