What's Your Bias? - Lee De-Wit ***

We have seen plenty of books on the psychology of decision making and how psychology can give us insights into the way that we misinterpret information or get things wrong, such as Richard Nisbett's Mindware, but this is the first that I have come across that explicitly addresses the psychology of the way we vote.

This is, perhaps, the ideal time to come out with such a book, as there have been so many surprise results in the last few years from the last two British general elections to Brexit and Trump. And there is some interesting material in this slim volume (I got through it on a longish train journey). It's very pleasing also, that Lee De-Wit gives us a good balance between UK and US examples.

Perhaps the most surprising result covered is the discover that the biggest predictor of how we will vote is how open we are to new experiences rather than, say, class or wealth. We also see how traditional party support has changed over time. Other aspects will be more familiar if you've read any popular psychology, such as the impact of confirmation bias. And there's also good coverage of the way social media and targeted internet advertising are changing the playing field.

Although this is an approachable, easy-to-read book, I went away from it a little disappointed, as it seemed just too lightweight - I felt like I was left wanting a lot more. More of the science, more insights and implications. It was a bit like reading a study (with lots of provisos) that gave you the basic facts, but didn't provide much in the way of discussion and conclusions. Even when dealing with social media, for example, we heard a lot about its existence and what was done with out, but little about its measurable impact on voters.

I would still very much recommend reading this book if you are at all interested in politics or what has been happening recently, particularly in light of the changes in social media. But I wish there had been a bit more to it.

Math Without Numbers - Milo Beckman *****

In some ways, this is the best book about pure mathematics for the general reader that I've ever seen.  At first sight, Milo Beckman's assertion that 'the only numbers in this book are the page numbers' seems like one of those testing limits some authors place on themselves, such as Roberto Trotter's interesting attempt to explain cosmology using only the 1,000 most common words in the English language, The Edge of the Sky . But in practice, Beckman's conceit is truly liberating. Dropping numbers enables him to present maths (I can't help but wince a bit at the 'math' in the title) in a far more comprehensible way. Counting and geometry may have been the historical origin of mathematics, but it has moved on. The book is divided into three primary sections - topology, analysis and algebra, plus a rather earnest dialogue on foundations of mathematics exploring the implications of Gödel's incompleteness theorems, and a closing section on modelling (

The Ten Equations that Rule the World - David Sumpter ****

David Sumpter makes it clear in this book that a couple of handfuls of equations have a huge influence on our everyday lives. I needed an equation too to give this book a star rating - I’ve never had one where there was such a divergence of feeling about it. I wanted to give it five stars for the exposition of the power and importance of these equations and just two stars for an aspect of the way that Sumpter did it. The fact that the outcome of applying my star balancing equation was four stars emphasises how good the content is. What we have here is ten key equations from applied mathematics. (Strictly, nine, as the tenth isn’t really an equation, it’s the programmer’s favourite ‘If… then…’ - though as a programmer I was always more an ‘If… then… else…’ fan.) Those equations range from the magnificent one behind Bayesian statistics and the predictive power of logistic regression to the method of determining confidence intervals and the kind of influencer matrix so beloved of social m

Reset - Ronald Deibert ***

The subtitle underscores a topic of 'reclaiming the internet for civil society'. There is no doubt that the internet has given us huge benefits - never more obvious than during the COVID pandemic - but Ronald Deibert argues that it also presents huge dangers, both from the state being able to gather data on citizens and from corporations indulging in 'surveillance capitalism' - making money out of keeping track of us and our data. Both of these are certainly significant issues that need to be explored. The majority of the book gives a depressingly dark picture of an internet where we are constantly observed, while the last pages come up with a form of response - the reset of the title. Unlike the stark specifics of the description of the problem, the suggested solution is far more tenuous, coming down primarily to being more 'republican' (with a small r, not the policies of the US political party of the same name). I'll be honest, I found Reset hard going,
