Are these people racist?
1999 4 police officer shot him down social psychologists wanted to research it
in the words of the police officers (the book) clear description man fit the
description of a serial rapist just standing there

Shooter task implicit measure of prejudice: participants have the choice to shoot or
not to shoot when they see a person (holding guns or wallets)
The amount of bias you show vs. armed black targets is not predicted by how
prejudice you are predicted by knowledge/awareness of those stereotypes
Ingroups vs. outgroups
Ingroups any social group you’re a member of
Outgroup everybody else (us vs. them)
Ingroup favouritism: prefer members of ingroup, if divided into 2 groups randomly you
still favourite your group vs. other group
Doesn’t mean your hostile to members of an outgroup
Ingroup fav. happens automatically without reason
Outgroup hostility competing with other members
members of outgroup all the same; ingroups see variation and individuals
Different reasons: more familiar with ingroup, know everyone’s indiv. traits and
characteristics, focus on differences between indiv.
Outgroup their just different
Ways to reduce prejudice? increasing contact between members of diff. racial groups
Study: went to summer camp 2 diff. groups on opposite sides of the lake no existing
Phase 1: formed friends, learned other groups existence did many competitions
got really nasty and insulting towards other groups
Created prejudice and hostility see if they could get this to go away through phase 2
Phase 2: still fighting, contact not enough give them shared superordinate goals
had to work together to get some type of award required 2 groups to come and work
