Selective perception, projection, stereotyping, the halo effect, and the effect of contrast are common shortcuts people use to form impressions of others that can lead to flawed perceptions. Selective perception involves only noticing certain things based on one's own interests and experiences. Projection is attributing one's own characteristics to others. Stereotyping judges people based on their group membership. The halo effect forms an overall impression based on a few qualities, and the effect of contrast assesses people by comparing them to others. To avoid biases from these shortcuts, one should seek diverse perspectives, be aware of projecting, avoid stereotyping, judge people on their own merits, and not compare them to others.
