From Bias to Behavior: Understanding the Theoretical Gaps in Diversity Training

As workforce demographics shift to become more diverse, diversity, equity, and inclusion (DEI) programs have evolved to address legal issues related to climate and inclusion. Common to most DEI efforts is bias reduction training, but this approach has faced substantial criticism. Multiple reviews indicate that diversity training is minimally effective and may even provoke backlash or decrease diversity. However, there has been limited exploration of why these approaches fail. This chapter investigates the central concepts, assumptions, and theoretical mechanisms behind bias reduction strategies and proposes a theoretical and methodological approach to addressing inequality at micro- and macro-levels.

The authors conduct a cross-disciplinary review of the diversity training literature, with a specific focus on the psychological research examining the attitude–behavior relationship, models of behavior change, bias reduction interventions, and intergroup contact theories.

The authors’ review highlights that diversity training predominantly focuses on individual-level cognitive efforts to raise awareness of bias and modify behavior by changing implicit and explicit attitudes. Most studies rely on self-reported attitudes, behavioral intentions, and the Implicit Association Test (IAT) as a measure of implicit bias, often lacking long-term assessment.

Despite weak evidence, organizations continue to use bias reduction training. The authors provide recommendations grounded in theory, incorporating context and interaction.

The authors identify the theoretical shortcomings of current diversity training and present a structural social psychological approach that leads to strategies for modifying and measuring behavioral inequalities.

While many reviews report limited efficacy, this chapter offers a theoretical analysis of current diversity training approaches to explain their ineffectiveness.
