Type A and Type B personality theory

Type A and Type B personality theory is a theory that describes two common, contrasting personality types — the high-strung Type A and the easy-going Type B — as patterns of behavior that could either raise or lower, respectively, one's chances of developing coronary heart disease. It was originally published in the 1950s. Though it has been widely controversial in the scientific and medical communities since its publication, the theory has nonetheless persisted, both in the form of pop psychology and in the general lexicon, as a way to describe one's personality. Such descriptions are still often equated with coronary heart disease or other health issues, and not always as a direct result of the theory.
