"Raymond Cattell is an influential personality researcher whose work started in the 1920s and spanned many decades. Using a statistical method called factor analysis his research found 16 primary traits underlying human personality. He constructed a test called the 16pf to measure those traits. He later found those traits aligned with five factor personality theory (the big five)."
