Reading List for 16 July 2013

Evan Miller :: Winkel Tripel Warping Trouble or "How I Found a Bug in the Journal of Surveying Engineering"

All programming blogs need at least one post unofficially titled “Indisputable Proof That I Am Awesome.” These are usually my favorite kind of read, as the protagonist starts out with a head full of hubris, becomes mired in self-doubt, struggles on when others would have quit, and then ultimately triumphs over evil (that is to say, slow or buggy computer code), often at the expense of personal hygiene and/or sanity.

I'm a fan of the debugging narrative, and this is a fine example of the genre. I've been wrestling with code for mapping projections recently, so I feel Miller's pain specifically. In my opinion the Winkel Tripel is mathematically gross, but aesthetically unsurpassed. Hopefully I'll find some time in the next week or so to put up a post about my mapping project.

Kevin Grier :: Breaking down the higher ed wage premium

Wage premium and popularity of majors

File under "all college degrees are not created equal" or perhaps "no, junior, you may not borrow enough to buy a decent house in order to get a BA in psych."

Aleatha Parker-Wood :: One Shot vs Iterated Games

Social cohesion can be thought of as a manifestation of how "iterated" people feel their interactions are, how likely they are to interact with the same people again and again and  have to deal with long term consequences of locally optimal choices, or whether they feel they can "opt out" of consequences of interacting with some set of people in a poor way.

Mike Munger :: Grade Inflation? Some data

Munger links to some very good analysis but it occurs to me that what is really needed is the variance of grades over time and not just the mean. (Obviously these two things are related since the distribution is bounded by [0, 4]. A mean which has gone from 2.25 to 3.44 will almost certainly result in less variance here.)

I don't much care where the distribution is centered. I care how wide the distribution is — that's what lets observers distinguish one student from another. Rankings need inequality. Without it they convey no information.

Marginal Revolution :: Alex Tabarrok :: The Battle over Junk DNA

I share Graur's and Tabarrok's wariness over "high impact false positives" in science. This is a big problem with no clear solutions.

The Graur et al. paper that Tabarrok discusses is entertaining in its incivility. Sometimes civility is not the correct response to falsehoods. It's refreshing to see scientists being so brutally honest with their opinions. Some might say they are too brutal, but at least they've got the honest part.

Peter McCaffrey :: 5 reasons price gouging should be legal: Especially during disasters

McCaffrey is completely right. But good luck to him reasoning people out of an opinion they were never reasoned into in the first place.

I do like the neologism "sustainable pricing" that he introduces. Bravo for that.

I would add a sixth reason to his list: accusations of "price gouging" are one rhetorical prong in an inescapable triple bind. A seller has three MECE choices: price goods higher than is common, the same as is common, or lower than is common. These choices will result in accusations of price gouging, collusion, and anti-competitive pricing, respectively. Since there is no way to win when dealing with people who level accusations of gouging, the only sensible thing to do is ignore them.

Shawn Regan :: Everyone calm down, there is no “bee-pocalypse”

Executive summary: apiarists have agency, and the world isn't static. If the death rate of colonies increases, they respond by creating more colonies. Crisis averted.

Eliezer Yudkowsky :: Betting Therapy

"Betting Therapy" should be a thing. You go to a betting therapist and describe your fears — everything you're afraid will happen if you do X — and then the therapist offers to bet money on whether it actually happens to you or not. After you lose enough money, you stop being afraid.
