This is cool:
India’s public karaoke-for-literacy experiment is the only one of its kind in the world. Technically known as same-language subtitling, or SLS, it manages to reach 200 million viewers across 10 states every week. In the last nine years, functional literacy in areas with SLS access has more than doubled. And the subtitles have acted as a catalyst to quadruple the rate at which completely illiterate adults become proficient readers.
This whole piece from Intelligent Life is great (the best thing I’ve read on the topic, far better than the essay I’ve been failing to write), but this bit is at the root of the science skepticism I feel lacking in public discussion:
If the past is any guide—and what else could be?—plenty of today’s science will be discredited in future. There is no reason to think that today’s practitioners are uniquely immune to the misconceptions, hasty generalisations, fads and hubris that marked most of their predecessors.
One obvious trait that the MBTI has in common with horoscopes is its tendency to describe each personality type using only positive words. Horoscopes are so popular, in part, because they virtually always tell people just what they want to hear, using phrases that most people generally like to believe are true, like “You have a lot of unused potential.”
An interesting idea from David Brooks:
If you look at America from this perspective, you do see something akin to the “British disease.” After decades of affluence, the U.S. has drifted away from the hardheaded practical mentality that built the nation’s wealth in the first place.
The shift is evident at all levels of society. First, the elites. America’s brightest minds have been abandoning industry and technical enterprise in favor of more prestigious but less productive fields like law, finance, consulting and nonprofit activism.
There are few things that environmental activists have enjoyed attacking more in the last decade than meat, and so to see one of them reconsider that is nice.
If pigs are fed on residues and waste, and cattle on straw, stovers and grass from fallows and rangelands – food for which humans don’t compete – meat becomes a very efficient means of food production. Even though it is tilted by the profligate use of grain in rich countries, the global average conversion ratio of useful plant food to useful meat is not the 5:1 or 10:1 cited by almost everyone, but less than 2:1. If we stopped feeding edible grain to animals, we could still produce around half the current global meat supply with no loss to human nutrition: in fact it’s a significant net gain.
It should be noted, however, that this theoretical world where ideal meat-raising is practiced is quite different than the methods currently used to do so.
