Experience, in the context of heritability, should be understood broadly to include prenatal factors, gut bacteria, and all environmental influences from fetal development to death.

“the problem I have with nurture is that it is too narrow a term that really it should be replaced with the word experience and experience in the broadest possible sense not just social experience but uh the foods your mother ate when she was carrying you in utero um the diseases you fought off or your mother fought off while she was carrying you um in utero the bacterial population of your gut uh so experience meaning anything that impinges on you starting from the earliest stages of fetal developments uh continuing to the last day of your life I think it should be very expansive much much more than social experience in the family or the or the community”
