Why People Believe Weird Things – Michael Shermer ****

Michael Shermer is probably best known as Scientific American’s resident sceptic – a man who has what seems the wickedly enjoyable job of going around finding fault with other people’s beliefs – a sort of modern day court jester without (presumably – I’ve never seen him) the funny costume and bells. In this classic, originally published in 1997 but reviewed in a new UK edition, he gives a powerful argument for taking the sceptical viewpoint.
Although along the same lines as Carl Sagan’s The Demon Haunted World, this book works alongside Sagan’s masterpiece, rather than competing with it. It focuses more on why we believe strange things, and also very usefully expands out from the paranormal and pseudoscience to include pseudohistory, a topic I hadn’t even realized existed.
Shermer is something of a convert to scepticism, so has a convert’s fervour, but none of the unpleasant aggressiveness of the likes of Randi and Dawkins. Instead he gently shows us how strange beliefs come into being, and why they have such a strong hold. Inevitably strong on the paranormal and UFOs, he is particularly good when looking at the likes of modern accusations of satanic rituals, and the remarkable cult of Ayn Rand. The section on creationism is a little weaker, partly because it isn’t quite up-to-date enough, and also because there has been so much material going into this in more depth (see, for example, Scientists Confront…)
In some ways I was most impressed by the next section on pseudohistory, in part, I suspect, because of not having really thought about this as a concept before. The chapters on holocaust denial were fascinating, and perhaps even more surprising was the self-deception of the ‘all ideas originated in Africa’ movement (again new to me).
The only reason that this book doesn’t get 5 stars is that I found the last section before getting to the summaries, on a scientific idea that its originator says gives a mechanism for a form of eternal life, irritating. It just isn’t the same sort of problem as the other topics covered in the book. Here someone is speculating wildly based on extrapolating scientific theories to the extreme – but that’s a very different game to having an unshakable belief in concepts with no support in evidence, and I think Shermer does himself and the reader a disservice by confusing the two. However, the book doesn’t entirely end on this mistake, as there are a couple of short chapters pulling together the whys and wherefores of belief in weird things, so this small glitch doesn’t destroy the flow, and certainly shouldn’t detract from the fact that overall this is a book, alongside Sagan’s, that ought to be on every thinking person’s shelf.

It's On You - Nick Chater and George Loewenstein *****

Going on the cover you might think this was a political polemic - and admittedly there's an element of that - but the reason it's so good is quite different. It shows how behavioural economics and social psychology have led us astray by putting the focus way too much on individuals. A particular target is the concept of nudges which (as described in Brainjacking ) have been hugely over-rated. But overall the key problem ties to another psychological concept: framing. Huge kudos to both Nick Chater and George Loewenstein - a behavioural scientist and an economics and psychology professor - for having the guts to take on the flaws in their own earlier work and that of colleagues, because they make clear just how limited and potentially dangerous is the belief that individuals changing their behaviour can solve large-scale problems. The main thesis of the book is that there are two ways to approach the major problems we face - an 'i-frame' where we focus on the individual ...

Introducing Artificial Intelligence – Henry Brighton & Howard Selina ****

It is almost impossible to rate these relentlessly hip books – they are pure marmite*. The huge  Introducing  … series (a vast range of books covering everything from Quantum Theory to Islam), previously known as …  for Beginners , puts across the message in a style that owes as much to Terry Gilliam and pop art as it does to popular science. Pretty well every page features large graphics with speech bubbles that are supposed to emphasise the point. Funnily,  Introducing Artificial Intelligence  is both a good and bad example of the series. Let’s get the bad bits out of the way first. The illustrators of these books are very variable, and I didn’t particularly like the pictures here. They did add something – the illustrations in these books always have a lot of information content, rather than being window dressing – but they seemed more detached from the text and rather lacking in the oomph the best versions have. The other real problem is that...

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader.  We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard.  This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...
