 Alternatively, game theoretic analysis can also help us understand practices like open defecation which seem to be sustained not by pluralistic ignorance, but by a strong commitment to norms that outweigh the concern of individuals or communities for things like public health. For instance, in rural India where open defecation is common, the practice tends to be sustained by purity norms that interact with caste systems in ways that make communities reluctant to utilize latrines even when they are made available. Combating the public health crises exacerbated by open defection is thus not only a matter of building the requisite infrastructure, but of undermining the prevailing norms that prevent the infrastructure from being utilized (Coffey &amp; Spears 2017), and of incentivizing individuals to police new norms that promote better sanitation practices (Bicchieri 2017). And, in such cases, game theoretic analysis allows us to see how the relevant behaviors might be incentivized.
