Document Summary
Five broad factors developed through lexical and statistical approaches. Lexical hypothesis: look for traits that have most words and are most universal. The things that are important in our daily lives, we have more words to represent them. Factor analysis: other personality tests tend to fit the big five groups. More complex than they seem at first. Anxiety, angry hostility, depression, self-consciousness, impulsiveness, vulnerability. Warmth, gregariousness, assertiveness, activity, excitement- seeking, positive emotions. Trust, straightforwardness, altruism, compliance, modesty, tender- mindedness. When translated to other languages, four or five factors appear. When starting with other languages, some overlap but not one-to-one correspondence. Based on doubt about whether it is valid to compare people quantitatively on same trait dimensions. Important differences between people may be qualitative. Challenges: find divisions that distinguish different types; show differences are. Is it useful to think about people in terms of types? qualitative. Makes it easier to think about how traits within a person interact with each other.
