Today is a day of hate
When people have positive experiences with members of another group, they tend to generalize these experiences from the group member to the group as a whole. This process of member-to-group generalization results in less prejudice against the group. Notably, however, researchers have tended to ignore what happens when people have negative experiences with group members.
In a recent article, my colleagues and I proposed that negative experiences have an opposite but stronger effect on people’s attitudes towards groups.
