Our cultural identities and our personalities affect our perceptions. Sometimes we are conscious of the effects and sometimes we are not. In either case, we have a tendency to favor others who exhibit cultural or personality traits that match up with our own. This tendency is so strong that is often leads us to assume that people we like are more similar to us than they actually are. Knowing more about how these forces influence our perceptions can help us become more aware of and competent in regards to the impressions we form of others.
