A tendency to assume that people with one positive attribute (e.g., who are physically attractive) also have other positive traits.
For example, for each point increase on a 1 (homely) to 5 (strikingly attractive) scale of attractiveness, people are likely to earn an average of about $2,000 more a year.
For instance, attractive defendants are less likely than unattractive defendants to be found guilty when accused of a crime (Efran, 1974), and when they are found guilty, they are given lighter sentences (Stewart, 1980).
Attractive people are generally more outgoing, popular, and socially skilled , but they are not higher in self-esteem, life satisfaction, mental health, sensitivity, or intelligence. First, it turns out that people are often mistaken in their perceptions of how physically attractive other people think they are. So some people think they are less physically attractive than they really are. Second, no one wants to be valued only because of their looks or any other single characteristic. Highly attractive people may sometimes wonder if that's the only reason people compliment them or care for them.
When we see an attractive person, we assume all kinds of good things and become motivated to impress him. As a consequence, we are likely to be more pleasant and charming with him. Because we treat him in a more accepting and encouraging manner, he is likely to respond in kind.
