| dc.description.abstract | Skilled decision making is an acquired skill that often leads to better life outcomes (e.g. wealth, health, and happiness) (Cokely et al., 2012; 2018). There is a growing body of literature centered on Bias Blind Spot which states that individuals are biased in self-evaluation. On average, people inaccurately perceive themselves as better decision makers than the public, regardless of individual differences (Pronin Lin, & Ross, 2002; Scopelliti et al., 2015; West, Meserve, & Stanovich, 2012). Given that skilled decision makers tend to better understand themselves compared to others, it is hypothesized that those who are more numerate are less biased and know it (Kruger & Dunning, 1999; Ghazal, Cokely, Garcia-Retamero, 2014). To test this, 309 participants answered high fidelity tests of decision making skill and completed a newly formed bias blind spot measure that includes representative questions of both social and cognitive biases. Results suggest that skilled decision makers tend to be better than average on decision tasks and their confidence reflects accuracy in their performance. Findings indicate that quality of self-evaluation may be a function of general decision making skill. Implications for training and self-regulated learning are discussed. | en_US |
