										<content:encoded><![CDATA[
<p class="wp-block-paragraph">There is a gap between the calm, rational decision-makers we often aspire to be and the overwrought, sentiment-tossed creatures we often are. Rarely is that gap wider than in the political arena. Policy seems like it should be a matter for cool, evidence-based deliberation, but politics is soaked in emotion. </p>



<p class="wp-block-paragraph">This is not wholly to our collective advantage. Emotions often lead us astray. The behavioural economist George Loewenstein, in a 1996 paper titled “Out of Control: Visceral Influences on Behavior”, noted that extreme visceral emotions often lead to self-destruction. There is the alcoholic who is willing to abandon her children for the sake of the next drink; the suspect in a long interrogation who will sacrifice years of freedom for a glass of water and the chance to sleep; the arachnophobe who will risk injury in a scramble to escape from a toy spider that he knows perfectly well cannot hurt him; the road-raging driver who knows, somehow, that he is doing himself no favours even as he swings the punch. In the grip of emotion, we are not our best selves. </p>



<p class="wp-block-paragraph">We are also often unreflective about this fact. “People underweigh, or even ignore, visceral factors that they will experience in the future, have experienced in the past, or that are experienced by other people,” writes Loewenstein. </p>



<p class="wp-block-paragraph">Hard experience suggests this is true, but we also have some light-hearted experimental evidence on the visceral emotion of gluttony. Daniel Read and Barbara van Leeuwen ran a study in which participants chose between snacks ranging from apples to Mars bars. If the snack was for immediate consumption, people chose the chocolate bar. If told they were pre-ordering for next week’s follow-up, they chose fruit. A week later, offered a chance to change their minds, they caved and grabbed the Mars bar again. </p>



<p class="wp-block-paragraph">The point — familiar but deep — is that we are consistently inconsistent, intending good things for the future, surrendering to our animal selves when the future arrives, and then somehow expecting to do better next time. What is true for snacks may also be true for how we choose to engage in politics. In principle, favouring the apple of thoughtful discussion, while in practice seizing the Mars bar of furiously retweeting angry influencers. </p>



<p class="wp-block-paragraph">Intuitively, it seems that politics is more emotionally fraught than it was a generation ago. Is that right — and if so, why? A recent working paper from Eva Davoine, Stefanie Stantcheva, Thomas Renault and Yann Algan trawled through posts on X. They used a large language model to evaluate the emotional content of tweets from US citizens on political subjects including abortion, immigration, tax and inequality, and democracy itself. (Stantcheva and her colleagues went to some lengths to check that the people behind the accounts really exist.) </p>



<p class="wp-block-paragraph">Two findings immediately emerged. The first is that of all the emotions expressed in tweets, by far the most common is anger. Other emotions, positive and negative (fear, disgust, gratitude, hope, joy) barely appear, but anger is everywhere. </p>



<p class="wp-block-paragraph">The second is that anger is on the rise. The data starts in 2013, when Barack Obama was president, and for years about 25 per cent of political tweets were angry, and about two-thirds expressed no clear emotion. Anger started rising in 2016 and by 2020, between 40 and 50 per cent of political tweets were angry. That is partly because some calm tweeters have quit and been replaced by some angry ones, but mostly it is the same people as ever, tweeting more angrily than they once did. </p>



<p class="wp-block-paragraph">Who are the angriest tweeters? People at the political extremes, both left and right; people who follow a lot of politicians and political influencers; and, interestingly, people over the age of 65. The boomers are furious, at least the ones doing politics on social media. (Women express more anger than men, and Republicans more than Democrats, but, in both cases, the margins are small.) </p>



<p class="wp-block-paragraph">The researchers also look at the “supply” of anger from politicians and find, again, large increases since 2013. They also find strong political cycles (politicians in opposition are much more likely to express anger) and that while there was a sharp rise in angry tweets from politicians, there was a far more muted rise in angry speech on the floor of Congress. </p>



<p class="wp-block-paragraph">That contrast between social media and traditional speechmaking is instructive. It’s quite possible that people are angry in response to real problems, and it’s also possible that people are angry because the defining political figure of the age, Donald Trump, both uses and generates anger. </p>



