Editing Prejudice (section)

===Contact hypothesis===
The [[contact hypothesis]] predicts that prejudice can only be reduced when in-group and out-group members are brought together.<ref name="Aronson, E. 2010">Aronson, E., Wilson, T. D., & Akert, R. M.

Academics Thomas Pettigrew and Linda Tropp conducted a [[meta-analysis]] of 515 studies involving a quarter of a million participants in 38 nations to examine how intergroup contact reduces prejudice. They found that three [[Mediation (statistics)|mediators]] are of particular importance: Intergroup contact reduces prejudice by (1) enhancing knowledge about the outgroup, (2) reducing anxiety about intergroup contact, and (3) increasing [[empathy]] and perspective-taking. While all three of these mediators had mediational effects, the mediational value of increased knowledge was less strong than anxiety reduction and empathy.<ref>{{cite journal |last1= Pettigrew |first1= Thomas F. |last2= Tropp |first2= Linda R. |year= 2008 |title= How does intergroup contact reduce prejudice?
