In the field of personality psychology, Machiavellianism is a personality trait centered on manipulativeness, callousness, and indifference to morality. Though unrelated to the historical figure or his works, the trait is named after the political philosophy of Niccolò Machiavelli, as psychologists Richard Christie and Florence Geis used edited and truncated statements inspired by his works to study variations in human behaviors. Their Mach IV test, a 20-question, Likert-scale personality survey, became the standard self-assessment tool and scale of the Machiavellianism construct. Those who score high on the scale (High Machs) are more likely to have a high level of deceitfulness and an unempathetic temperament.

It is one of the dark triad traits, along with narcissism and psychopathy.
