Let’s learn about bias

We all prefer one thing, group or person over another — even if we don’t think we do

Racism is a form of bias — a belief that one group is better or superior.

Many people would like to believe that they treat all people equally. But often that simply isn’t true. People can be biased — preferring one group of individuals over another. Many times, that bias is implicit — meaning the people who are biased don’t know they are.

Sometimes a bias can be innocent. Maybe you prefer the color blue over the color red. That’s okay. Even bedbugs have favorite colors.

When bias is in favor of one group of people over another, though, it can lead to great harm. Some biases, such as racism and sexism, can even impact someone’s physical health and increase signs of depression. Many of these biases arise out of stereotypes — simplified beliefs that may not be true. But biases can be changed, with learning and understanding and listening.
