A prejudice in favour of or against one thing, person, or group. Brains automatically make quick judgments and assessments. They are influenced by our background, personal experiences, societal stereotypes and cultural context. It's not just about gender, ethnicity and other visible diversity characteristics such as height, body weight, names, and many other things can also trigger unconscious bias. Unconscious bias can have a significant influence on our attitudes and behaviours, especially towards other people. It can influence key decisions in the workplace and can contribute to inequality, for example in selection and recruitment, appraisals, or promotion. Understanding unconcious bias is key to understanding the origins of discrimination and inequalities which marginalised people are victim of.
