What is a widely held but fixed and oversimplified idea of a particular type of person or thing called?

Richie, I think you’re confusing stereotype with typecast.

Queen Esther, It makes for simplified and simplistic storytelling. The good guys wear white hats, the bad ones, black. The best stories challenge those stereotypes.

People sometimes have a negative stereotype of a group, but say that someone they like is "one of the good ones." Experiencing a diverse range of people may help combat stereotypes. Today though it's easier than ever to avoid that with physical proximity replaced by make your own online environment. Ironically, the internet also makes it possible to interact with a much larger variety of people, as in this game. Ultimately free of manipulation, we're more alike than different, but manipulation yields big returns in money and power.

They usually always have stereotypes in movies!!

I’m a stef person

Tremain White, Sometimes knewledge becomes a burden and to offset the weight one quickly experiences ignorance, stereotypes. careful. ! ! !

Going to listen to the Specials now brilliant track.

In personal terms, the mistaken oversimplification of the particular - by recourse - only to the general = stereotype.
