In a partial replication of an earlier study by Wallach and Kogan, group risk taking was examined under conditions of discussion and information exchange. Group size was also manipulated. Unlike the earlier findings, a risky shift occurred in the information exchange condition, where the subjects only revealed to one another the contents of their prior decisions. A stronger risky shift was found when discussion was permitted. Risky shift was more pronounced the larger the size of the group. The extent of risky shift on a decision problem was found to be positively related to the initial level of risk on that problem. The results appear to support Browns value of risk theory of group risk taking more closely than any other theory. Author
