Defensive attribution hypothesis
The Defensive Attribution Hypothesis is a cognitive bias where individuals attribute blame to others in a way that preserves their own sense of safety and self-esteem.
How it works
People are motivated to defend themselves against feelings of vulnerability or fear of being a victim. When observing an event where someone is harmed, particularly if it is accidental, people may assign blame based on their perceived similarity to the victim or the perpetrator. The more similar an individual feels to the victim, the more external factors are blamed, believing the accident could happen to anyone, thus maintaining a sense of personal control and safety.
Examples
- In a car accident, a driver might blame the weather or road conditions if they see themselves as similar to the victim, believing the same could happen to them.
- After hearing about a burglary, a homeowner might blame the victim for not having a security system, thus maintaining a belief in their own safety due to their home’s security measures.
Consequences
This bias can lead to unfair blame assignments and a lack of empathy or support for victims. In legal situations, it might result in biased judgments where defendants and victims are treated unfairly. Socially, it can perpetuate victim-blaming cultures, reducing the support systems necessary for recovery and change.
Counteracting
Awareness and education about this cognitive bias can reduce its effects. Encouraging empathy through storytelling and shared experiences can help people understand situations from different perspectives. Training professionals in legal and social fields to recognize and address their biases can improve decision-making processes.
Critiques
Critics argue that focusing too much on this hypothesis might downplay essential factors that contribute to accidents or criminal acts. Overemphasis may lead to ignoring objective circumstances and prevent thorough analyses of events.

Case Studies
Real-world examples showing how Defensive attribution hypothesis manifests in practice
Context
A mid-sized regional hospital had recently rolled out a new electronic medication administration record (eMAR) system. Leadership was under pressure to show improved safety metrics and avoid regulatory scrutiny.
Situation
A patient on the medical ward received a lethal overdose of a high-risk sedative after a nurse selected the wrong drug option in the new eMAR interface. The incident happened three months after rollout and during a busy overnight shift with limited staffing.
The Bias in Action
Immediately after the event, senior clinicians and administrative leaders emphasized the nurse's failure to double-check the medication, framing the error as an isolated act of incompetence. Discussions and memos highlighted the nurse's training gaps and history of small mistakes, while system factors — confusing dropdown labels, default dosing values in the eMAR, and poor staffing levels — received little attention. By attributing blame to an individual, decision-makers preserved the belief that existing protocols, training programs, and leadership oversight were adequate and that their own professional competence and safety systems were intact.
Outcome
The nurse was suspended and later terminated; the hospital issued a brief statement about individual accountability and made small changes (a reminder email and re-training). No immediate system-wide redesign or independent root-cause analysis was conducted. Six months later the hospital recorded an uptick in near-miss medication events and growing staff turnover; a family filed a malpractice suit that proceeded to mediation.