<p class="wp-block-paragraph">But it may also be that anger is on the rise because the medium of political discussion encourages it. Stantcheva and her colleagues find that angry tweets by citizens are nearly 90 per cent more likely to be retweeted than non-emotional tweets, while angry tweets from congressional politicians are nearly 50 per cent more likely to be retweeted. If social media rewards anger, people will respond to the incentive. </p>



<p class="wp-block-paragraph">This may also explain the rise of populism. A recent study by George Ward, Sandra Matz and others found a correlation between negative emotions — fear, anger, depression, sadness — and support for populists and populist causes including Brexit in 2016 and Donald Trump in 2016 and 2020. The causal chain is too stretched to claim confidently that social media caused Brexit and Trump, but it is perfectly plausible to suggest that Twitter was fertile soil for populist seeds to sprout. </p>



<p class="wp-block-paragraph">There is nothing new about anger in politics. “Before the Hate had proceeded for thirty seconds,” wrote George Orwell in Nineteen Eighty-Four (1949), “uncontrollable exclamations of rage were breaking out from half the people in the room. The self-satisfied sheep-like face on the screen, and the terrifying power of the Eurasian army behind it, were too much to be borne.” </p>



<p class="wp-block-paragraph">Orwell wasn’t just trying to imagine the future, but refracting the vicious propaganda of the 1930s and 1940s. He knew very well that we are not our best, most reflective selves when we are angry — ruthless politicians will exploit that. </p>



<p class="wp-block-paragraph">George Loewenstein argued not just that we are often powerless in the face of strong emotions, but that we are in denial: we tend to tell ourselves that visceral feelings will not get the better of us, when all too often they do. </p>



<p class="wp-block-paragraph">Better to avoid temptation. A well-stocked bar is no place for a recovering alcoholic. It’s always easier to diet if the Mars bar is in a far away supermarket rather than the kitchen shelf. And if you’re interested in politics, John Stuart Mill’s On Liberty is always worth a read, but at all costs stay away from Bluesky and X.</p>

<p class="wp-block-paragraph">In these pages, and in my <a href="https://amzn.to/4tlZMVj">last book</a>, I’ve written about the lessons we should learn from Richard Doll and Austin Bradford Hill’s investigations in the 1950s into the link between cigarettes and lung cancer. There is one lesson I failed to draw. I wrote that in 1954 the British epidemiologists Doll and Hill “marshalled some of the first compelling evidence that smoking cigarettes dramatically increases the risk of lung cancer”. That is not untrue, but neither is it the whole truth. </p>



<p class="wp-block-paragraph">Two pathologists, Eberhard Schairer and Erich Schöniger, published a study of “lung cancer and tobacco consumption” well before Doll and Hill took up the question. Schairer and Schöniger began by noting that lung cancer, a rare disease in the 19th century, had shown a “pronounced increase”, and then dismissed the plausible-seeming idea that the cause was vehicle exhausts. Lung cancer was on the rise in rural areas just as much as urban, they noted, adding that “the male gender is much more frequently afflicted . . . than the female,” yet “both genders are exposed to almost the same degree” to exhaust fumes. More plausible, they suggested, was that cigarettes were to blame. </p>



<p class="wp-block-paragraph">Schairer and Schöniger sent out questionnaires to the families of people who had died from cancer, and also to living men in their fifties (at peak risk of lung cancer), enquiring about their smoking habits. They found a strong correlation between being a heavy smoker and developing lung cancer, but no such link between smoking and stomach cancer. Schairer and Schöniger never pretended to have the last word on the subject, they thought their findings were not certain but “only likely”. It was a small study and there are question marks over the survey methods used. But decades later, Richard Doll himself described the study as “percipient” and “important” even if it fell short of decisive proof. </p>



<p class="wp-block-paragraph">Why, then, is the study not better known? The overwhelming weakness in Schairer and Schöniger’s study is simple: they were German, writing in German, and they published in a German scientific journal in 1943. The immediate consequence is that Doll and Hill didn’t see it. Copies of the study didn’t reach the UK at all during the war. </p>



