The rapid increase of individuals from historically marginalized groups, including women and those from underrepresented racial and ethnic backgrounds in medicine (URiM), pursuing careers in the field of medicine has not led to proportional representation among the faculty of medical schools [1, 2]. This disparity can be attributed to the phenomenon of unconscious bias, which refers to hidden biases or prejudices we hold about social groups that influence our thoughts and behaviors without our conscious awareness [3]. Extensive research has revealed the significant impact of unconscious bias on how we evaluate and interact with others [4]. This chapter delves into the nature of unconscious bias and its potential implications for faculty members from diverse social backgrounds. It commences with a comprehensive definition and exploration of the origins of unconscious bias, investigates its effects on the career paths of faculty members, and outlines a range of effective strategies, both at the individual and institutional levels, to counteract its adverse consequences.
