The first trait theory was proposed by psychologist Gordon Allport in 1936. Allport found that one English-language dictionary contained more than 4,000 words describing different personality traits. He categorized these traits into three levels: cardinal, central, and secondary.
Trait theorist Raymond Cattellreduced the number of main personality traits from Allport’s initial list of over 4,000 down to 171. He did so primarily by eliminating uncommon traits and combining common characteristics. Next, Cattell rated a large sample of individuals for these 171 different traits. Using a statistical technique known as factor an...
British psychologist Hans Eysenckbelieved that personality has a biological basis, developing a model of personality based on just three universal traits.
Both Cattell’s and Eysenck’s theories have been the subject of considerable research. This has led some theorists to believe that Cattell focused on too many traits, while Eysenck focused on too few. As a result, a new trait theory often referred to as the "Big Five" theory emerged. This five-factor model of personality represents five core traits ...

While trait theory has an objectivity that some personality theories lack (such as Freud’s psychoanalytic theory), it also has weaknesses. Some of the mos...

What is most important to understand is that everyone has different personal...
