Close, friendly groups usually work well together, but they may face a problem involving an extreme form of conformity called __________

A) fundamental attribution error.
B) groupthink.
C) generational identity.
D) self-serving bias.

Groupthink refers to a situation within a group where there is such a strong desire for harmony and conformity that it overrides critical thinking and rational decision making. This can lead to poor decisions being made, as group members may not feel comfortable expressing dissenting opinions or ideas. This phenomenon is more likely to occur in close, friendly groups where there is a strong sense of group identity and cohesiveness.
