Need for social belonging

Essentialism bias

"I believe that social groups have a distinct and unchanging essence."

In-group bias

"My group is better than yours."

Outgroup homogeneity bias

“I tend to underestimate the differences among members of a group when I am not part of it.”

Social desirability bias

"To look good to these people, I'm going to say what they want to hear instead of what I really think."

Stereotypes and prejudices

“Women are gentle and motherly, so it's normal for them to stay home to take care of the children.”

Zero-sum bias

“I feel in competition with certain people and I think that any gain for them inevitably entails a loss for me.”
