My Conversation with Tim Harford
Here is the transcript and audio, here is part of the summary:
Tim joined Tyler to discuss the role of popular economics in a politicized world, the puzzling polarization behind Brexit, why good feedback is necessary (and rare), the limits of fact-checking, the “tremendously British” encouragement he received from Prince Charles, playing poker with Steve Levitt, messiness in music, the underrated aspect of formal debate, whether introverts are better at public speaking, the three things he can’t live without, and more.
Here is one bit near the opening:
COWEN: These are all easy questions. Let’s think about public speaking, which you’ve done quite a bit of. On average, do you think extroverts or introverts are better public speakers?
HARFORD: I am an introvert. I’ve never seen any research into this, so it should be something that one could test empirically. But as an introvert, I love public speaking because I like being alone, and you’re never more alone than when you’re on the stage. No one is going to bother you when you’re up there. I find it a great way to interact with people because they don’t talk back.
COWEN: What other non-obvious traits do you think predict being good at public speaking?
HARFORD: Hmmm. You need to be willing to rehearse and also willing to improvise and make stuff up as you go along. And I think it’s hard for somebody to be willing to do both. I think the people who like to rehearse end up rehearsing too much and being too stiff and not being willing to adapt to circumstances, whereas the people who are happy to improvise don’t rehearse enough, and so their comments are ill formed and ill considered. You need that capacity to do both.
And another segment:
HARFORD: …Brian Eno actually asked me a slightly different question, which I found interesting, which was, “If you were transported back in time to the year 700, what piece of technology would you take — or knowledge or whatever — what would you take with you from the present day that would lead people to think that you were useful, but would also not cause you to be burned as a witch?”
COWEN: A hat, perhaps.
HARFORD: A hat?
COWEN: If it’s the British Isles.
HARFORD: Well, a hat is useful. I suggested the Langstroth beehive. The Langstroth beehive was invented in about 1850. It’s an enormously important technology in the domestication of bees. It’s a vast improvement on pre-Langstroth beehives, vast improvement on medieval beehives. Yet, it’s fairly straightforward to make and to explain to people how it works and why it works. I think people would appreciate it, and everybody likes honey, and people have valued bees for a long time. So that would have been my answer.
And:
COWEN: I’ve read all of your books. I’ve read close to all of your columns, maybe all of them in fact, and I’m going to ask you a question I also asked Reid Hoffman. You know the truths of economics, plenty of empirical papers. Why aren’t you weirder? I’ve read things by you that I disagreed with, but I’ve never once read anything by you that I thought was outrageous. Why aren’t you weirder?
The conversation has many fine segments, definitely recommended, Tim was in top form. I very much enjoyed our “Brexit debate” as well, too long to reproduce here, but I made what I thought was the best case for Brexit possible and Tim responded.
What I’ve been reading
1. Aladdin, a new translation by Yasmine Seale. A wonderful, lively small volume, a good reintroduction to the Arabian Nights, recommended.
2. Shalini Shankar, Beeline: What Spelling Bees Reveal About Generation Z’s New Path to Success. Not as analytical as I was wanting, but more analytical than I had been expecting.
3. Rowan Ricardo Phillips, The Circuit: A Tennis Odyssey. Provides a good look at the interior world of tennis competition, with emphasis on very recent times. A good look at how to think about the game, not only in the abstract, but as it plays out through the logic of particular events and tournaments.
4. Tim Smedley, Clearing the Air: The Beginning and the End of Air Pollution. Perhaps the best extant introduction to the air pollution issue, one of the world’s most important and underrated crises, and no I am not talking about carbon.
5. Gordon Peake, Beloved Land: Stories, Struggles, and Secrets from Timor-Leste. Mostly analytical, with real information blended with travelogue. I can’t judge the content, but I was never tempted to put this one down and throw it away.
6. Roderick Beaton, Greece: Biography of a Modern Nation. Excellent survey and overview, makes the late 19th century intelligible, among other achievements. “For Greeks, unlike the concept of the nation, the state had always been an object of popular derision.”
Will insects go extinct?
No, probably not, no matter what you might have read or seen on Twitter. The underlying paper is “Worldwide decline of the entomofauna: A review of its drivers.” Here is a tweet thread by Alex Wild on the paper, here is one bit:
They make a great deal of local extinctions as a sort of proxy for global extinctions. That’s pretty dicey. I mean, bison are locally extinct here in my Austin neighborhood. But their numbers are recovering elsewhere.
They used 73 studies done on different taxa in different places. Those studies must represent tens of thousands of person-hours. Gargantuan. But the input studies weren’t designed for global assessment.
The paper itself has strong evidence on the severe pressure on butterflies and bees, and furthermore the general encroachment of humans on the natural environment probably is going to diminish species numbers and biodiversity, for insects too. At the same time, the remaining species will adapt and evolve to meet the new potential habitats, with many kinds of insects having an easier time adapting than say gorillas.
The paper has some quite non-dramatic sentences such as: “Studies on ant populations and trends are lacking except for a few invasive species.” And: “A single long-term study on grasshoppers and crickets is available…”
So I don’t quite see how the authors arrive at: “The conclusion is clear: unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades.” Bryan Caplan, bet away!

