Primes¶
- Bystander Effect
- The Bystander Effect is a group-behavioral pattern in which (1) an event calls for intervention (help, correction, escalation), (2) multiple potential intervenors are co-present and mutually aware, (3) each potential intervenor's subjective probability of acting decreases as the number of other potential intervenors rises, because responsibility is diffused across the set, the absence of others' action is read as informational evidence that no action is needed (pluralistic ignorance), and the cost of publicly misjudging the situation is non-trivial (evaluation apprehension), and (4) the group-level result is that as the pool of potential helpers expands, the probability that anyone acts can decline rather than rise.
This sourceFoundational monograph formalizing the three mechanisms (diffusion of responsibility, pluralistic ignorance, audience inhibition) and generalizing across multiple emergency types.

- Pluralistic Ignorance
- In the bystander effect, part of the failure to intervene in an ambiguous emergency is pluralistic ignorance: each witness, seeing others remain calm, infers from that calm that the situation is not really an emergency, when in fact each privately suspects it is and is reading the others' (identically motivated) inaction as information.
This sourceIdentifies pluralistic ignorance in the bystander effect — witnesses reading others' calm as evidence the situation is not an emergency.

- Responsibility Diffusion
- This mechanism operates because individuals psychologically attribute responsibility to others when observers or decision-makers are plural, eroding the sense of personal obligation that drives action, an attribution dynamic Latané and Darley (1970) document across multiple emergency paradigms.

Mechanisms¶
- RACI or Decision Participation Matrix
- The pathology it exists to guard against is diffusion of responsibility — the more people nominally share a duty, the less any single person acts on it
This sourceExplains diffusion of responsibility: as more bystanders share an emergency, each feels less personal responsibility and intervention becomes less likely.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 4 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
