Gender bias refers to the unequal treatment or perception of individuals based on their gender. This bias can manifest in various forms, such as stereotypes, discrimination, and unequal opportunities in areas like the workplace, education, and social settings. It often leads to the reinforcement of traditional gender roles, where certain behaviors and attributes are deemed appropriate for one gender over another. This bias can affect both men and women, but it often disproportionately impacts women, leading to challenges such as the gender pay gap and underrepresentation in leadership positions. Addressing gender bias is essential for promoting equality and ensuring that everyone has the same opportunities, regardless of their gender identity.
