Abstract
In the decade following Latane and Darley's publication of the discovery that the presence of other people inhibits an individual from intervening in an emergency, numerous researchers have attempted to replicate this finding, extend its range of applicability, and determine what boundary conditions limit it. In the present article, we review both published and unpublished research, with special attention to the nature of the precipitating incident, the ambiguity of the helping situation, laboratory versus field settings, characteristics of the subjects, of the victim, and of other bystanders, and the amount and kinds of communication among bystanders. We conclude that, despite the great diversity of styles, settings, and techniques among the studies, the social inhibition of helping is a remarkably consistent phenomenon; but we identify some conditions under which the effect can be weakened or eliminated. Finally, we explore the implications of these findings for assessing and increasing a victim's likelihood of receiving help. Some 10 years have passed since Latane and Darley (1970) published their monograph reporting the results of a program of research on bystander intervention in emergencies. This research provided strong support for the general proposition that "the presence of other people serves to inhibit the impulse to help " (p. 38), Their work elicited a good deal of interest, and it has stimulated a large amount of subsequent research in this area. We see at leas…

“For example, just as the presence of others inhibits bystander intervention in emergencies (Latané & Nida 1981), anonymity increases the incidence of free riding—that is, attempting to benefit from the group’s actions without personally contributing to the public good (Kerr & MacCoun 1985).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
