Monocultural Biases: Correlated biases in large language models lead to unequal systemic exclusion rates in hiring

Summary
A study has found that large language models used in hiring introduce monocultural biases, leading to higher systemic exclusion of certain demographic groups.
Post-training of these models increases agreement in hiring decisions but decreases callback rates for older applicants, raising exclusion rates from 5.6% to 17.3%.
Researchers warn that widespread LLM adoption may amplify age-based discrimination and systemic inequality, urging regulators to standardize bias audits across the labour market.
