Leaders can take several steps to identify affinity bias within their organization: 1. Self-Reflection: Encourage leaders to reflect on their own decision-making processes and consider whether they are favoring individuals who are similar to themselves. 2. Feedback Mechanisms: Implement systems where employees can provide anonymous feedback on their experiences and perceptions of bias within the organization. 3. Data Analysis: Regularly review data related to hiring, promotions, and project assignments to identify patterns that may indicate bias.
