Models of inequity

Sharpening the fuzzy process of bias, discrimination and inequity so we an address it



Assumed audience:

People with an interest in evidence-backed interventions to improve equity, in the west generally, especially technical workplaces

Scrapbook to collect various models of how inequity on various axes arises and is maintained. Having models for this is a good idea; otherwise we need to try to guess what we can change, what we cannot, and what the tradeoffs are, using only feelings. Yet our feelings need help.

Game-theoretical models

Cailin O’Connor’s The Origins of Unfairness: Social Categories and Cultural Evolution (O’Connor 2019).

Hilbe’s inequality model (Hauser et al. 2019) is another (?) game theoretic model of the difficulties of coordinating in an unequal society.

Possibly related: collective action.

Cumulative advantage

Du, Nordell, and Joseph (2021) is a model of how gendered the promotion pathway is for non-obvious reasons:

The term glass ceiling is applied to the well-established phenomenon in which women and people of color are consistently blocked from reaching the upper-most levels of the corporate hierarchy. Focusing on gender, we present an agent-based model that explores how empirically established mechanisms of interpersonal discrimination co-evolve with social norms at both the organizational (meso) and societal (macro) levels to produce this glass ceiling effect for women. Our model extends our understanding of how the glass ceiling arises, and why it can be resistant to change. We do so by synthesizing existing psychological and structural theories of discrimination into a mathematical model that quantifies explicitly how complex organizational systems can produce and maintain inequality. We discuss implications of our findings for both intervention and future empirical analyses, and provide open-source code for those wishing to adapt or extend our work.

Their model auditions various, apparently-individually-minor, points of adverse gender discrimination and finds that the overall result is large divergence between outcomes. This is a stylised model, it matches my understanding of the world well.

Conflict theory

Inequality between groups arises because groups can coordinate to capture more resources for themselves at the expense of another group. See conflict theory.
