Let’s begin our exploration here by trying to understand the purpose of bias. We go out in the world every day and make decisions about what is safe or not, what is appropriate or not, and so on. This automatic decision making is what psychologist Joseph LeDoux has suggested is an unconscious “danger detector” that determines whether or not something or someone is safe before we can even begin to consciously make a determination.4 When the object, animal, or person is assessed to be dangerous, a “fight or flight” fear response occurs.
