There are several types of unconscious bias that are often at play without our conscious awareness, some examples are:
Affinity Bias – This is a tendency to like and prefer people who are similar to yourself. People who are like each other, like each other!
Attribution Bias – A tendency to attribute success and failure differently for different groups of people.
Confirmation Bias – This is where you look for confirmation that your existing ideas and assumptions on a group of people are correct.
Halo Effect – This is where you assume that someone is an overall good person simply because you like them.
Perception Bias – This is where you believe one thing as fact for an entire group of people based on misinformed stereotypes.
Group Think – This is where you try overly hard to fit into an existing culture or group which can, in turn, suppress your unique take on things and potential ideas. This can result in a loss of personal identity and lost creativity.
