Lesson 1 – The Anatomy of an Explanation

Developed by psychologist Bernard Weiner, Weiner’s Three Dimensions describe the structural framework people use to categorize the perceived causes of their successes and failures. How an event is categorized across these three dimensions determines an individual’s emotional response, future expectations, and motivation to act.

1. Locus of Causality (Location)

Refers to whether the cause of an outcome originates inside or outside the individual.

• Internal: Causes that come from within the person, such as effort, innate ability, skill, or mood.
• External: Causes that originate from the environment or outside forces, such as task difficulty, luck, weather, or actions of others.

2. Stability (Duration)

Refers to whether the cause is permanent or changes over time.

• Stable: Causes that are relatively fixed or permanent, such as baseline task difficulty or innate intelligence.
• Unstable: Causes that fluctuate and can vary from moment to moment, such as temporary effort, mood, fatigue, or luck.

3. Controllability (Agency)

Refers to whether the cause can be actively influenced or altered by the individual.

• Controllable: Factors within an individual’s direct power to change, such as preparation, study strategy, dedication, or execution.
• Uncontrollable: Factors outside direct individual control, such as natural aptitude, weather, or random external events.

Matrix of Common Attributions

Attribution	Locus	Stability	Controllability	Psychological & Behavioral Impact
Effort / Strategy	Internal	Unstable	Controllable	Promotes resilience; failure leads to strategic adjustment and problem-solving.
Ability	Internal	Stable	Uncontrollable	Success boosts confidence; failure risks learned helplessness if seen as low aptitude.
Task Difficulty	External	Stable	Uncontrollable	Sets baseline expectations for future attempts on similar tasks.
Luck / Chance	External	Unstable	Uncontrollable	Creates unpredictability; offers no reliable basis for future planning.

Psychological Impact of the Dimensions

• Expectancy Shifts (Stability): Attributing a setback to a stable factor (e.g., “I’m bad at math”) creates an expectation of repeated failure in the future, whereas attributing it to an unstable factor (e.g., “I used the wrong strategy”) leaves future expectations open to improvement.
• Behavioral Action (Controllability): Attributing outcomes to controllable factors increases perceived personal agency, boosts self-efficacy, and fosters sustained persistence after a failure.