<p class="wp-block-paragraph">But the problem for Schairer and Schöniger was not a language barrier or a failure of scientific communication because of the strictures of war. It was that their entire enterprise was fatally tainted by association with the Third Reich. Doll notes that in postwar West Germany, the study was ignored and that “interest in the effects of smoking waned, as a reaction to the anti-smoking policies of the Nazi government”. </p>



<p class="wp-block-paragraph">Those policies are striking indeed. Hitler was a vegetarian — a fact so well known as to have become a punchline — but he was also a non-smoker. Nazi anti-tobacco activists were fond of pointing out that Mussolini and Franco also abstained, while Churchill, Roosevelt and Stalin all smoked heavily. Nazi cartoons depicted grotesque caricatures of Jews and dark-skinned people drinking and smoking, connecting two Nazi obsessions: their fear of racial impurity and their fear of impure substances such as alcohol, tobacco and processed food. Some of the Nazi ideas about health, clean living and being ever vigilant about toxins feel unnervingly fashionable. </p>



<p class="wp-block-paragraph">The Third Reich pursued its promotion of healthy lifestyles with some good old-fashioned public health messaging with an overtone of “do it for the good of the nation” that is probably much more sinister with the benefit of hindsight. Inspiring posters pointed out that healthy Aryan women drank apple juice and did not smoke so they could produce healthy babies, while hard-working men could save so much money from quitting smoking that they could buy a Volkswagen. </p>



<p class="wp-block-paragraph">For chief propagandist Goebbels, there was a risk of taking this campaign against smoking too far. Many teachers smoked, and doctors, and for that matter many senior Nazis, including Hermann Göring. The propaganda ministry feared that a hardline wartime campaign against smoking would inevitably fail and the government would look foolish. </p>



<p class="wp-block-paragraph">Yet Hitler clearly felt quite passionate about the issue. In 1941, Karl Astel, a professor of medicine as well as a prominent racial hygienist, established the Scientific Institute for Research into the Hazards of Tobacco at Friedrich-Schiller University in Jena. Hitler sent a telegram of congratulations and 100,000 Reichsmarks from his personal office, a substantial sum. </p>



<p class="wp-block-paragraph">Astel was a strong supporter of Hitler as early as 1923, and received the “Golden Badge of Honour” for being one of the early members of the Nazi party. He was intimately involved in organising the Holocaust and even more closely associated with the murder of 200,000 disabled people. Shortly before the end of the war, and presumably contemplating being tried for war crimes, he killed himself. </p>



<p class="wp-block-paragraph">Astel also funded Schairer and Schöniger’s research. </p>



<p class="wp-block-paragraph">So how complicit were Schairer and Schöniger themselves in the evils of the Third Reich? We know little about Schöniger, but we do know that Schairer joined several Nazi organisations, including — along with 10 million others — the Nazi party. In an obituary essay, Schairer’s son declared that his father “never was a member of the resistance and he was not a hero” but that he was a “liberal person” who regarded the Nazi manifesto as “inhuman”. </p>



<p class="wp-block-paragraph">While it is only natural to want to know what Schairer and Schöniger thought and did about Hitler, that has very little to do with what they thought and did about the link between cigarettes and lung cancer. Their research was important and should have been influential, but it was ignored. At a distance of more than eight decades it’s easy to shrug; we figured out the link between cigarettes and cancer a few years later, after all. </p>



<p class="wp-block-paragraph">But the delay was real and deadly, especially in West Germany itself.

Public health campaigners and epidemiologists have always had powerful enemies in the form of Big Tobacco. But who needs an enemy if your loudest cheerleader is Adolf Hitler? </p>



<p class="wp-block-paragraph">For all our lofty aspirations to scientific rigour, we are social creatures, heavily influenced by the beliefs of those we admire and those we despise. But even those we despise are not deluded about everything. The Nazis were so monstrously wrong about so many things that it is hard to imagine that they were ever right. Life is rarely that simple.</p>

										<content:encoded><![CDATA[
<p class="wp-block-paragraph">It was one of the most astonishing displays of persuasion I have ever seen. In the audience, a group of Midwestern agribusiness types, who by profession should have been well attuned to climate change, but by culture were deeply sceptical. On the stage, a Germanic gentleman from one of the great Alpine reinsurance companies, presenting a meticulous analysis of how changes in rainfall and temperature were reshaping crop insurance premiums. The first, slightly awestruck question: “So . . . you think this climate change thing is real?” </p>



