Social perception comes from deep seated beliefs about some categorizations.
Explanation:
Categorizations of how people who speak, look or dress a certain way exist due to a wide variety of factors that social and political and also economic. The belief that is formed about a person at first sight often stems from this same instinct.
This instinct cannot really be done away with so these snap judgement can be worked around by the way people present themselves. An exotic name brings about the stereotypes of a place while clothes usually show the class the person belongs to.
