Document Summary
Evidence for in-group bias in infancy and childhood. Group processes in decision making and how factors such as the common knowledge. Implicit association test effect, group polarization, and groupthink can lead to poorer decisions. Even young infants and children exhibit in-group and out-group discrimination. In some study, 5-month old kids looked at a person who spoke their mother language (vs. a foreign language) We often have in-group or out-group beliefs that we are not even aware of. These can affect our behaviours, cognition, and emotions in subtle ways. One measure of implicit biases is called the iat. It measures biases that we are unable to report ourselves. These differ from biases that we are unwilling to report ourselves. Group polarization: groups can sometimes make decisions that are more extreme than any member would have made alone. Deindividuation: immersion in a group can cause people to become less concerned with their personal values. Groupthink: groups can sometimes reach consensus too easily.
