The Bias of Crowds: How Implicit Bias Bridges Personal and Systemic Prejudice

ABSTRACT

As public awareness of implicit bias has grown in recent years, studies have raised important new questions about the nature of implicit bias effects. First, implicit biases are widespread and robust on average, yet are unstable across a few weeks. Second, young children display implicit biases indistinguishable from those of adults, which suggests to many that implicit biases are learned early. Yet, if implicit biases are unstable over weeks, how can they be stable for decades? Third, meta-analyses suggest that individual differences in implicit bias are associated weakly, although significantly, with individual differences in behavioral outcomes. Yet, studies of aggregate levels of implicit bias (i.e., countries, states, counties) are strongly associated with aggregate levels of disparities and discrimination. These puzzles are difficult to reconcile with traditional views, which treat implicit bias as an early-learned attitude that drives discrimination among individuals who are high in bias. We propose an alternative view of implicit bias, rooted in concept accessibility. Concept accessibility can, in principle, vary both chronically and situationally. The empirical evidence, however, suggests that most of the systematic variance in implicit bias is situational. Akin to the “wisdom of crowds” effect, implicit bias may emerge as the aggregate effect of individual fluctuations in concept accessibility that are ephemeral and context-dependent. This bias of crowds theory treats implicit bias tests as measures of situations more than persons. We show how the theory can resolve the puzzles posed and generate new insights into how and why implicit bias propagates inequalities.