Which are the most dangerous animals in America?
Beware the snake, the spider and the scorpion. But know this: You are much more likely to be killed by a bee or a dog.
Of the 1,610 people killed in encounters with animals between 2008 and 2015, 478 were killed by hornets, wasps and bees, and 272 by dogs, according to a study published in Wilderness & Environmental Medicine. Snakes, spiders and scorpions were responsible for 99 deaths over the eight years.
Using a database published by the Centers for Disease Control and Prevention, researchers found that 72 people annually were killed by “other mammals,” which includes horses, cattle and pigs.
Only six people a year died from snakebite, and six after being bitten by a venomous spider. Two people were killed by marine animals over the eight-year period, and no one was killed by a rat.

The return of Nigeria’s kidnapped girls
Joe Parkinson and Drew Hinshaw at the WSJ follow up on what was a super dramatic story that turned into a neglected and under-reported tale. What is life like for the Boko Harum kidnap victims after their liberation?
The women had acclimated to the forest camps where Boko Haram insurgents threatened them at gunpoint to either convert to Islam and marry a fighter or be a slave.
About half chose slavery, which cost them access to food and shelter.
Here is another bit:
Psychologists who specialize in kidnap victims say they are unsure about the best way to simultaneously treat and educate such a large group of women—ages 18 to 27—after years of collective captivity and abuse.
The spelling bee contests, one healing piece of the curriculum, arrived as something of a surprise. It was the Chibok girls who came up with the idea.
And:
One night, plopped on couches, they watched “Akeelah and the Bee,” a movie about an 11-year-old African-American girl in Los Angeles who finds her confidence after her father’s death by winning the Scripps National Spelling Bee.
The students watched the movie again and again over bowls of popcorn. They went to their teachers with a demand: They wanted to hold their own spelling bees. The teachers agreed.
The young women began memorizing vocabulary lists and testing each others’ lexicographic skills. Their wordplay escalated into late-night spelling battles. “It was unbelievably competitive,” Mr. Braggs said.
Spelling employs a skill many of the women honed while captive: mnemonic memory. Some spent much of their time memorizing lengthy prayers and hymns. Others composed diary entries in their heads—their thoughts, injustices they suffered—they would later log in journals they kept hidden. In secret, they retold the story of Job, the biblical figure who was punished in a test of his faith.
By the way, 112 girls remain missing and 13 are presumed dead.

