A Framework for Addressing Group Judgment Biases with Group Technology

Lai-Huat, Lim and Bensabat, Izak

ABSTRACT: Systematic biases have been found in both individual and group judgments, calling for research into debiasing approaches. Although individual debiasing has been studied to some extent, no such effort exists for group debiasing. This paper advocates the use of group support systems (GSS) for group debiasing and presents a theoretical perspective on how this debiasing may be achieved. Special attention is paid to two important judgment biases: representativeness bias and availability bias. A research model is developed from which propositions are derived.

Key words and phrases: availability bias, debiasing, decision-making bias, group support systems, representativeness bias
