Where does Machiavellianism collide?

In personality psychology the word names a measured trait: a stable individual difference in how much a person manipulates others, holds a cynical view of human nature, and treats moral rules as matters of convenience. Christie and Geis's 1970 book Studies in Machiavellianism defined this trait and built the twenty-item Mach-IV questionnaire to score it, taking its name from popular readings of Machiavelli rather than from his actual argument. The referent here is a number attached to a person by a questionnaire, not a doctrine of government set out in a treatise, and it should not be read as endorsing or describing any real programme of statecraft.[1]

Unit

A person's standing on a manipulativeness trait, scored from questionnaire answers

Recovery means

Not applicable

Measured by

The twenty-item Mach-IV scale of agreement with cynical and manipulative statements, and later short forms

In individual-differences and organisational research the word names one leg of the Dark Triad, a compact grouping of three overlapping but distinct aversive personalities: narcissism, Machiavellianism, and psychopathy. Paulhus and Williams's 2002 paper The Dark Triad of personality proposed studying the three together with brief measures, and used the label for a strategic, manipulative, cold interpersonal style that predicts behaviour at work. This construct overlaps heavily with the classic Mach-IV trait, so much that studies often struggle to separate it from psychopathy, but it is framed as one slot in a three-part model rather than as a standalone scale, and it has nothing to do with Machiavelli's political treatise.[2]

Unit

One person's score on the Machiavellian component of a three-part dark personality grouping

Recovery means

Not applicable

Measured by

Brief Dark Triad instruments such as the Dirty Dozen and the Short Dark Triad, alongside the older Mach scales

In political philosophy the word names a normative doctrine of statecraft, not a personality: the argument that a ruler who wishes to keep a state may need to act against ordinary morality when necessity demands it, judging actions by their results for the state. Machiavelli set this out in The Prince, written in 1513 and published in 1532, which analyses how power is won and held rather than how virtue is cultivated. The referent is a contested claim about politics that readers still argue over, and it is a different kind of thing from a trait measured in a person: The Prince advances an argument about government, while the psychological meanings score a disposition in an individual.[3]
