Demology, or the study of human behavior, has isolated three key types: aggressive behavior, passive behavior and assertive behavior. Each individual's proclivity for any one of these behaviors depends largely upon their personal attitudes, that is, as to the acceptability or desirability of that behavior. These attitudes, in turn, are often closely related to their social or cultural context.
Human behavior is a complex topic that some psychologists have tackled by organizing into comprehensive lists of personality types.
David Keirsey, for example, has outlined the following four temperaments, complete with their associated behaviors:
- Guardian: cooperative, dutiful, obedient and respectful
- Idealist: conscientious, ethical, goal-driven and socially-minded
- Artisan: pragmatic, sensory, flexible about rules and ethics
- Rational: efficient, goal-driven, quite comfortable with breaking rules and conventions
