Mach-IV Scale

Background

The Mach-IV Scale is a psychological self-report assessment developed by Richard Christie and Florence L. Geis (1970) to measure Machiavellian personality traits. The scale evaluates manipulative attitudes, cynical beliefs about human nature, strategic interpersonal behavior, emotional detachment, and pragmatic morality.

The Mach-IV is one of the most widely used instruments for assessing Machiavellianism in personality and social psychology research. Higher scores may indicate stronger tendencies toward manipulation, interpersonal distrust, strategic deception, and utilitarian decision-making.

Procedure

Read each statement carefully and select the response that best describes your agreement with the statement. Answer honestly and choose the option that most accurately reflects your typical beliefs or attitudes. There are no right or wrong answers.

Participation

This assessment is intended for educational, research, and self-reflection purposes only. It is not intended to provide a formal clinical diagnosis. Results should be interpreted within the broader context of personality functioning and interpersonal behavior.

Scoring & Interpretation

The Mach-IV is scored using a 5-point Likert scale (0 = Strongly Disagree to 4 = Strongly Agree). Total raw scores are calculated by summing all responses, with reverse-scored items (marked with mapping key 1) inverted prior to calculation (e.g., 0 becomes 4, 1 becomes 3, etc.). The total score ranges from 0 to 80, with higher scores representing a greater concentration of Machiavellian traits. Scores are distributed across five distinct sub-scales (Manipulative Tactics, Morality, Cynical View of Human Nature, Distrust, and Pragmatic Beliefs), which are standardized to a 0–100 scale for comparative profiling.
