Different preference sets drive decision making, including preferences at risk, patience, trust, altruism, positive and negative reciprocity, elements that make up a tool called decision acuity. Physicians are decision makers and differences have been seen in their personality characteristics depending on the type of specialty they practice, which may influence their preferences. To assess whether decision-making is different between medical specialties, 2 groups of doctors (residents of surgical vs. non-surgical specialties) were taken and surveys were applied with the tasks of Falk et.al 2018, to create the acuity index of decision. The analysis to establish differences was done through linear regressions and Bayesian regressions. With the linear regressions, patience was a virtue and negative reciprocity a defect in the surgical group with statistical significance; while with the Bayesian regressions, patience, optimal risk, positive reciprocity were more likely as virtues, and negative reciprocity and lack of altruism as defects in surgical specialties, and a better acuity index of decision was more likely in the participants related to surgical specialties.
