It was a dazzling idea—the ideal experiment—the kind researchers dream about, but would not dare to conduct because disrupting human lives is a dangerous endeavor with unforeseen consequences. In 1993, about fifteen years since the project ended, Dr. Peter Neubauer agreed to be interviewed by New Yorker magazine staff writer Lawrence Wright who was researching an article on nature-nurture questions.39 Neubauer boasted that the prospective design of his study was “unique,” elevating it above the other reared-apart twin projects that had relied on the recollections of adults. When I met Neubauer at his home in 2004 he expressed similar satisfaction that his team “was there at the birth.” And he was open about his attempts to persuade another adoption agency to place twins apart.40 His study ended when the twins turned twelve, but if controversies over his work had not been played out so publicly it may have lasted longer.”
