Distrust - Gary Smith ***

There is a lot in the news on misinformation and disinformation - Gary Smith explores the way three factors of this kind can tarnish the public's attitude to science. He suggests that there is rising distrust of science and scientists as a result of: disinformation (telling fibs), data torturing (where data is selectively used, for example choosing the time period that most emphasises the desired result) and data mining (where big data is misused by picking up on the inevitable random correlations that occur in large quantities of data without there being a causal reason for the correlation).

Smith makes the important point that in a world where we are presented with interpretations of so much data, a clear understanding of these three factors is essential if we are to make any sense of what we hear and read. While disinformation is often a problem when non-scientists present 'their truth' that is often used to attack science, data torturing and data mining is often undertaken by scientists themselves, reducing public trust in something that is essential for the functioning of modern society.

We then get a shorter section on AI, which makes the important point that most AI is not intelligent, nor is it flexible. Here he also takes on earlier versions of ChatGPT and the like and reasonably assesses their shortcomings, though he doesn't mention some of the areas where the technology is genuinely worrying, such as generating plausible student essays. But the nature of AI's intelligence or lack of it is better covered elsewhere, notably in Smith's excellent title The AI Delusion, and isn't the main thrust of this book.

Finally, Smith pulls it all together, looking at poor reproducibility, where scientists' results, for example, don't actually match the underlying data, highlighting the replication crisis, where attempts to replicate experiments fail, and delivering his solution for 'restoring the lustre of science'. The reproducibility and replication sections are excellent. The solutions are less so - but that's not really a criticism. It is just very difficult to come up with answers to these problems. There's a lot more chance with those involving scientific misdemeanours, such as the suggestion to reduce the importance given to statistical significance (as opposed to value of a result), and more importance given to quality, replicability and reproducibility - but almost inevitably the solutions on the disinformation side are much less likely to have much of an impact.

So far, so good - an important point is being made here, and though I've seen a lot in the media about the disinformation aspect, Smith does a service in making clear how easy it is to distort the interpretation of data using the other two means. Unfortunately, though there are some aspects of the book that didn't quite work for me. In part it's the way it's written, and in part a worry about the handling of a particular piece of data.

Smith has a light style despite the topic, but I sometimes found it too jaunty for a serious science book. For example, he refers to inhabitants of the UK as 'Brits'. If a UK-based writer referred to Americans as 'Yanks' in a science book I think it would rightly raise a few eyebrows. Sometimes, too, the structure doesn't quite work. For example, Smith gives us chapters on specific areas where the three factors come into play. In one of the disinformation chapters on 'Elite conspiracies', some of the subsections are on conspiracy theories driven by disinformation, but others, such as the Pentagon Papers, use of animal 'spies', and 24/7 surveillance, are about examples where the conspiracies were effectively real - however, there's no distinction made between the sections in the flow of the chapter. This doesn't work well - and this unusually unstructured approach continues through other chapters.

The factual error (entertainingly in a chapter on 'the post-fact world') was that Smith tells us 'The Sun, a UK tabloid newspaper that publishes all sorts of nonsense, has long included the disclaimer "SUN stories seek to entertain and are about the fantastic, the bizarre, and paranormal... The reader should suspend belief for the sake of enjoyment."' Unfortunately this disclaimer is taken not from The Sun, which is one of the largest circulation UK national newspapers, but from Sun, a now-defunct US supermarket tabloid. It might seem heavy-handed to point this out, but Smith claims a tool for spotting disinformation is when it looks doubtful. No one in the UK would fail to spot that this is wrong - the error demonstrates well how that ability to uncover disinformation is highly dependent on context and on your personal experience.

The concerns don't undo the fact that this is an important topic and Smith highlights issues in the areas of data torturing and data mining extremely well that haven't been exposed as much as they should be. It's a useful and timely book, but perhaps could have benefited from a more forceful editor.

  1. I don't see how you can discuss public distrust of science without mentioning those who deliberately generate such mistrust; for example the entire climate "scepticism" industry, "scientific" creationism, and, as we have seen in the case of Covid with deadly results, those who for political reasons undermine government mandates simply because they come from government.

    1. Those aspects are definitely included under the 'disinformation' part, but have been fairly widely covered elsewhere - I focused more on the other two parts because they are less written about. They are also used as ammunitions by those who do deliberately generate mistrust.

David Spiegelhalter Five Way interview

Professor Sir David Spiegelhalter FRS OBE is Emeritus Professor of Statistics in the Centre for Mathematical Sciences at the University of Cambridge. He was previously Chair of the Winton Centre for Risk and Evidence Communication and has presented the BBC4 documentaries Tails you Win: the Science of Chance, the award-winning Climate Change by Numbers. His bestselling book, The Art of Statistics , was published in March 2019. He was knighted in 2014 for services to medical statistics, was President of the Royal Statistical Society (2017-2018), and became a Non-Executive Director of the UK Statistics Authority in 2020. His latest book is The Art of Uncertainty . Why probability? because I have been fascinated by the idea of probability, and what it might be, for over 50 years. Why is the ‘P’ word missing from the title? That's a good question.  Partly so as not to make it sound like a technical book, but also because I did not want to give the impression that it was yet another book

The Genetic Book of the Dead: Richard Dawkins ****

When someone came up with the title for this book they were probably thinking deep cultural echoes - I suspect I'm not the only Robert Rankin fan in whom it raised a smile instead, thinking of The Suburban Book of the Dead . That aside, this is a glossy and engaging book showing how physical makeup (phenotype), behaviour and more tell us about the past, with the messenger being (inevitably, this being Richard Dawkins) the genes. Worthy of comment straight away are the illustrations - this is one of the best illustrated science books I've ever come across. Generally illustrations are either an afterthought, or the book is heavily illustrated and the text is really just an accompaniment to the pictures. Here the full colour images tie in directly to the text. They are not asides, but are 'read' with the text by placing them strategically so the picture is directly with the text that refers to it. Many are photographs, though some are effective paintings by Jana Lenzová. T

Everything is Predictable - Tom Chivers *****

There's a stereotype of computer users: Mac users are creative and cool, while PC users are businesslike and unimaginative. Less well-known is that the world of statistics has an equivalent division. Bayesians are the Mac users of the stats world, where frequentists are the PC people. This book sets out to show why Bayesians are not just cool, but also mostly right. Tom Chivers does an excellent job of giving us some historical background, then dives into two key aspects of the use of statistics. These are in science, where the standard approach is frequentist and Bayes only creeps into a few specific applications, such as the accuracy of medical tests, and in decision theory where Bayes is dominant. If this all sounds very dry and unexciting, it's quite the reverse. I admit, I love probability and statistics, and I am something of a closet Bayesian*), but Chivers' light and entertaining style means that what could have been the mathematical equivalent of debating angels on
