Proof: Adam Kucharski ***

This seemed to be a book that had a lot going for it. The topic of 'the science of certainty' appealed to a reader like me who is fascinated by probability and statistics, and I enjoyed the way the introduction made use of the uncertainty of the impact of the Eyjafjallakökull volcano on flight safety, then the delight that is the Monty Hall problem. But although the rest of the book had some highlights, I couldn't get on with much of it.

In a way, the title is highly misleading, because the book isn't really about 'proof' - after all, very little science involves proof. Certainly most of the studies we see misreported in the press don't. We can only prove something with perfect knowledge. This is fine when applying basic logic. We can make deductions, for example, if we are able to make a statement like 'no square is circular'. But such statements are rarely applicable in the real world. Instead we have to rely on induction or abduction, which is usually the case in science - meaning the best we can do is to have currently supported theory given the evidence available that may change in the future. Proofs work for abstract mathematics (also authors to read and for puddings), but not often in the real world.

This was fine (although I would have enjoyed a book on logic too), and it was interesting to cover ground on p values and frequentist statistics (though I would have liked more than the relatively quick dip into Bayes we get). But the problem was that the vast majority of the book didn't really cover this at all, focussing at length on dealing with the COVID pandemic, and to a lesser extent on taking a logical approach to proof in legal argument.

Both these specifics - Adam Kurcharski's personal experience during COVID and Abraham Lincoln's legal work - would have made excellent cases studies for a couple of pages, but they went on and on interminably. There are plenty of books about dealing with the pandemic - if I wanted to read one of these, I would have done so - but this isn't labelled as a such. I would have liked a whole range of scientific proof issues, taking in physics and cosmology and the other sciences as well. I admit I generally avoid reading about medical science, so this was a bit of a personal issue as well - but this wasn't supposed to be a book about medical science.

It didn't help that the book lacks structure, jumping around from topic to topic in a random-feeling fashion. Bottom line: if you want to find out more about the probability-based decisions made by COVID scientists (from an inside source, as Adam Kucharski was one of them), this is one for you. But if you want an engaging, wide ranging book on the nature of proof (or, rather, the lack of it) in science, this doesn't do what it says on the tin.

The Antigravity Enigma - Andrew May ****

Antigravity - the ability to overcome the pull of gravity - has been a fantasy for thousands of years and subject to more scientific (if impractical) fictional representation since H. G. Wells came up with cavorite in The First Men in the Moon . But is it plausible scientifically?  Andrew May does a good job of pulling together three ways of looking at our love affair with antigravity (and the related concept of cancelling inertia) - in science fiction, in physics and in pseudoscience and crankery. As May points out, science fiction is an important starting point as the concept was deployed there well before we had a good enough understanding of gravity to make any sensible scientific stabs at the idea (even though, for instance, Michael Faraday did unsuccessfully experiment with a possible interaction between gravity and electromagnetism). We then get onto the science itself, noting the potential impact on any ideas of antigravity that come from the move from a Newtonian view of a...

The World as We Know It - Peter Dear ***

History professor Peter Dear gives us a detailed and reasoned coverage of the development of science as a concept from its origins as natural philosophy, covering the years from the eighteenth to the twentieth century. inclusive If that sounds a little dry, frankly, it is. But if you don't mind a very academic approach, it is certainly interesting. Obviously a major theme running through is the move from largely gentleman natural philosophers (with both implications of that word 'gentleman') to professional academic scientists. What started with clubs for relatively well off men with an interest, when universities did not stray far beyond what was included in mathematics (astronomy, for instance), would become a very different beast. The main scientific subjects that Dear covers are physics and biology - we get, for instance, a lot on the gradual move away from a purely mechanical views of physics - the reason Newton's 'action at a distance' gravity caused such ...

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 ...
