Imagine you are choosing between two proposed road-improvement plans, but have the budget for only one. Both of the roads mooted for improvement are 20 miles long, and your sole aim is to reduce average journey time by as much as possible. Which would you choose? Someone travelling slowly to begin with has more time on the road to profit from any gain in speed 1) Improving Road A, which increases the average speed from 20 to 25mph (i.e. 25 per cent faster). or 2) Improving Road B, which increases the average speed from 40 to 65mph (62.5 per cent faster). The majority of people, including many experts, instinctively plump

The president of Stanford University, the neuroscientist Marc Tessier-Lavigne, has announced his resignation following an investigation into allegations of fraud and fabrication in three of his lab’s scientific papers, including one cited as the most important result on Alzheimer’s disease in 20 years. The report exonerated him of committing the fraud but found he had failed to correct the errors once they were brought to his attention.  The pandemic provided a glimpse of how far scientists will go to bend conclusions to a preferred narrative The vast majority of scientists are honest, but recent years have seen many cases of scientific misconduct come to the surface, implying there is a

Something weird is happening in the world of AI. On Jesus-ai.com, you can pose questions to an artificially intelligent Jesus: ‘Ask Jesus AI about any verses in the Bible, law, love, life, truth!’ The app Delphi, named after the Greek oracle, claims to solve your ethical dilemmas. Several bots take on the identity of Krishna to answer your questions about what a good Hindu should do. Meanwhile, a church in Nuremberg recently used ChatGPT in its liturgy – the bot, represented by the avatar of a bearded man, preached that worshippers should not fear death.  Elon Musk put his finger on it: AI is starting to look ‘godlike’. The historian

Everybody in racing is looking for an edge. With 7-4 the field, the punter is looking for a 2-1. The racecourse executive wonders which pop group will add 4,000 to the gate if booked for after-racing entertainment. The jockey on a confirmed front runner plans to slip the field out of the stalls. Trainers all seek an extra ingredient to help win them races consistently. At Sarsen Farm, a state-of-the-art new yard in Upper Lambourn built on the site of what was once a decrepit farmhouse then a Jockey Club tractor depot, Daniel and Claire Kubler are hoping that what a famous if ungrammatical advertisement for white goods used to

Here’s a paradox. Over the past two-and-a-half years, a cadre of senior politicians and their ‘expert’ advisers across the world have successfully promoted a series of controversial public policies by claiming they’re based on ‘the science’ rather than a particular moral or ideological vision. I’m thinking of lockdowns and net zero in particular. Yet at the same time, this group has engaged in behaviour that has undermined public confidence in science. Why appeal to the authority of science to win support for a series of politically contentious policies – and then diminish its authority? Take Anthony Fauci, for instance, who recently announced he’s stepping down as chief medical adviser to

Gstaad Who was it who said good manners had gone the way of black and white TV? Actually it was yours truly after watching the slobs parading up and down Gstaad’s main street. That was last year, but the bad news is that this year slobovia has come to stay again. Mind you, Alexandra and I had planned to have 50 friends for a party to celebrate 50 years of my enslavement, but Mister Omicron arrived and put a damper on our plans. The tent on the lawn and the oompah band were cancelled, and the New Year’s Eve blast turned into a smallish affair. The good news is that

More than anyone else, John von Neumann created the future. He was an unparalleled genius, one of the greatest mathematicians of the 20th century, and he helped invent the world as we now know it. He came up with a blueprint of the modern computer and sparked the beginnings of artificial intelligence. He worked on the atom bomb and led the team that produced the first computerised weather forecast. In the mid-1950s, he proposed the idea that the Earth was warming as a consequence of humans burning coal and oil, and warned that ‘extensive human intervention’ could wreak havoc with the world’s climate. Colleagues who knew both von Neumann and

Right from its first issue in 1823, the Lancet was more than just an ordinary medical journal. Its founding editor, the dyspeptic surgeon and coroner Thomas Wakley, purposefully gave the journal the name of a sharp scalpel that could cut away useless, diseased tissue: he used it as a campaigning organ, to push back against injustice, bad ideas and bad practice. What bothered Wakley most was the establishment. Not only did the Royal College of Surgeons care little about quacks and snake-oil salesmen, but its members were also engaged in corruption and nepotism, ensuring that their cronies got the best positions and filling their pockets with lecture fees. Wakley wrote