<p class="wp-block-paragraph">It was a testament to the persuasive power of an apolitical nerd. The audience realised that this insurance analyst had no interest in the Woke Dems — he was just describing the world as he saw it. But it was also a window into the way that our views about the world shape financial markets for risk, and financial markets for risk shape our views about the world. </p>



<p class="wp-block-paragraph">There are two venerable insurance industries, the French economist Michel Albert once explained. One has its roots in Alpine pastures, where Swiss villagers agreed to help each other out if one farmer’s cow died. The other was born in Edward Lloyd’s coffee house in 17th-century London, where sailors and shipowners would gather to gamble on which ships would sink and which would return safely to port. </p>



<p class="wp-block-paragraph">Today we call both of these activities “insurance”, but they have very different souls. The Swiss version is all about mutual assistance, figuring out who is part of a community and who is not, and sharing burdens. The London version begins with the insight that some risks are fun, but also that people like to be smart about those risks. </p>



<p class="wp-block-paragraph">Edward Lloyd himself created a network of well-informed correspondents across the ports of Europe and published a newsletter specialising in maritime cargo and foreign affairs. Cuthbert Heath, a Lloyd’s underwriter from the late 19th century onwards, went on to specialise in acquiring the data needed to sell insurance against losses from earthquakes and hurricanes. Selling well-priced insurance is a lucrative business, and the better the information and judgment about future risks, the better the business will be. </p>



<p class="wp-block-paragraph">Financial risk contracts have long provided incentives to improve the state of our knowledge. In the 16th century the inveterate gambler Girolamo Cardano revolutionised our understanding of probability, while in the 17th the comet guy Edmond Halley used data on births and deaths gathered in Breslau to demonstrate that the government was selling life annuities too cheaply. A decade ago, I saw an agricultural insurance expert tell agribusiness traders something they didn’t know about climate change. It is all part of the same process. </p>



<p class="wp-block-paragraph">With this noble tradition in mind, perhaps we should not be surprised that prediction markets are taking off. They are not new; in 2003 the <a href="https://timharford.com/2003/09/all-bets-are-off-at-the-pentagon-ft-features/">Pentagon had been pondering</a> a “Policy Analysis Market” in which people would trade on the risk of — say — a deadly terrorist strike, or, um, attacks on shipping in the Strait of Hormuz. The idea that the US intelligence community might host such a market was a political non-starter and the plan was dropped. </p>



<p class="wp-block-paragraph">Yet the controversial idea made some sense. Prediction markets collect information by offering money for it. Markets may not be perfectly efficient but they are often informative: if you want to understand whether Arsenal’s lead in the Premier League table is commanding or precarious, the betting odds are a good place to start. Prediction markets, like any betting market, aggregate information. </p>



<p class="wp-block-paragraph">The mood music, and the rules on gambling, have changed since 2003. Prediction markets such as Kalshi and Polymarket have become well known for offering contracts on all sorts of events, ranging from “Will Jerome Powell be arrested in 2025?” to degenerate nonsense such as “Will Jerome Powell say ‘Good afternoon’ during his December 2025 press conference?” </p>



<p class="wp-block-paragraph">The libertarian in me says that people should be allowed to bet on pretty much anything, but the economist in me has some concerns. Of course, there is a worry — or there should be — that some people find gambling ruinously addictive, especially with smartphones putting a slot machine in every pocket. </p>



<p class="wp-block-paragraph">But we should also be concerned that in trying to predict the future, we change it for the worse. It might indeed be useful to get a sense of whether Jerome Powell will be arrested, because it matters if he is. It does not matter whether he says “Good afternoon”, so there is little benefit in such a market existing. The market in “Good afternoon” does, however, create the clear risk that somebody tries to bribe or threaten Powell. </p>



<p class="wp-block-paragraph">That is probably the least of his worries, but it is not hard to find examples of betting markets corrupting the real world. The most obvious cases are of crooked sports bets, where athletes rig games for their own benefit — or the benefit of people who are bribing or threatening them. It’s not even necessary to throw a match: it’s possible to bet on all sorts of trivia that are only peripherally related to the result. </p>



