Bias is bad for productivity. Here’s an overview of a study that came out in July 2017. The findings are that perceptions of bias have a negative impact on idea-sharing and job commitment. “Of employees who experienced bias, 34% reported withholding ideas or solutions in the last six months and 48% said they looked for a new job while at their current job during the same time period.”
Perceptions of implicit bias are reduced by an inclusive environment. “Employees were 64% less likely to perceive bias at companies with diverse leaders, 87% less likely when they had inclusive leaders, and 90% less likely when they had sponsors.”
The methodology was to compare self-assessments of employee potential to those employees’ estimates of how they would be rated by their manager. Larger gaps were interpreted as an indicator of bias. There’s room for debate about the methodology, but the findings ring true. That is, that managers who favour people like themselves discourage the productivity of a diverse workforce. Bias is simply malfunctioning thinking. Leading an organization with malfunctioning thought would presumably be a hindrance to workplace effectiveness.
