• Not All Practice Makes Perfect
  Malcolm Gladwell’s written about Deliberate Practice, and he derived that term from work that this author has done. This author goes on to coin “Purposeful Practice”, which is kind of the same thing.

  We have especially strong evidence of this phenomenon as it applies to physicians. Research on many specialties shows that doctors who have been in practice for 20 or 30 years do worse on certain objective measures of performance than those who are just two or three years out of medical school. It turns out that most of what doctors do in their day-to-day practice does nothing to improve or even maintain their abilities; little of it challenges them or pushes them out of their comfort zones. For that reason, I participated in a consensus conference in 2015 to identify new types of continuing medical education that will challenge doctors and help them maintain and improve their skills.

• One Swede Will Kill Cash Forever—Unless His Foe Saves It From Extinction
  It seems like a no-brainer to move towards a cash-less economy – we’re most of the way there anyways. But this article talks about a compelling reason that a member of ABBA raised to push us towards that goal.

  In 2010, 40 percent of Swedish retail transactions were made using cash; by 2014 that amount had fallen to about 20 percent. More than half of bank offices no longer deal in cash. To his claim that going cashless is the “biggest crime-preventing scheme ever,” Ulvaeus now has some statistics to back it up. The Swedish National Council for Crime Prevention counted only 23 bank robberies in 2014, down 70 percent from a decade earlier. In the same period, muggings dropped 10 percent. While it’s unclear the extent to which the transition to cashless has affected the rate of street crime, police point out that there’s a lot less incentive to rob a bus driver, cabbie, or shopkeeper if they don’t accept cash.

• How game theory can help you do a better job of parenting
  This is an interesting idea for an article, but unfortunately the article is too short – giving only 3 examples of how game theory could be applied. Here’s one of them:

  Now let’s make it a bit more difficult. The cake is half chocolate and half vanilla. Your son loves chocolate; your daughter prefers vanilla. If your daughter cuts the cake in a way that gives each of them half of the chocolate and half of the vanilla, the cut is fair. Each piece is the same size. But neither child is entirely happy, because each got some cake they didn’t want. Turn the cut the other way – and divide it into a chocolate half for your son and a vanilla half for your daughter, and both are far happier. Both cuts were fair, but the cut into chocolate and vanilla halves demonstrated what’s called Pareto optimality. Each was not only fairly treated, but also got the best possible outcome.

• How Uber conquered London
  Yet another article about Uber, but this one covers a lot of things including how Uber started in London, and how drivers are paid.

  Driver No 1 was Darren Thomas. Before he joined Uber, most of his work came from Spearmint Rhino, the lap dancing club. Thomas had drifted back into chauffeuring after working for seven years as a salesman in the tiling industry. He signed up for as many hours as he could bear. “I absolutely caned it,” he told me. Soon he was earning £2,500 a week. On Uber’s first day in London, in the middle of June 2012, Howard had around 50 drivers on the platform. They did only 30 trips in 24 hours, but there was a single, glorious moment when seven rides were under way simultaneously and Kalanick happened to log in from San Francisco. “Travis was just blown away,” said Howard. “He was like, ‘Guys, look at London! This is unbelievable!’ It was just kismet, I guess.”

• No one ever says it, but in many ways global warming will be a good thing
  Interesting article about the benefits of global warming – the press always talks about the negative effects, but it turns out that the global warming will actually help the human race significantly as well.

  Similarly, we know that many more people die from cold than from heat. The biggest study on heat and cold deaths, published last year in Lancet, examined more than 74 million deaths from 384 locations in 13 countries from cold Sweden to hot Thailand. The researchers found that heat causes almost one-half of one percent of all deaths, while more than 7 percent are caused by cold.

  As global warming pushes temperatures up, more people will die in heat waves; a point emphasized by campaigners like UN climate chief, Christiana Figueres. What we don’t hear from her is that fewer people will die from cold. One study for England and Wales shows that heat kills 1,500 annually and cold kills 32,000. By the 2080s, increased heat-waves will kill nearly 5,000 in a comparable population. But ‘cold deaths’ will have dropped by 10,000, meaning 6,500 fewer die altogether.