<p class="wp-block-paragraph">Or consider Emanuel Fabian, The Times of Israel journalist who was offered bribes, then death threats, to change his report that an Iranian missile had struck near Jerusalem on March 30. A great deal of money was — courtesy of Polymarket — riding on the question of whether Iran had or had not succeeded in striking Israel. Without his consent, Fabian found himself forced into the perilous role of refereeing which side had won the bet. </p>



<p class="wp-block-paragraph">Fabian’s plight is one of those things that, with hindsight, was obviously bound to happen. Whether prediction markets mean that athletes are being threatened if they don’t change a game, or journalists are being threatened if they don’t change a news report, this all seems like something that could be better thought through. </p>



<p class="wp-block-paragraph">It would not be the first time that a new, disruptive industry smacked headlong into a problem that the stodgy old incumbents have understood for a very long time. In the early 1960s, life insurers were alarmed to discover that they were paying vast sums in compensation for “loss of limb” to policyholders in the Florida panhandle. One fellow lost a foot; fortunately he had a tourniquet with him . . . and insurance from several dozen different companies. Another chap bought insurance then shot off his own foot just 12 hours later “while aiming at a squirrel”. </p>



<p class="wp-block-paragraph">There’s an old-fashioned phrase for this: moral hazard. And perhaps some old-fashioned caution is in order. Betting on the future can protect us from risk, and it can make us smarter about risk too. But it can also corrode and corrupt. Let’s be careful.</p>

<p class="wp-block-paragraph">In Tudor England, the line between mathematics and the mystic arts is vanishingly thin. Straddling both worlds is John Dee, a brilliant scholar and astrologer whose intellect grants him access to the highest circles of power. Dee navigates the politics of the court by making bold prophecies, which win him royal favour.&nbsp;But even correct predictions may come with a price &#8211; and laying claim to the future is a dangerous game.&nbsp;</p>

<p class="wp-block-paragraph">Almost 51 years ago — when I was still a toddler — a gaming and science-fiction enthusiast named Lee Gold put together the first edition of an unusual collaborative role-playing-games magazine, Alarums and Excursions. This time last year, after 593 monthly editions, she abruptly stopped. Gold is in her mid-eighties, and her eyesight is no longer up to the task.</p>



<p class="wp-block-paragraph">Alarums and Excursions, or A&amp;E, was a quixotic project even by the standards of 1975. It was an Amateur Press Association, which meant that contributors would produce their own fanzines — a few pages of articles, ideas, fiction, art and comments on the zines of others — and then Gold would assemble them into a 100-page-plus compilation encompassing a vast variety of typefaces, layouts, writing styles and even paper colour. (Gold took on the project in part because the Los Angeles Science Fiction Society’s weekly zine was being overrun by articles about a brand new game, Dungeons &amp; Dragons.) The maximum size of each issue was defined by the size of Gold’s stapler, and she mailed out the zine-of-zines compilation to all contributors and to anyone else willing to pay for a copy. </p>



<p class="wp-block-paragraph">Back in 1975, that was a practical way to publish niche ideas, and the back-and-forth between different contributors made A&amp;E a kind of proto social-media community, vastly slower and more thoughtful than the 21st-century version. Zines were technologically superseded by electronic bulletin boards, blogs, YouTube and social media (G+, Google’s shortlived answer to Facebook, was a huge source of game-design chat for a while). But Gold kept going anyway, and so did her contributors. A&amp;E had some thin years, but in the issues before its demise it had been as voluminous as ever. We are all yearning for a bit more analogue in our lives, so zines are back. </p>



<p class="wp-block-paragraph">Some of the hobby’s leading designers (Robin Laws, Mark Rein-Hagen, Jonathan Tweet) cut their teeth as readers of or fanzine writers for A&amp;E. The leading professional role-playing magazines, Dragon and White Dwarf, were both outlived by A&amp;E. Dragon stopped print in 2007 after 359 monthly issues; White Dwarf is at 522 and counting, but we role-playing purists would suggest that it stopped covering the hobby decades ago to focus on miniatures and war-games. </p>



