Attribution Theory

In 1958, Austrian psychologist Fritz Heider published The Psychology of Interpersonal Relations and proposed something that sounds obvious until you realise how badly most people get it wrong: humans are constantly constructing causal explanations for the behaviour they observe. Not occasionally. Not when prompted. Constantly. Every time a colleague misses a deadline, a competitor launches a product, a candidate stumbles in an interview, or a CEO resigns — the mind automatically generates an explanation for why it happened. Heider called this process attribution, and he identified the two channels through which every explanation flows. Internal attribution locates the cause inside the person — their character, talent, motivation, intelligence. External attribution locates the cause outside the person — their circumstances, incentives, constraints, luck. The employee was late because they're careless (internal) or because the subway broke down (external). The startup failed because the founder lacked grit (internal) or because the market collapsed (external). Every causal explanation you construct about another person's behaviour passes through one of these two channels — and the channel you default to determines how you hire, fire, invest, manage, and judge.

Heider's framework was expanded by Harold Kelley in the 1960s and 1970s into a more precise model. Kelley's covariation principle identified three dimensions people unconsciously evaluate when deciding whether to attribute behaviour internally or externally: consistency (does this person behave this way every time?), distinctiveness (does this person behave this way only in this situation?), and consensus (does everyone behave this way in this situation?). When consistency is high, distinctiveness is low, and consensus is low — "she's always like this, in every context, and nobody else acts this way" — the mind attributes the behaviour to the person. When all three point outward — "this only happened once, only in this context, and everyone else had the same problem" — the mind attributes it to the situation. Kelley's model describes the calculus the mind runs automatically, in milliseconds, on every piece of social behaviour it observes.

Bernard Weiner extended attribution theory in a different direction — toward achievement and motivation. Weiner's model added two dimensions beyond locus (internal vs. external): stability (is the cause permanent or temporary?) and controllability (could the person have changed it?). These dimensions determine emotional and behavioural responses. Attributing a colleague's failure to low ability (internal, stable, uncontrollable) produces pity and lowered expectations. Attributing it to low effort (internal, unstable, controllable) produces anger and punishment. Attributing it to task difficulty (external, stable, uncontrollable) produces sympathy and adjusted targets. Same failure, radically different organisational response — determined entirely by which causal story the manager constructs.

The practical consequence is severe: attribution is not a passive observation. It is a construction that determines action. The attribution a manager makes about an employee's underperformance dictates whether they coach, reassign, or terminate. The attribution an investor makes about a portfolio company's missed targets dictates whether they double down, hold, or exit. The attribution a board makes about a CEO's strategic pivot dictates whether they grant runway or begin a succession search. In each case, the causal story — not the underlying data — drives the decision. And the causal story is generated by the same automatic, largely unconscious process that Heider described in 1958: the mind reaches for an explanation, finds one that feels coherent, and stops looking.
