Which of the following is true about the five-factor model?

A) Few have criticized it for its lack of predictive value.
B) Hypotheses about the origin of the Big Five factors were generated after the results of the research were seen.
C) Trait theorists would be better off focusing their research on the five main traits.
D) It provides the most comprehensive model to explain personality currently in the field.

Hypotheses about the origin of the Big Five factors were generated after the results of the research were seen. This means that the Big Five factors were discovered through empirical research rather than being determined beforehand by trait theorists. The other options are incorrect: A is false because the Big Five factors have been found to have good predictive value, C is a matter of opinion, and D is false because there are other models that have been proposed to explain personality.
