The twins' father, Walker Inman, 57, lumbered from the mansion, his tattooed sleeves visible under a black T- shirt, drinking his morning rum ... He'd been full of dangerous mischief since he was a child. As a 13-year-old orphan in 1965 taken in by his aunt Doris Duke, Walker – then called "Skipper" – had romped around her lavish 14,000-square-foot Hawaiian estate without regard for property or propriety That single word "orphan" is the most important part of this article. The reason this piece is so bizarre is that the sorts of traits that allow you to build great fortunes in business[1] are anti-correlated with those that result in becoming a tattooed, drunk, abusive, morbidly obese, criminally-inclined drug addict. Put another way, the kind of guy who would build up a fortune like that would be unlikely to have a biological son like this. In America we're supposed to pretend that DNA doesn't matter, and that you can only pass down looks/height and not brains/behavior, but reality doesn't work like that [2,3,4]. Babies put up for adoption at birth in particular tend to disproportionately be children of parents with low impulse control and mental disorders, and at least some of that appears to be due to the genetics of the parents above and beyond the orphanage conditions [5]. Sounds harsh, but good to know if you're considering adopting. [1] Celebrities and athletes are of course excluded from this sentence. They don't become wealthy through scaling businesses/managing people, and as such have a much higher incidence of behavioral issues. Many NBA and NFL athletes are bankrupt after a few years out of the league, in fact.

The Minnesota psychologist and her colleagues found that disparity could be due as often to innate factors such as perinatal care or his birth parents' genes. "The deleterious effects may quite possibly have come before the adoption ever took place," Keyes, the study's lead researcher, says.
