Main Difference
The main difference between Prejudice and Bias is that the Prejudice is a prejudgment, or forming an opinion before becoming aware of the relevant facts of a case and Bias is a inclination or outlook to present or hold a partial perspective.
Prejudice
Prejudice is an affective feeling towards a person or group member based solely on their group membership. The word is often used to refer to preconceived, usually unfavorable, feelings towards people or a person because of their sex, gender, beliefs, values, social class, age, disability, religion, sexuality, race/ethnicity, language, nationality, beauty, occupation, education, criminality, sport team affiliation or other personal characteristics. In this case, it refers to a positive or negative evaluation of another person based on their perceived group membership.
Prejudice can also refer to unfounded beliefs and it may include “any unreasonable attitude that is unusually resistant to rational influence”. Gordon Allport defined prejudice as a “feeling, favorable or unfavorable, toward a person or thing, prior to, or not based on, actual experience”. For the evolutionary psychology perspective, see Prejudice from an evolutionary perspective. Auestad (2015) defines prejudice as characterized by ‘symbolic transfer’, transfer of a value-laden meaning content onto a socially formed category and then on to individuals who are taken to belong to that category, resistance to change, and overgeneralization.
Bias
Bias is prejudice in favour of or against one thing, person, or group compared with another, usually in a way considered to be unfair.
Biases can be learned implicitly within cultural contexts. People may develop biases toward or against an individual, an ethnic group, a sexual or gender identity, a nation, a religion, a social class, a political party, theoretical paradigms and ideologies within academic domains, or a species. Biased means one-sided, lacking a neutral viewpoint, or not having an open mind. Bias can come in many forms and is related to prejudice and intuition.
In science and engineering, a bias is a systematic error. Statistical bias results from an unfair sampling of a population, or from an estimation process that does not give accurate results on average.