<p class="wp-block-paragraph">Gold’s achievement is all the more impressive given the boneheaded sexism she faced. In 1976, Gary Gygax — co-creator of Dungeons &amp; Dragons, and the most powerful man in the hobby — phoned Gold under the misapprehension that she was male. </p>



<p class="wp-block-paragraph">“You’re a woman!” Gygax said when Gold picked up the phone and identified herself. </p>



<p class="wp-block-paragraph">“That’s right,” she replied, adding how grateful she was that Gygax had created D&amp;D. </p>



<p class="wp-block-paragraph">“You’re a woman,” he said again. “I wrote some bad things about women wargamers once.” </p>



<p class="wp-block-paragraph">Gold recalls telling him, “You don’t need to feel embarrassed. I haven’t read them.” </p>



<p class="wp-block-paragraph">“You’re a woman,” Gygax repeated. Gold said goodbye and hung up. </p>



<p class="wp-block-paragraph">Despite being a role-playing game fan since issue 108 or so, I was never a subscriber to A&amp;E. I was nevertheless brought up short when I heard that A&amp;E was stopping. There is something truly remarkable about such epic persistence. </p>



<p class="wp-block-paragraph">There are longer-running projects, of course. The Herald, The Times and The Observer all date back to the late 1700s. The White Horse of Uffington, a monument in the Oxfordshire countryside, is 3,000 years old. Like a newspaper, it needs to be endlessly renewed or it will disappear. Indeed, as with A&amp;E, the community-building ritual required to scour the horse white may be more important than the physical product. In some cases, the process, rather than the result, is the purpose. </p>



<p class="wp-block-paragraph">Not always, though. At Rothamsted in Hertfordshire, crop experiments have been running continuously from the mid-19th century to investigate the long-term sustainability of certain farming practices. The Framingham Heart Study in the US has been studying the effects of diet, exercise and medications on heart disease since 1948, and is now looking at the grandchildren of the original 5,209 participants. In such endeavours, the longevity of consistent data is valuable in part because it is so unusual. </p>



<p class="wp-block-paragraph">But while scientific projects derive much of their value from sheer longevity, in the case of more human-scale creative projects there is something powerful about the fact that they simply cannot last for ever. The end of an endeavour such as A&amp;E, like the death of a centenarian, only serves to underline the achievement. </p>



<p class="wp-block-paragraph">A parallel that immediately sprang to mind was photographer Nicholas Nixon’s unforgettable series of portraits, The Brown Sisters. The first in the series was made at almost exactly the same moment as the first issue of A&amp;E, in the summer of 1975. Nixon captured four young sisters — Mimi, 15; Laurie, 21; Heather, 23; and his wife Bebe, 25. Every year, he made another group portrait. Each photograph is well-executed, but you wouldn’t necessarily look twice at it in a gallery. What is remarkable is the relentless passage of time, unsparingly recorded as the sisters pass 40, 50, 60. It’s a memento mori to beat any of those Renaissance depictions of skulls: you can’t look at the series without conjuring in your mind the first heartbreaking portrait in which only three sisters remain. </p>



<p class="wp-block-paragraph">“My intention would be that we go on for ever . . . just take three, and then two, and then one,” Nixon once said. But he stopped the project in 2022, with all four sisters still alive — if wrinkled and far closer into the lens. The project could have continued, I suppose. Nixon could have emulated the Framingham study and included children and grandchildren, recruiting his own replacement to make portraits until 2075 and beyond. But no: it is the contrast between the longevity of the work and the mortality of the subjects that gives the portraits so much power. </p>



<p class="wp-block-paragraph">A&amp;E, likewise, could have continued. It is after all a collective endeavour, the sum of all the fanzines within it. I asked Lisa Padol, a game designer and long-term A&amp;E contributor who assembled a collection of tributes to Lee Gold, why A&amp;E was stopping. She told me that Gold simply felt too much ownership to hand over the beloved name of Alarums and Excursions to someone else. </p>



<p class="wp-block-paragraph">That is understandable, but the work will continue under a new name: E&amp;A, or Ever and Anon. Perhaps it will become gaming’s Herald — or its Uffington White Horse?</p>
