The heritability of moral standards for everyday dishonesty

Previous research on the acceptability of dishonest actions has focused on the role of social norms and internal reward mechanisms. Using a sample of over 2000 Swedish adult twins, this manuscript examines whether there exists another source that is driving differences in perceptions of the acceptability of dishonest actions: genetic variation. We find that much of the variation in perceptions of the acceptability of dishonest actions is attributable to genetic variation between individuals.
