Abstract
Cognitive Bias and the Treatment of Complex Illnesses: A Reflection on Substance Use Disorder and Long COVID. Physicians use anchoring and confirmation bias every day to make snap decisions about patient care. However, in the case of poorly understood complex illness, cognitive bias can lead to poor outcomes for the patient. This article explores how recognizing and overcoming cognitive bias leads to increased personal career satisfaction, and improved patient outcomes. In an era where health disparities are increasingly recognized, and in the post-COVID era in particular, there's a need to recognize cognitive bias against complex illnesses such as Long COVID and Chronic Fatigue Syndrome. It may even be a moral imperative.
