Pooling of Unshared Information in Group Decision Making: Biased Information Sampling During Discussion
Stasser and Titus tested a biased sampling model of group discussion in a simulated political caucus. Participants read candidate profiles whose partial information made the objectively strongest candidate look unfavourable, then discussed as a group. Groups usually backed the candidate members had favoured initially, and recall of candidate traits before and after discussion suggested that discussion kept the distorted impressions in place. Journal of Personality and Social Psychology 48(6), 1467-1478, 1985. No sample sizes or effect sizes are used.
