Are you a good judge of character? How quickly can you “size someone up?” Interestingly, research shows that many people are surprisingly accurate at predicting how an interaction with someone will unfold based on initial impressions. Fascinating research has also been done on the ability of people to make a judgment about a person’s competence after as little as 100 milliseconds of exposure to politicians’ faces. Even more surprising is that people’s judgments of competence, after exposure to two candidates for senate elections, accurately predicted election outcomes.^[1] In short, after only minimal exposure to a candidate’s facial expressions, people made judgments about the person’s competence, and those candidates judged more competent were people who actually won elections! As you read this section, keep in mind that these principles apply to how you perceive others and to how others perceive you. Just as others make impressions on us, we make impressions on others. We have already learned how the perception process works in terms of selecting, organizing, and interpreting. In this section, we will focus on how we perceive others, with specific attention to how we interpret our perceptions of others.
