Watson’s science had intersected with real life. The massive international project to map the human genome would no longer be for him an abstract, academic pursuit. It was personal, and it would ingrain in him a belief, bordering on obsession, in the power of genetics to explain human life. Nature, not nurture, made Rufus the way he was, and it also made different groups of people the way they were.
It's personal - which makes it more interesting of course.
