Julian Baggini reviews it here. Most books on the subject don’t engage the social dimension of science – it looks like this one is an important exception. Excerpt:
While it is central to science that its theories are based on evidence and can be tested, there is a great deal of judgment required when deciding which experiments are critical or what evidence is decisive. There is no method you can simply follow that will determine these issues for you. Breakthroughs often occur because scientists are too bloody-minded to give up on their ideas in the face of unpromising results.
