Tessa Perkins's five assumptions:
1. Stereotypes are not always negative. (Women have natural mothering instinct) Stereotypes aren't always negative. When stereotypes are made although they may have multiple stereotypes, negative stereotypes are often dominant.2. They are not always about minority groups or the less powerful, People make the assumption that stereotypes are aimed at the lower class however this isn't always the case as the upper class can have stereotypes placed upon them.
3. They can be held about one's own group, People can be part of a group which is collectively stereotyped. Within that group, although they share the same ideologies and values, individuals are then stereotyped based on our assumptions.
4. They are not rigid or unchanging, It is tough to change a stereotype once it has been assigned to a person as it is not always based on a singular factor but many which as a collective create a stereotype.
5. They are not always false, A stereotype must have some truth to them as the ideology would not have existed in the first place if there were no recognisable truths for people to stereotype.
