The Pundit’s Dilemma
There’s been a bit of a blogstorm over the impending release of the sequel to Freakonomics, the obviously-titled SuperFreakonomics. The authors are being taken to task for allegedly questionable science and statistics work, accused of oversimplifying or distorting their results for the sake of contrariness. There’s good discussion and links on Language Log’s post on the controversy:
Overall, the promotion of interesting stories in preference to accurate ones is always in the immediate economic self-interest of the promoter. It’s interesting stories, not accurate ones, that pump up ratings for Beck and Limbaugh. But it’s also interesting stories that bring readers to The Huffington Post and to Maureen Dowd’s column, and it’s interesting stories that sell copies of Freakonomics and Super Freakonomics. In this respect, Levitt and Dubner are exactly like Beck and Limbaugh.
We might call this the Pundit’s Dilemma — a game, like the Prisoner’s Dilemma, in which the player’s best move always seems to be to take the low road, and in which the aggregate welfare of the community always seems fated to fall. And this isn’t just a game for pundits. Scientists face similar choices every day, in deciding whether to over-sell their results, or for that matter to manufacture results for optimal appeal.
In the end, scientists usually over-interpret only a little, and rarely cheat, because the penalties for being caught are extreme. As a result, in an iterated version of the game, it’s generally better to play it fairly straight. Pundits (and regular journalists) also play an iterated version of this game — but empirical observation suggests that the penalties for many forms of bad behavior are too small and uncertain to have much effect. Certainly, the reputational effects of mere sensationalism and exaggeration seem to be negligible.

Ockham’s Broom
A new editorial series in the Journal of Biology, Ockham’s Broom:
Although it is increasingly difficult to gauge what people can be expected to know, it is probably safe to assume that most readers are familiar with Ockham’s razor – roughly, the principle whereby gratuitous suppositions are shaved from the interpretation of facts – enunciated by a Franciscan monk, William of Ockham, in the fourteenth century. Ockham’s broom is a somewhat more recent conceit, attributable to Sydney Brenner, and embodies the principle whereby inconvenient facts are swept under the carpet in the interests of a clear interpretation of a messy reality.
…
To elaborate that point briefly – While Ockham’s razor clearly has an established important and honourable place in the philosophy and practice of science, there is, despite its somewhat pejorative connotations, an honourable place for the broom as well. Biology, as many have pointed out, is untidy and accidental, and it is arguably unlikely that all the facts can be accounted for early in the investigation of any given biological phenomenon. For example, if only Charles Darwin had swept under the carpet the variation he faithfully recorded in the ratios of inherited traits in his primulas, as Mendel did with his peas, we might be talking of Darwinian inheritance and not Mendelian (see [3]). Clearly, though, it takes some special sophistication, or intuition, to judge what to ignore.

The Complete History of Lemmings We Did Manage
The Complete History of Lemmings.
We did manage to fox Psygnosis now and then, and I can lay claim that it took John White an hour to figure out “Its hero time”. When ever psygnosis did some testing, we’d get back a fax with the level name, time taken to complete, and some comments and a difficulty rating. These were usually aound 3-6 minutes, and some general coments on how they found it.
Every now and again though, the fax would be covered in scribbles with the time and comment’s crossed out again and again; this is what we were striving for while we were designing the levels, and it gave us all a warm fuzzy feeling inside.

Putting the Public Service back in PBS
Enjoyed this post on O’Reilly Radar advocating that PBS should realign with their original educational and public discourse mission. As local affiliates drop their secondary cable channels in favor of multiple over-the-air digital broadcasts, it’d be great to see at least one of those OTA channels used for stronger educational programming:
Our nation’s founders recognized that an educated public was crucial to the sustainability of American democracy, which led to public funding of education. Today, education happens in the media as well as in school. It is important that we use the media of television, in combination with new media, to support educational goals. There is even greater opportunity to combine a public broadcasting network and the interactive capabilities of the Internet to create a new hybrid framework for lifelong education.

In a spin: the mysterious dancing epidemic of 1518.
“In 1518, one of the strangest epidemics in recorded history struck the city of Strasbourg. Hundreds of people were seized by an irresistible urge to dance, hop and leap into the air. In houses, halls and public spaces, as fear paralyzed the city and the members of the elite despaired, the dancing continued with mindless intensity. Seldom pausing to eat, drink or rest, many of them danced for days or even weeks. And before long, the chronicles agree, dozens were dying from exhaustion. What was it that could have impelled as many as 400 people to dance, in some cases to death?”
See also: choreomania, the Tanganyika laughter epidemic of 1962 (the wonderful Radiolab did a segment last year about this), la danse macabre, and St. Vitus’ Dance, not to mention the final scenes of Bergman’s The Seventh Seal and Fellini’s 8½.

Near Real Time Face Detection on the iPhone Using OpenCV
Near real-time face detection on the iPhone using OpenCV. An obvious point to make, I know, but I still think it’s amazing that this would have been very difficult to do on any home computer just a few years ago but now our mobile devices can handle the task with relative ease.

CirculaFloor
From the SIGGRAPH 2004 emerging technologies demo, here’s the CirculaFloor, for when you want to play a bit of live-action Mario Bros. The tiles automatically rearrange themselves holonomically (albeit a bit slowly) depending on what direction the user is trying to walk.

Phillip Torrone Rides the Square Wheeled Tricycle
(video no longer available)
Phillip Torrone rides the square-wheeled tricycle from the Math Midway, a traveling exhibition of mathematics. Figuring out what kind of catenary curves would be needed for differently shaped wheels is a branch of mathematics that I’m happy exists (as far as I know the problem dates back on some level to the 1960s, but for a good recent illustration of the math involved, check out this PDF from a St. Norbert College mathematical modeling class).
