Personality is the individual differences in characteristic patterns of behaving, thinking, and feeling. Cattell identifies 16 personality factors while Eysenck tends to believe that there are three super personality factors which are extraversion, neuroticism, and psychoticism. In my opinion, the three super elements cannot be used to determine an individual's personality (Kelland, 2017) . I think the 16 primary factors of personality determine one’s personality more. I believe that all the 16 primary factors are incorporated in the three super factors. The super factors are still the essential dimensions of personality but will be more useful when broken down into the sixteen super factors.
The trait theory that is most effective in understanding personality is Cattell's theory. This is because it goes into detail and considers a lot of facts in determining one’s personality. Cattell’s theory looks into 16 primary factors that Cattell believed were relevant in determining the traits of any individual. She used the Factor Analysis to come up with the 16 primary factors. Cattell found that to get an unbiased measure of personality, and there must be a concept of the subject's personality sphere which is the subject’s total behavior. This could be achieved by taking sample 24-hour time frame in the subject’s life and collecting three kinds of data which are the subject’s life record (L-data), data collected through questionnaires, (Q-data) and the T-data which is data on the subject’s personality provided by objective tests (Cattell, 2007) . These three types of data are then compared. The comparison of these three data would help a psychologist understand someone’s entire personality. If all the three data are well correlated, the analysis of the individual’s personality will be accurate. This theory is the most effective one since it compares three measures.
