Defensive Attribution Hypothesis
The tendency to assign or withhold blame for an accident in a way that protects the observer from feeling vulnerable to a similar misfortune, varying with the accident's severity and the observer's perceived similarity to those involved.

The connective logic
The proposed mechanism is anxiety reduction about personal vulnerability. Walster's version: believing a severe accident was controllable (someone's fault) reassures the observer it can be averted and won't strike randomly. Shaver's refinement adds two motives that can pull in opposite directions — (1) harm-avoidance: blaming a perpetrator distances the observer from the victim's fate ('I won't be harmed like that'); and (2) blame-avoidance: when the observer resembles the perpetrator, blaming them implies 'I could cause this too,' so they instead exonerate the similar perpetrator. Which motive dominates depends on personal and situational relevance/similarity.
The severity-blame link is also explained without any defensive motive: the just-world hypothesis (Lerner) attributes victim-blaming to a need to believe the world is fair; the culpable-control / counterfactual-availability and 'outcome bias' accounts hold that severe outcomes simply make negligent causes more salient or are weighted more heavily, a cognitive rather than motivational process. Nogami and Streufert, and Fincham & Jaspars, debated whether causal versus moral responsibility distinctions salvage the hypothesis (Fincham 1984, Eur. J. Soc. Psychol., DOI 10.1002/ejsp.2420140209). Robbennolt (2000) found the severity-responsibility relationship holds across methodologies, which is more consistent with a general cognitive outcome-severity effect than a specifically defensive one.
Case status — replication
Partly held
The two halves of the hypothesis have different track records. The pure severity-increases-blame claim is weak and inconsistent: Walster's own 1967 follow-up failed to replicate it, many studies found no effect, and Burger's (1981) meta-analysis of 22 studies found only a 'statistically significant but weak' severity-blame tendency. The similarity/relevance interaction Shaver added is better supported — Burger reported evidence for the predicted negative similarity-responsibility relationship, where similar observers exonerate similar perpetrators. Robbennolt's (2000) meta-analytic review confirmed a positive severity-responsibility relationship that is consistent in direction across methods but varies in strength by judgment type, and is compatible with non-defensive cognitive explanations. Net: a real but small and theoretically contested effect, not a robust law.
How to break the chain
Judge the decision, not the outcome: hold severity constant by asking 'would I assign the same blame if this exact conduct had caused minor harm?' and 'would I judge a person I identify with the same way?' Pre-commit to process-based standards before knowing the outcome, and separate causal contribution from moral blame — the explicit distinction (Nogami/Streufert; Fincham) that the severity effect tends to blur.
Feigenson et al. (1997) found jurors conflated liability with damages and over-weighted severity; Robbennolt's (2000) meta-analysis confirms outcome severity systematically biases responsibility judgments, so debiasing requires deliberately decoupling outcome magnitude from fault.
Catch it in the act
Watch for blame that scales with how badly something turned out, or that flips depending on how much the judge resembles the person at fault. Tells: 'they should have known better' applied harder after a catastrophe than after a near-miss with identical conduct; jurors or investigators harshly faulting an accident victim/operator when the scenario feels distant ('I'd never do that') but excusing a relatable one; quick certainty that a disaster was someone's controllable error rather than bad luck. The giveaway is that the severity of the outcome, not the quality of the decision, is driving the verdict.
