What Is the Locus of Control?
When something goes wrong, it’s natural to cast blame on the perceived cause of the misfortune. Where an individual casts that blame can be related, in many cases, to a psychological construct known as locus of control.
Locus of control refers to the degree to which an individual feels that a sense of agency in regard to his or her life. Someone with an internal locus of control will believe that the things that happen to them are greatly influenced by their own abilities, actions, or mistakes. A person with an external locus of control will tend to feel that other forces—such as random chance, environmental factors, or the actions of others—are more responsible for the events that occur in the individual's life.
Like other constructs in personality psychology, locus of control falls on a spectrum. Genetic factors may influence one’s locus of control, as well as an individual’s childhood experiences—particularly the behaviors and attitudes modeled by their early caregivers.
Researchers have identified several areas in which one’s locus of control appears to affect outcomes, including education, health, and civic engagement. Overall, such research has generally suggested that those with a more internal locus of control are more successful, healthier, and happier than those with a more external locus.
The Relationship Between Self-Efficacy and Locus of Control
Another psychological concept related to locus of control is that of self-efficacy. Self-efficacy, as described by psychologist Albert Bandura, refers to one’s belief that they are able (or not able) to accomplish tasks and achieve their goals.
Though people with high self-efficacy also typically have a more internal locus of control, the two measures are not perfectly correlated. Someone, for example, may feel like they have the power to influence their own health while simultaneously feeling like they lack certain skills—such as cooking healthy meals—that would improve their health (high internal locus of control, but low self-efficacy).
Some research has suggested that one’s self-efficacy can be improved with practice, while locus of control is less easily influenced. There is some evidence, however, that one's locus of control may naturally change with age.
