Not a Chimp – Jeremy Taylor ****

Jeremy Taylor’s aim in this book is to show how a fashionable idea among scientists and science communicators – that the gap between human and chimpanzee cognition and behaviour is almost negligible – is in fact hugely mistaken.
The belief that there is little difference between humans and chimpanzees in terms of cognition and behaviour is significantly based on genetic studies of recent years which have appeared to show that the human and chimpanzee genomes are roughly 98.4% identical. But as Taylor points out in the earlier sections of the book, genetic similarities don’t necessarily entail cognitive and behavioural similarities, especially when only a small handful of genes can have the ability to make one species dramatically different from another. In any case, these earlier sections explain, there is good reason to believe that the 98.4% figure is misleading: when we study more closely the two species’ genomes, we notice, for example, that many of the genes we share with chimpanzees are active in chimps but are no longer active in humans; that identical genes are expressed differently in humans and chimps; and that some of the genes we share with chimps have been duplicated in human beings, increasing the effects of these genes in humans.
Added to this, we find out later in the book that there is no clear evidence that chimps possess a theory of mind like the human capability. This enables us to appreciate the hidden intentions, beliefs and desires of somebody else by merely observing their actions. We find, indeed, that crows are in many respects more cognitively advanced than chimps. All of these fascinating insights go to show how far we are set apart from chimps, and they mean that it is not difficult for us to account for unique traits in humans like artistic creativity and the ability to develop complex languages.
Throughout the book, Taylor presents the material in a way that is accessible to the general reader, and the amount of research he describes and brings together makes his arguments, by and large, very convincing, and means the book is likely to be appealing even to experienced primatologists.
There is one respect in which the book could have been a little stronger, and this is where the focus moves away from the science and on to the question of whether we should extend certain human rights to chimpanzees – the right to life and to protection from torture, for example – as some, like the philosopher Peter Singer, have suggested. Taylor criticises this view given the differences between the species mentioned above but, at times, gives the impression that people like Singer want us simply to view chimpanzees as fully human, which no one is suggesting. Ultimately, here, there is a slight tendency here not to appreciate the arguments and positions of the other side and to oversimplify the issues.
Only a small portion of the book is dedicated to that discussion, however, and Taylor’s clear and comprehensive coverage of the science more than makes up for any shortcomings elsewhere. There is much in the book we need to bear in mind when thinking about our relationship with chimpanzees and the rest of the animal kingdom, and I would recommend it.

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, ...
