The context was about the lack of science popularization, and he took the example of this book and his author, which he copiously insulted, and said it was exactly the reason why scientists do not trust journalists and avoid them, because while being ignorantly misquoted and misunderstood isn't a good feeling, being approached with bad intentions and being misread and misquoted on purpose in order to push political agenda is worse. I would have to research more on why this book in particular was on his mind, but i would bet that most geneticists think this book is hogwash.