Those new service sector jobs average is over spelling bee tutor edition
In the world of competitive spellers, Sylvie Lamontagne is known as a juggernaut. She placed fourth in last year’s Scripps National Spelling Bee, and ninth in 2015. Last summer, she traveled to California and won the Spelling Bee of China’s North America Spelling Champion Challenge, a contest for kids in the United States and China.
Now that the 14-year-old from Denver is no longer eligible to compete in this week’s National Spelling Bee at the Gaylord National Resort and Convention Center in Maryland — which is televised on ESPN and often turns kids like Sylvie into momentary celebrities — she’s focusing on a new vocation: spelling bee coach.
Sylvie’s rate? $200 an hour.
Hiring coaches isn’t new. But bee aficionados say a recent surge in competition, and a tightening of rules meant to limit co-champions, has spawned a demand for younger coaches such as Sylvie: high-schoolers or college kids, months or just a few years into their bee retirement, who can pass along fresh intelligence on words to memorize and how to decode bizarre words based on their language of origin.
That is from Ian Shapira at WaPo.
Not exactly St. Francis talking to the birds, in fact it is more useful
This is remarkable:
Now scientists have determined that humans and their honeyguides [a kind of bird] communicate with each other through an extraordinary exchange of sounds and gestures, which are used only for honey hunting and serve to convey enthusiasm, trustworthiness and a commitment to the dangerous business of separating bees from their hives.
The findings cast fresh light on one of only a few known examples of cooperation between humans and free-living wild animals, a partnership that may well predate the love affair between people and their domesticated dogs by hundreds of thousands of years.
Claire N. Spottiswoode, a behavioral ecologist at Cambridge University, and her colleagues reported in the journal Science that honeyguides advertise their scout readiness to the Yao people of northern Mozambique by flying up close while emitting a loud chattering cry.
For their part, the Yao seek to recruit and retain honeyguides with a distinctive vocalization, a firmly trilled “brrr” followed by a grunted “hmm.” In a series of careful experiments, the researchers then showed that honeyguides take the meaning of the familiar ahoy seriously.
…Researchers have identified a couple of other examples of human-wild animal cooperation: fishermen in Brazil who work with bottlenose dolphins to maximize the number of mullets swept into nets or snatched up by dolphin mouths, and orcas that helped whalers finish off harpooned baleen giants by pulling down the cables and drowning the whales, all for the reward from the humans of a massive whale tongue.
But for the clarity of reciprocity, nothing can match the relationship between honeyguide and honey hunter. “Honeyguides provide the information and get the wax,” Dr. Spottiswoode said. “Humans provide the skills and get the honey.”

The Sharks Get Stung
On Friday, Shark Tank, the investment television show, featured two nice ladies from Minnesota and their product Bee Free Honee, honee made from apples. Is cheap, vegan honee a good idea? Perhaps but I was less than convinced by one of the arguments the ladies made for their honee–it will save bees! The ladies argued that reducing the demand for honey will encourage bee farmers to not work the bees so hard thus increasing their numbers.
I was expecting the acerbic Kevin O’Leary to have a field day with this economic fallacy. Or maybe, I thought, Mark Cuban will throw a dash of common sense into the tank. But no, all the Sharks cooed about this mad scheme. So it is up to me.
Reducing the demand for honey, reduces the demand for honey bees. A cheap, high-quality substitute for honey doesn’t mean a world of bees gently pollinating flowers in an idyllic landscape it means a beepocolypse. Bee free honee will save bees the same way the internal combustion engine saved horses.
Addendum 1: You may be concerned about colony collapse disorder. Well, the commercial beekeepers are even more concerned and they have been adapting to CCD and maintaining honey production and pollination services. In fact, there are more bee colonies in the United States today (latest data) than there have been anytime in the last 20 years. CCD is still a problem but it’s the demand for honey and pollination services that incentivizes solutions to the problem. Remember, without honey it’s only a hobby.
Addendum 2:Perhaps the ladies have a sophisticated position on the repugnant conclusion but I doubt it.
Hat tip: Max.

Markets in everything, hunting mutant animals edition
More than 99.9 percent of all wild gnus, also called wildebeest, from the Afrikaans for “wild beast,” have dark coats. But this three-year-old golden bull and his many offspring are not an accident. They have been bred specially for their unusual coloring, which is coveted by big game hunters.
These flaxen creatures are the latest craze in South Africa’s $1 billion ultra-high-end big-game hunting industry. Well-heeled marksmen pay nearly $50,000 to take a shot at a golden gnu — more than 100 times what they pay to shoot a common gnu. Breeders are also engineering white lions with pale blue eyes, black impalas, white kudus, and coffee-colored springboks, all of which are exceedingly rare in the wild.
“We breed them because they’re different,” says Barry York, who owns a 2,500-acre ranch about 135 miles east of Johannesburg. There, he expertly mates big game for optimal — read: unusual — results. “There’ll always be a premium paid for highly-adapted, unique, rare animals.”
…No one disputes that there’s money to be made in rare big game. Africa Hunt Lodge, a U.S.-based tour operator, advertises “hunt packages” to international clients traveling to South Africa that include killing a golden gnu for $49,500, a black impala for $45,000, and a white lion for $30,000.
There is more here, and for the pointer I thank Kaushal Desai.
