IT Support for Reducing Group Judgment Biases

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 parallel effort exists for group debiasing. This paper advocates the use of group support systems (G&S) for group debiasing and presents a theoretical perspective on how the impact may be achieved. Special attention is paid to two important judgment biases: representativeness bias and availability bias. A research model is developed, based on which propositions are derived.
