Genes load the gun, environment pulls the trigger: nature and nurture reframed

Experts on obesity, autism, individuality and hormones all describe traits as genetic predispositions that the environment either triggers or restrains, and warn that heritability is widely misunderstood. It matters because it replaces fatalism with a clearer sense of what we can and cannot change.
