This book has not been written for the policy analyst, but for those members of the science and technology community who either don't understand why science gets made a part of a political discussion or don't understand why their injection of scientific argument into a political discussion does little to resolve (and sometimes much to inflame) the argument. Pielke makes use of some very effective, if unsubtle, instruments to make his points and, as such, this text may irritate those who see much subtlety and complexity to the development of science and technology policy. However, as a primer for those who think "we just have to get the science right and then the problem will be resolved" (or, more importantly, for those who have found this to be a fallacy, but don't understand why), this is a powerful introduction. Moreover, while many elements of his argument can be found in his published work on climate change, it's nice to see it all brought together in one title.
The book's only real weakness is its effort to employ these notions to discuss elements of some of our present-day controversies. It's really stretching to use these notions to talk about the Bush Administration's rationales for the Iraq War, even though it's understandable why he might want to develop examples from outside the science/technology domain. However, the author's personal politics shine through enough to distract the reader from the argument, IMHO.
