Raymond Cattell thought that clinical personality observations were not a scientific base for understanding or classifying personality traits. He utilized the Inductive Method to develop his own Pesonality Theory. Cattell's Personality Theory, described as a trait theory which was formulated to evaluate the motivation, cognitive and personality abilities that distinguishes one person from another. He defines personality as "that which permits a prediction of what a person will do in a given situation". Cattell, however later on, does add that personality can encompass what is observable and concrete and what may only be inferred.
Cattell identified 16 personality traits, later known as the 16 Personality Factor Questionnaire, which are used to measure behviors, in different forms of data reporting.
