Differential access to information and anticipated group interaction: impact on individual reasoning.
Two studies examined the impact of relative differences in access to information and anticipated group interaction on individual reasoning. On 2 different reasoning tasks (P. C. Wason's [1966] selection task and D. Kahneman & A. Tversky's [1973] lawyer-engineer problem), participants sensing that they knew more in anticipation of group interaction or knew less when not anticipating interaction were less susceptible to typical cognitive biases demonstrated by these tasks. Study 2 also showed that the effect of these social contexts was contingent on the task presentation format. Thus, knowing more in anticipation of group interaction and knowing less when not anticipating group interaction seemingly compensated for task features that enhance suboptimal reasoning strategies. These results illustrate the importance of the social context in which reasoning is situated and are discussed in terms of cognitive tuning, social comparison, and social motivations.
