Stereotyping, Prejudice, and Social Perception
Eyewitness Testimony • Mistaken identification • Largest single cause of false conviction • Accounts for more criminal convictions of innocent people than all other causes combined • In lineups, witnesses pick “filler” suspects approximately 33% of the time • Of 235 cases exonerated by DNA, 77% were convicted, in part, on the basis of faulty eyewitness testimony • Average time between arrest and exoneration = 12 years
Race Affects Recognition Accuracy • Cross Race Recognition Deficit or Own-Race Effect • 1.56 times more likely mistaken ID • 1.4 times more likely correct ID for same race • Kindergarteners • 3rd graders • Adults • Cross-culturally • Of the cases of the exonerated involving eyewitness testimony, 40% involved cross-race recognition
Cross-Race Recognition Deficit • Contact/Familiarity • Lack of expertise as to the features that actually distinguish outgroup members from one another • But, contact accounts for only about 2% of the variance in the CRRD • Feature coding asymmetry for outgroups • Based on motivation to individuate ingroup but not outgroup members • Code race-specifying features at expense of individuating features
Motivation and Cross-Race Recognition Pauker et al., 2009
Racial Stereotypes and Social Cognition • Stereotype: A cognitive schema that contains a person’s knowledge, beliefs, and expectancies about a human group • Allow you to anticipate the behavior of others • Allow you to understand and interpret behavior • Especially if it is ambiguous • Fill in the blanks • Allow you to organize and structure your social experiences • They serve these functions even if they are objectively inaccurate
Stereotypes and Memory • Outgroup recognition is particularly poor when targets are paired with stereotypic behaviors • For example, Black targets are particularly likely to be misidentified as the authors of hostile or criminal behavior versus kind or pro-social behavior • People use the stereotype to reconstruct who must have engaged in the behavior Sherman et al., 1998, 2000
Stereotyping and Attention • Black faces draw and hold attention of White observers • Particularly to the extent that perceivers associate Blacks with danger • Just like spiders, snakes, angry faces • Even when faces are presented too quickly to be noticed Donders et al., 2008
Stereotyping and Attention • Surreptitiously activating thoughts of crime enhances this effect • Study conducted with police officers • However, greater attention was associated with false recognition of faces that were more stereotypically “Black” than the ones that actually appeared • Thoughts of crime drew attention to Black faces, but distorted the memories of those faces to be stereotypical • More attention does not necessarily mean better memory if the attention is biased by stereotypic expectancies • May contribute to cross-race errors in eyewitness identification Eberhardt et al., 2005
Stereotypes and Construal • Stereotypes affect basic aspects of face perception • Black men seem to anger more quickly and smile more slowly than white men • May influence encoding and subsequent memory of potential defendants Hugenberg & Bodenhausen, 2003
Stereotypes and Construal “Two residents wade through chest-deep water after finding bread and soda from a local grocery store after Hurricane Katrina”
Stereotypes and Construal “Looters hit a drug store in the French Quarter district of New Orleans”
FASTER, MORE ACCURATE SLOWER, LESS ACCURATE Payne, 2001

Potential influence on misidentification and worse Amadou Diallo
Correll et al., 2002 • Subjects paid for accurate performance False Kills per 20 Targets
Stereotypes and Sentencing • Longer sentences given for stereotypic crimes • Assault: Latino > Caucasian • Embezzlement: Caucasian > Latino • Attributions • Stereotypical = intentional, likely to be repeated • Counter-stereotypical = special situation, not likely to be repeated Bodenhausen & Wyer, 1985
Stereotypes and the Death Penalty • More stereotypically “Black” convicts are more likely to receive the death penalty • But only for killing White people, not Black people Eberhardt et al., 2006
Prejudice Enhances all of these Effects • Prejudice = negative evaluations of social groups • Not necessarily endorsed prejudice • Most people won’t openly admit to prejudice • Sometimes we are unaware of our own subtle biases • Implicit measures of prejudice prevent intentional misrepresentation and reveal biases of which we may be unaware

Implicit Prejudice • Some facts: • A large majority (85%) of non-Black Americans show a pro-White bias • About 1/3 Black Americans show pro-White, 1/3 show no bias, and 1/3 show pro-Black bias • Scores on the IAT and other implicit measures do not correlate with scores on explicit measures (e.g., rating scale, questionnaires) • Solution to “unwilling & unable” problems • Predict perceptual and behavioral biases better than prejudice measured with scales/questionnaires
