Attribution theory shows how we infer single traits on the basis of behavior. Sometimes our inferences aren't really justified by the data but that doesn't seem to stop us. In fact research on what are called "implicit personality theories" shows that once we infer one trait we are likely to infer more, sometimes many more . An "implicit personality theory" is simply a person's ideas about what traits are connected to what other traits. We all have these ideas or theories , and they come into play once we're inferred and initial trait. As the word "implicit" implies, we are often unaware of these processes
