Group versus individual performance: Are N + 1 heads better than one?

Abstract: Experimental comparisons of groups and individuals were analyzed on four dimensions: task, process, individual differences, and methodology. A standardized terminology based on Lorge, Fox, Davitz, and Brenner was developed to preserve operational definitions in the comparisons of (a) group versus individual, (b) group versus the most competent individual in an aggregate, (c) group versus pooled responses of an aggregate, and (d) group versus math models of performance. Research supported Steiner's theory of pr… Show more

“…Neben diesen positiven Befunden liegen aber auch Ergebnisse vor, die den postulierten Synergieeffekt in Gruppen bezweifeln (Brown 2000;Hill 1982). Empirisch wurde etwa nachgewiesen, dass die Leistungen von Personen in Gruppen häufig geringer ausfallen als von Personen, die allein für die Erstellung eines Produktes verantwortlich sind (Arnscheid, Diehl und Stroebe 1997;Shepperd 1993;Shepperd und Taylor 1999).…”

“…Empirical results show that groups are often more accurate than average individuals (Garcia-Retamero, Takezawa, & Gigerenzer, 2008;Hastie & Kameda, 2005;Hill, 1982;Kameda & Nakanishi, 2002;Kerr & Tindale, 2004). For instance, even when individuals' quantitative judgments are systematically biased, the performance of the average 1 The resulting (sample-based) cue ordering when using the validity algorithm should not be confused with the ecological validity ordering, as Dougherty, Franco-Watkins, and Thomas (2008) did.…”

“…Although it is true that, as a rule, group decisions are better than individual decisions (Hill, 1982), especially in highly complex and uncertain situations, it must also be taken into account that the larger BoDs have to face such problems as the impairment of the decisionmaking process, the hazy nature of the individual members' responsibilities, and a certain detached attitude vis-à-vis the facts handled by the management. According to this viewpoint, and based on group dynamics theories, an excessively large board could condition decision-making and there might be communication and organization problems, also in consequence of the formation of internal factions or coalitions.…”
