Personality-and-politics research divides into psychobiography, typologies, and aggregative analyses

Evidence

Most research on personality and politics falls into one of three broad categories: (a) psychological case histories (or psychobiographies) of individual political actors, (b) typological studies focusing on the classification of political actors, and (c) aggregative analyses that examine the collective effects of individuals on the functioning of political institutions and vice versa (Greenstein, 1969). — John T.
