Children pass the Sally-Anne false-belief task around age four. Theory of mind is a discrete cognitive achievement with measurable neural substrate. The Social Quotient finally treats it as the foundation it is.
Theory of mind — the capacity to model what someone else believes, even when their belief is false — is not a personality trait. It is a discrete cognitive achievement with a developmental window (age four for typical children, later for some) and a measurable neural substrate (the temporoparietal junction and medial prefrontal cortex). The Sally-Anne false-belief task is the founding instrument.
Cooper's Social Quotient volume tracks the working assessment instruments — SSIS, the CASEL framework, theory-of-mind probes, perspective-taking measures — and treats SQ as the substrate of the emergent Trustworthiness Quotient (TQ), which arises from the joint distribution of EQ, SQ, and RQ. Raj Chetty's 2022 Nature finding that cross-class friendships are the strongest predictor of upward mobility anchors the social-capital chapter. Robert Putnam's Bowling Alone and Sebastian Junger's Tribe bracket the cultural reading.
