The Practical Impact of Bias against Minority Group Applicants in Resume Screening on Personnel Selection Outcomes

Research has consistently shown that resume screening decisions, despite their practical importance and frequent use in practice, are prone to biases that disadvantage applicants in demographic minority groups. Using a two-stage multiple-hurdle selection simulation as an example (initial selection on resume scores, then selection on a composite of cognitive ability and conscientiousness test scores), the current study illustrates the practical impact that bias against ethnic minority group applicants in resume evaluation can have on the outcomes of selection. Results show that if the bias against minority group applicants creates even a modest level of deflation in the observed resume evaluation scores for minority group applicants, the selection rate for minority group applicants is expected to be meaningfully lower compared to the selection rate for majority group applicants, increasing the likelihood of adverse impact. These findings demonstrate in clear practical terms the critical importance of fair resume evaluations for improving the legal defensibility of selection. Going beyond the simple understanding that bias against minority group applicants in resume screening leads to lower diversity, the current study contributes to the previous literature by clearly outlining the expected effect that varying levels of discriminatory resume evaluation have on the practical outcomes of selection. Moreover, we illustrate these results under a realistic set of conditions implied from the personnel selection literature and meta-analyses of variables relevant to personnel selection
