1. Awareness of perceptual bias
One of the most obvious ways to reduce biases is by knowing they exist. Diversity training can also help to reduce biases.
2. Improving self-awareness
Helping people become more aware of biases in their decision making and behaviour, through procedures such as the IAT (Implicit Association Test), which detects subtle race, age and gender bias by associating positive and negative words with specific demographic groups.
3. Meaningful interaction
Based on the contact hypothesis, a theory stating that the more we interact with someone, the less prejudiced or perceptually biased we will be against that person.
