Group decision making: How you frame the question determines what you find.

Though not arguing against the practical value of group decision making per se, R. S. Tindale and J. R. Larson (see record 1992-19783-001) used data from computer simulations and an 8-group replication study as a basis for questioning the validity of the findings reported by the present authors (see record 1990-04483-001). The authors show that Tindale and Larson's application of computer simulations is suspect, that the replication-study data is so limited that its significance is questionable, that its operational definition of an assembly bonus effect is restrictive to the point that it has little meaning in real-world settings, and that claims with respect to the performance of ad hoc laboratory groups are inflated and misleading.
