The Effects of Group Size on Cognitive Effort and Evaluation

Petty, Richard E., Harkins, Stephen G., Williams, Kipling D., Latane, Bibb·1977·Personality and Social Psychology Bulletin

Abstract

Students rated a poem and an editorial believing that they alone were responsible, that they were one of four persons responsible, or that they were one of sixteen persons responsible for evaluating the communications. As predicted, group mem bers reported putting less effort into the assessment than indi viduals, and this diffusion of effort followed an inverse power function. In addition, individuals evaluated the communications more favorably than persons who thought they shared the evalu ation responsibility.

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.
