It was very depressing to realize that, when looking around for regimes that have systematically corrupted science within the past century or so, three stood out quite distinctly, head and shoulders above the rest of the herd: Hitler’s Germany, Stalin’s Russia, and Bush’s America. At times when working on the three relevant chapters, I had to remind myself which chapter was the one in front of me: the parallels between the three regimes, in terms of their vigorous attempts to trample honest science underfoot, are as horrifically close as that.
