The "orchid hypothesis" suggests that genetics that lead to mental illness can also lead to exceptional and high functioning people when their lives are nurtured, like an orchid that thrives in a greenhouse but withers outdoors.
Not surprising to many folks I'm sure but comforting that it's being studied. Long article but eventually gets to the point. It goes beyond the simple idea of "humans do better in a good environment", it suggests that "humans that are prone to come mental illnesses become exceptional in a good environment". Pretty significant validation for a group sorely in need of that.
I find this notion reinforces my intuitive approach to wellness, that I will live well not by suppressing the excruciating sensitivity I was born with, but by nurturing and embracing it.
