who came up with big 5 personality traits
Big Five personality traits The initial model was advanced by Ernest Tupes and Raymond Christal in 1961,[12] but failed to reach an academic audience until the 1980s. In 1990, J.M. Digman advanced his five-factor model of personality, which Lewis Goldberg extended to the highest level of organization.[13] These five overarching domains have been found to contain and subsume most known personality traits and are assumed to represent the basic structure behind all personality traits.[14]
The Big Bang Theory The show is primarily centered on five characters living in Pasadena, California: Leonard Hofstadter and Sheldon Cooper, both physicists at Caltech, who share an apartment; Penny, a waitress and aspiring actress who later becomes a pharmaceutical representative and who lives across the hall; and Leonard and Sheldon's similarly geeky and socially awkward friends and co-workers, aerospace engineer Howard Wolowitz and astrophysicist Raj Koothrappali. The geekiness and intellect of the four men are contrasted for comic effect with Penny's social skills and common sense.[5][6]
