The diversity-validity dilemma in complex selection decisions

The diversity-validity dilemma in complex selection decisions

The diversity-validity dilemma arises when valid selection predictors cause adverse impact. In this paper we discuss the diversity-validity dilemma within the complex selection context, which encompasses an applicant pool and several open positions. Some applicants apply for one of the available positions, while others apply for more than one or even all positions. Complex selection decisions select some applicants and assign them to a specific position. We present two methods to estimate the expected selection quality and adverse impact ratio (AIR) of such decisions, in case they are based on a weighted combination of several predictor scores. Additionally, these two methods are implemented in a multi-objective optimization algorithm to develop complex selection decisions that result in a Pareto-optimal trade-off between selection quality and AIR. Pareto-optimal trade-offs are trade-offs between the two outcomes that cannot be bettered simultaneously by any other (complex selection) decision.
