Harold Kelley’s (1967) Covariation Model of Attribution explains how individuals determine the causes of behaviour by systematically evaluating patterns of information across three dimensions: consensus (whether others behave similarly in the same situation), distinctiveness (whether the individual behaves differently in different situations), and consistency (whether the behaviour occurs repeatedly over time in the same context). By “covarying” these sources of information, people infer whether behaviour is best attributed to internal dispositions (e.g., personality) or external circumstances. Kelley’s work built on earlier attribution work such as Fritz Heider’s (1958) foundational distinction between internal and external causes and influenced later developments by Bernard Weiner (1974, 1985) on achievement motivation and causal dimensions (locus, stability, controllability).

From a Christian perspective, this model resonates with Biblical cautions against premature judgment and the call to consider context and the heart. Jesus’ teaching “Do not judge, or you too will be judged” (Matthew 7:1, NIV) and the recognition that “the Lord looks at the heart” (1 Samuel 16:7) encourage humility in attribution, while passages such as Galatians 6:1–5 emphasise restoration and personal responsibility balanced with compassion, aligning with the model’s attempt to fairly weigh situational and dispositional factors. Theologically, it supports a view of humans as morally responsible yet contextually influenced, reflecting doctrines of sin, grace, and the imago Dei.

The value of Kelley’s work for personal wellbeing lies in reducing cognitive biases such as the fundamental attribution error, thereby fostering empathy, healthier relationships, and better conflict resolution, while at a societal level it promotes more just and nuanced judgments in domains like education, mental health, and criminal justice, contributing to social cohesion and ethical decision-making.
