Self-efficacy
The belief that your own actions can make a difference.
Self-efficacy is the belief that you can handle a task or situation through your own effort. It describes a person's own assessment of their capability, not its actual level. This expectation helps decide whether people take on a challenge, how long they persist, and how they interpret setbacks.

An expectation about your own ability in a specific situation.
Not general self-confidence and not optimism. It is domain-specific: high in negotiation and low in delegation is entirely possible.
It determines whether you start, whether you keep going, and how you explain failure.
Origin and research
The psychologist Albert Bandura introduced the concept in 1977 as the core of his social cognitive theory. His central claim: people act according to their assessment of their abilities, and that assessment often differs from the abilities themselves. Four sources feed that assessment, in descending order of influence: their own mastery experiences, observing others, encouragement from outside, and how they interpret their own physical reactions.
Since then, self-efficacy has become one of the best-supported constructs in psychology. It predicts performance, persistence, and health behavior across domains, and it can be trained, because its most important source is a person's own experience.
For high performers
In leadership, self-efficacy usually shows up as a small decision: whether you hold the difficult conversation today or push it to next week. People with a long string of successes tend to overestimate their reach; people digesting a defeat tend to underestimate it. Both distort.
The sober path: record successes as experience rather than dismissing them as luck. And tie setbacks to what you will do differently next time, not to who you are. Bandura calls this the most important source of all: your own remembered experience.
Distinctions
vs. Self-confidence
Self-confidence is general and stable. Self-efficacy refers to a specific task and can vary widely from one domain to another.
vs. Locus of control
Locus of control asks whether outcomes depend on your actions at all. Self-efficacy asks whether you can pull off the required action.
vs. Realistic optimism
Optimism expects good outcomes. Self-efficacy expects to be able to contribute to them. Each can exist without the other.
Frequently asked questions
Can self-efficacy be trained?
Yes. The strongest source is your own mastery experience. Breaking tasks into achievable steps and consciously registering each completed step builds self-efficacy systematically. What matters is that the success is consciously noticed.
How do I recognize low self-efficacy?
By avoidance. Tasks get postponed, challenges get sidestepped, setbacks get read as proof of personal inadequacy. With high self-efficacy, a setback is more likely to be read as a sign of insufficient effort or a wrong strategy.
Is high self-efficacy always good?
No. Inflated self-efficacy leads to underestimating risk and underpreparing. What works is an assessment slightly above your actual ability: high enough to start, realistic enough to learn.
