Links 5/17: Rip Van Linkle | Slate Star Codex
More on Low-Trust Russia: Do Russian Who Wants To Be A Millionaire contestants avoid asking the audience because they expect audience members to deliberately mislead them?

Xenocrypt on the math of economic geography: “A party’s voters should get more or less seats based on the shape of the monotonic curve with integral one they can be arranged in” might sound like a very silly belief, but it is equivalent to the common mantra that you deserve to lose if your voters are ‘too clustered’”

Okay, look, I went way too long between writing up links posts this time, so you’re getting completely dated obsolete stuff like Actually, Neil Gorsuch Is A Champion Of The Little Guy. But aside from the Gorsuch reference this is actually pretty timeless – basically an argument for strict constructionism on the grounds that “a flexible, living, bendable law will always tend to be bent in the direction of the powerful.”

Otium: Are Adult Developmental Stages Real? Looks at Kohlberg, Kegan, etc.

I mentioned the debate over 5-HTTLPR, a gene supposedly linked to various mental health outcomes, in my review of pharmacogenomics. Now a very complete meta-analysis finds that a lot of the hype around it isn’t true. This is pretty impressive since there are dozens of papers claiming otherwise, and maybe the most striking example yet of how apparently well-replicated a finding can be and still fail to pan out.

Rootclaim describes itself as a crowd-sourced argument mapper. See for example its page on who launched the chemical attack in Syria.

Apparently if you just kill off all the cells that are growing too old, you can partly reverse organisms’ aging (paper, popular article)

The Politics Of The Gene: “Contrary to expectations, however, we find little evidence that it is more common for whites, the socioeconomically advantaged, or political conservatives to believe that genetics are important for health and social outcomes.”

Siberian Fox linked me to two studies that somewhat contradicted my minimalist interpretation of childhood trauma here: Alemany on psychosis and Turkheimer on harsh punishment.

Lyrebird is an AI project which, if fed samples of a person’s voice, can read off any text you want in the same voice. See their demo with Obama, Trump, and Hillary (I find them instantly recognizable but not at all Turing-passing). They say making this available is ethical because it raises awareness of the potential risk, which a Facebook friend compared to “selling nukes to ISIS in order to raise awareness of the risk of someone selling nukes to ISIS.”

Freddie deBoer gives lots of evidence that there is no shortage of qualified STEM workers relative to other fields and the industry is actually pretty saturated. But Wall Street Journal seems to think they have evidence for the opposite? Curious what all of the tech workers here think.

Scott Sumner: How Can There Be A Shortage Of Construction Workers? That is, is it at all plausible that (as help wanted ads would suggest) there are areas where construction companies can’t find unskilled laborers willing to work for $90,000/year? Sumner splits this question in two – first, an economics question of why an efficient market wouldn’t cause salaries to rise to a level that guarantees all jobs get filled. And second, a political question of how this could happen in a country where we’re constantly told that unskilled men are desperate because there are no job opportunities for them anymore. The answers seem to be “there’s a neat but complicated economics reason for the apparent inefficiency” and “the $90,000 number is really misleading but there may still be okay-paying construction jobs going unfilled and that’s still pretty strange”.

Study which is so delightfully contrarian I choose to reblog it before reading it all the way through: mandatory class attendance policies in college decrease grades by preventing students from making rational decisions about when and how to study.
