Answer to Question 2
Cattell believed traits must be determined empirically. Cattell collected many different types of data, including lexical data, self-report questionnaire data, observer ratings, and objective behavioral data. He factor analyzed these various kinds of data and found that 16 dimensions constituted the primary traits in personality. In contrast, Eysenck believed theorists should begin with well-developed ideas about the underlying variables they believe to be the most important, and then set out to measure these variables well. Eysenck based his ideas on the four types proposed by Hippocrates and Galen. He argued that these four types could be created by combining high and low levels of two supertraits called introversion-extraversion and emotionality-stability.
