The test consists of a list of terms, each of which is an adjective relating to a personality trait. (For example, the list might begin with "accepting", "adaptable", "bold", "brave", "calm", "cheerful", and "complex".) A subject will select a few of these terms which he feels describes himself best. Each of his peers will then select a few terms which that person feels describes the subject best.
