The impact of individual expertise and public information on group decision making In this open access book the author concludes that expertise could be the key factor for global and interconnected problems. Experimental results have shown that expertise was a stronger predictor than public information regarding change in behavior and strategy adaption. Identifying non routine problem solving experts by efficient online assessments could lead to less volatile system performance from which all decision makers could potentially profit.
