The idea
Twin and adoption studies find substantial heritability for major personality traits, with a large role for non-shared environment.
In practice
In the Minnesota twin study, several traits showed heritability above 0.50, including well-being and resistance to stress.
Where people slip
The environmental contribution is largely non-shared. Siblings in one home differ for environmental reasons.
