A Debate about Algorithmic Monocultures in Hiring: Vendor Bias and Systemic Exclusion

This research explores the phenomenon of algorithmic monoculture in the labor market, where a high concentration of employers relies on the same few vendors for automated hiring tools. Research into millions of applications suggests that while vendors may claim overall fairness, disaggregated data reveals significant racial bias at the individual position level. This widespread dependency creates a systemic exclusion effect, where an applicant rejected by one algorithm is likely to be automatically disqualified across many different firms. The research argues that this lack of vendor diversity and transparency undermines legal protections and economic productivity by trapping qualified candidates in a cycle of unemployment. To address these vulnerabilities, the research advocates for regular bias audits, increased regulatory oversight, and the implementation of human-centered oversight in the recruitment process. Ultimately, the research warns that unchecked algorithmic consolidation transforms localized hiring errors into structural barriers for marginalized job seekers.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
