Abstract
Using a decision-rule to predict academic or job performance has attracted scientists and practitioners’ interest. Following a decision-rule’s result or not, is based either on the holistic approach (decisions are made with the use of intuition and personal judgment) or the mechanical approach (decisions are made with the use of a decision-rule’s result). Research evidence has demonstrated that using a decision-rule’s result provides more accurate predictions than individuals’ predictions and should be preferred. However, individuals tend to avoid using results of decision-rules, which is known as algorithm aversion. A cognitive process, namely intuitive thinking style, might be related to algorithm’s aversion persistence. Research on people’s intuitive thinking style has displayed a preference for intuitive-based hiring. A compromising solution, between research suggestion and practitioners preferred way of selection, is to provide the option of deviation from the decision-rule’s result. However, this has the consequence of less accurate predictions. In this mixed-method study (N = 22), using a correlational analysis we studied whether people with high scores on intuitive thinking style would be more likely to deviate from the decision-rule's result (Hypothesis 1) and to make less accurate predictions, due to that deviation (Hypothesis 2). We found statistical support for Hypothesis 1, but not for Hypothesis 2. Using thematic analysis, we examined why people deviate from the decision-rule’s result. We were only able to identify individuals’ thinking patterns related to the use of the decision-rule. Implications and future directions are also discussed. Keywords: decision-making, intuitive thinking style, algorithm aversion, performance prediction
