Abstract

It has long been appreciated that humans behave irrationally in economic decisions under risk: they fail to objectively consider uncertainty, costs, and rewards, and instead exhibit risk-seeking or risk-averse behavior. We hypothesize that poor estimates of motor variability (influenced by motor task) and distorted probability weighting (influenced by relevant emotional processes) contribute to characteristic irrationality in human movement decisions. SUMMARY: We propose that irrational movement decisions under risk result from inaccurate variability estimation and threat-induced distortions in probability weighting.
