There are several strategies leaders can implement to mitigate affinity bias: 1. Structured Interviews: Use standardized questions and evaluation criteria to ensure all candidates are assessed fairly. 2. Diverse Panels: Include diverse team members in the hiring and promotion processes to provide varied perspectives. 3. Bias Training: Offer training programs to help leaders and employees recognize and address their own biases. 4. Blind Recruitment: Remove identifying information from resumes and applications to focus on skills and qualifications. 5. Inclusive Culture: Foster a culture that values and respects diversity through policies, practices, and leadership behavior.
