ACCURACY DECOMPOSITION AND TEAM DECISION-MAKING - TESTING THEORETICALBOUNDARY-CONDITIONS

The purpose of this study was to examine the implications of accuracy decomposition (D. Gigone & R. Hastie, 1997) for team decision making. Specifically, the authors tested the generalizability of the multileve l theory of team decision making (J. R. Hollenbeck et al., 1995), acro ss various components of accuracy. The authors also tested the general izability of this theory across different levels of staff-member speci alization. Results from a study with 420 individuals in 105 teams demo nstrate that the validity of the multilevel theory generalizes across specialization levels but fails to generalize across different compone nts of decision accuracy. The authors concluded that this theory is be st conceptualized as a theory of achievement accuracy, rather than mea n bias or variability bias.
