But I’ve seen maps that I find completely terrifying. Maps of uranium mining and of various illnesses in the Navajo reservations—they’re just insane. They just make you furious. Bill Bunge’s map—which I still think is one of the great maps, the map of where white commuters in Detroit killed black children while going home from work—that’s a terrifying map, and that’s an amazing map. He knew that. They had to fight to get the data from the city. They had to use political pressure to get the time and the exact location of the accidents that killed these kids. They knew what they were looking for. I didn’t have anything to do with that project, so when I saw the map for the first time, it was like, “Oh my god.” It’s so powerful to see maps like that. That’s the power of maps, or one of the powers of maps: to make graphic—and at some level unarguable—some correlative truth. We all knew that people go to and from work. But to lay the two things together reveals something horrible.

We’ve discussed before — in blog posts and a podcast — the value of a college degree. Writing for the New York Times Economix blog, Catherine Rampell points out that college degrees are particularly valuable in the U.S. “According to a report released this week by the Organization for Economic Cooperation and Development, across the developed world the average person who has graduated from college (either two-year or four-year) and has any earnings makes about 57 percent more than a counterpart with no more than a high school education,” writes Rampell. “In the United States, the comparable earnings premium is 77 percent.”
Despite the value of a college degree in the U.S., college graduation rates in the U.S. are increasing at a much slower pace than in other rich countries. And, as Rampell points out, it’s not just individuals in the U.S. that benefit from a college degree: “[T]he average return to taxpayers [of tertiary education for the average man] is $230,722 in the United States, versus less than half that, $104,737, across the developed world.”
Also: Oregon is thinking about letting students pay no college tuition, instead pledging a share of their future earnings. Lest you think this is straight out of Portlandia (like this is), know that Australia runs a similar college-tuition program.
A few years ago, we did a podcast on whether expensive wine tastes better. There is now further evidence that the answer to that question is no — even for elite wine critics. Winemaker Robert Hodgson recently collaborated with the California State Fair wine competition on a little wine-tasting experiment:

Each panel of four judges would be presented with their usual “flight” of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.
The first experiment took place in 2005. The last was in Sacramento earlier this month. Hodgson’s findings have stunned the wine industry. Over the years he has shown again and again that even trained, professional palates are terrible at judging wine.

Our Freakonomics Radio podcast “Women Are Not Men” mentioned that roughly 80 percent of lightning fatalities in the U.S. are men. A new National Weather Service report, summarized by io9, offers further details:
- Soccer players and fishermen are more likely to get hit by lightning than golfers.
- Saturday is the worst day of the week for lightning fatalities.
- July is by far the deadliest month for lightning deaths.

Wildlife activists have a new method for fighting Africa’s increasingly bold elephant poachers. Historically, scientists and governments have struggled to determine whether a piece of ivory was poached illegally or was obtained before the 1989 international ban on ivory trading, which has left some African governments with enormous stockpiles of ivory to manage and protect. But a team of scientists recently determined that it’s possible to use the amount of radiocarbon in an ivory tusk to determine what year the animal died — and, by extension, whether the ivory was illegally poached.
“The amount of radiocarbon in the atmosphere nearly doubled during nuclear weapons tests from 1952 to 1962, which steadily dropped after tests were restricted to underground. This has been dubbed ‘the bomb-curve,’” explains a BBC article on the study. The resulting significant variations in atmospheric radiocarbon allow for highly accurate dating. Scientists also hope that the technique will help shed light on poaching hotspots. Kevin Uno, the study’s lead author, told the BBC that the technique “would dovetail very nicely with DNA testing which tells you the region of origin, but not the date.”
The standard narrative around technology in the developing world usually focuses on the positive: cell phones make it easier to check crop prices, transfer money, and understand violence. But a new study, summarized in Foreign Policy, finds that all this connectivity can also increase political violence in violence-prone regions and countries:
A new study by Jan Pierskalla of the German Institute of Global and Area Studies and Florian Hollenbach of Duke University looks at the relationship between mobile phones and political violence in Africa. They found that from 2007 to 2009, areas with 2G network coverage were 50 percent more likely to have experienced incidents of armed conflict than those without. The clearest overlaps between cell coverage and violence were observed in Algeria, the Democratic Republic of the Congo, Kenya, Nigeria, Uganda, and Zimbabwe.
The authors think that improved cell-phone coverage helps insurgent leaders overcome what’s called the “collective-action problem” — that people are reluctant to join group endeavors when there’s a high level of personal risk. But better communication helps leaders recruit reluctant followers, whether they’re demonstrating for higher wages or killing people in the next town.
