I had assumed that this book would basically be a fairly simple debunking exercise. With each chapter introducing a different kind of "woo-woo" (as sceptic legend James Randi terms it), then explaining why it's a load of rubbish.
What I got was infinitely deeper, more nuanced and more respectful of heresy, and it has completely changed the way I look at some of these people. Being of a logical, more scientific bent myself, I have often been condescending to such beliefs.
Now don't get me wrong. Will Storr isn't afraid to say that these people are nearly always wrong, and provably so. And some of these people (I'm thinking David Irving and Lord Monckton in particular) don't inspire sympathy in any way shape or form, but by trying to understand WHY they believe what they do, rather than just attacking those beliefs, (which, as the book demonstrates, is completely futile) really gave me a completely different perspective on the issues.
When Storr gets a little deeper and goes into the various ways our brains trick us, all of us, every day, it really pushes the book into 'must-read' territory.
This is really life-changing stuff, and terrifically entertaining to boot. Superb!
