It’s page 179 of my colleague Virgil Storr and Ginny Cho’s best book of 2019. Do markets corrupt our morals?:
While everyone seems to trust those with short social distance (ie, family and neighbor trust) equally in both market and non-market societies, trust appears to decline as social distance increases and declines rapidly in non-market societies…. Stated alternatively, people around the world seem to have equally strong core networks, but those living in market societies seem to have stronger lateral networks.
