Stereotype
stereotype as that consensus of opinion regarding the characteristics (traits, behaviors, etc.) attributed to a group. That is, stereotypes are organized beliefs or ideas about the characteristics associated with different social groups, such as the physical aspect, interests, occupations, ethnicities, etc. They are images, ideas, opinions or interpretations about the elements of a group in a simplified way.
Prejudice
Well, a prejudice is an attitude, usually of rejection, towards the members of a group. It is an unjustified reaction to a person originated by the person’s belonging to a particular social group. Prejudices are the positive and negative feelings and emotions you have about a social group and its members.
Difference between stereotype and prejudice
Therefore, what sets the stereotype apart from prejudice is the attitude shown, the reaction. A stereotype (positive or negative) is a justified opinion of cognitive component and the component of prejudice would be affective and irrational and unfair, is a negative attitude (or positive if it is the case). So, we could say that a stereotype could trigger a prejudiced attitude (negative or positive).
To summarize, an example, the stereotype that women are the best candidates to perform secretarial duties could trigger a negative prejudice towards a good male candidate, discarding the selection process for the simple fact of being male, or Either the coworkers themselves might have negative prejudicial attitudes toward a man for performing “women’s” work.
Another example of a stereotype is the idea that all politicians are corrupt, negative prejudice would occur when despite not knowing whether those in your city are or not, not to vote as a negative attitude before the group of politicians.
