Humans use cognitive shortcuts, or heuristics, to quickly assess and respond to situations and data. When applied inappropriately, heuristics have the potential to redirect analysis of available information in consistent ways, creating systematic biases resulting in decision errors. Heuristics have greater effect in high-pressure, high-stakes decisions, particularly when dealing with incomplete information, in other words, daily medical and surgical practice. This article discusses 2 major categories: cognitive biases, which affect how we perceive and interpret clinical data; and implicit biases, which affect how we perceive and respond to other individuals, and also discusses approaches to recognize and alleviate bias effects.
