The psychological process that leads to people making generalizations about groups of people is called

attribution
stereotyping
implicit personality theory
primary-recency
self-fulfilling prophecy

The answer is stereotyping.

Explanation:

Stereotyping is when someone makes generalization on groups of people. Like example, saying all girls love dolls and dresses, this is stereotyping since we associate girls with dolls and dresses without taking into consideration the uniqueness of each individual.

While self-fulfilling prophecy is being the person others expect you to be. Example: A child who is told by everyone that he or she is smart will eventually become smart or smarter.

Attribution, on the other hand, is an action caused by what is observed.

Implicit personality theory are biases that one person makes in forming impressions of other person.

Primary-recency is when knowledge from events is more learned if it recently occured than those not recent.
