We argue that the core social being system is unlike other core systems in that it participates in frequent, widespread learning. As a result, the social being system is less constant throughout the lifespan and less informationally encapsulated than other core systems. This learning supports the development of the precursors of bias, but also provides avenues for preempting it.

Tomasello et al. argue that cultural cognition derives from humans' unique motivation to share psychological states. We suggest that what underlies this motivation is children's propensity to seek out the underlying causes of behavior. This propensity, combined with children's competence at it, makes them especially skillful at acquiring the intentional, conventional, and reliable forms that constitute culture.
