Bias is a cognitive process in which people have some tendency to favor one idea or object over another, even though the two are not directly related. Unconscious bias is the unconscious tendency of people to favor one group of individuals over another. This bias is not deliberate or conscious, but it does exist.
When we say “unconscious bias”, we mean the biases that we do not even know that we have. It happens when people are not aware of the reasons why they are biased.
People have various kinds of unconscious biases.
Affinity Bias
This is the tendency to favor people who share your own characteristics. For example, if you have a physical disability, you might be biased in favor of other people with physical disabilities. If you are the type of person who is constantly feeling bad about the state of the world, you might be biased in favor of people who feel the same way.
Gender Bias
People often have a bias against people of other genders. This bias is called gender bias. For example, if you are a woman and you work in a male-dominated environment, you might be biased in favor of women. If you are a woman and you are constantly trying to get people to like you, you might be biased in favor of other women.
Race Bias
People often have a bias against people of other races. This bias is called race bias.
If you are a black person and you are constantly trying to get people to like you, you might be biased in favor of other black people.
Class Bias
People often have a bias against people of other social classes. This bias is called class bias. If you are a middle-class person and you work in a low-class environment, you might be biased in favor of other middle-class people. A similar bias is found in people favoring people of the same country over foreigners which is called Nationality Bias People often have a bias against people of other nationalities.
