Lewis R. Goldberg is an American personality psychologist and a professor emeritus at the University of Oregon. He is closely associated
[1] with the lexical hypothesis that any culturally important personality characteristic will be represented in the language of that culture. This hypothesis led to a five factor structure of personality trait adjectives (which he dubbed the Big 5).[2][3][4] When applied to personality items this structure is also known as the five-factor model (FFM) of personality. He is the creator of the International Personality Item Pool[5][6][7](IPIP),[8] a website that provides public-domain personality measures.
