STEREOTYPE
In social psychology, a stereotype is a generalized belief about a particular category of people.[2]
It is an expectation that people might have about every person of a particular group.
The type of expectation can vary; it can be, for example, an expectation about the group's personality, preferences, appearance or ability.
Stereotypes are sometimes overgeneralized, overanalyzed, and inaccurate, and resistant to new information, but can sometimes be accurate.[3]
A stereotype does not necessarily need to be a negative assumption.
They may be positive, neutral, or negative.
A stereotypical caricature of a villain (i.e. generic melodramatic villain stock character, with handlebar moustache and black top-hat), particularly popular in early 20th century silent films and melodramas and popularized by Snidely Whiplash.
