What is Locus of Control?

The degree to which people believe they have control over outcomes in their lives versus outcomes being determined by external forces like luck, fate, or powerful others.

Last reviewed: February 2026

Quick Answer

Locus of control describes whether you believe outcomes result from your actions (internal) or external factors like luck or powerful others (external).

Scientific Background

Developed by Julian Rotter in 1954. Internal locus of control means believing you influence outcomes; external means believing outcomes are beyond your control. It affects motivation, stress response, and health behaviors.

How to Measure

Assessed through questionnaires asking whether outcomes result from personal actions (internal) or external factors (external). Domain-specific measures exist for health, work, and relationships.

Real-World Implications

  • Internal locus predicts greater achievement, health, and well-being
  • External locus can protect self-esteem but reduces motivation
  • Can be shifted through experience and cognitive restructuring
  • Realistic assessment requires balancing internal and external attributions

Common Misconceptions

  • Internal locus is not always better—some things are genuinely beyond control
  • External locus is not learned helplessness—it's about perceived causation
  • Locus of control is on a spectrum, not either/or
