Evidence Matters: The Ivory-Billed Woodpecker

Science doesn’t always work this way, but sometimes it does, and it would be good if it did more often.

The phonex had nothing on the ivory-billed woodpecker.
It is hard to keep track of how many times this near-mythic bird, the largest American woodpecker and a poignant symbol of extinction and disappearing forests, has been lost, and then found. Now it is found again.
Even the most skeptical ornithologists now agree. They say newly presented recordings show that at least two of the birds are living in Arkansas
Richard O. Brum, an ornithologist at Yale University and one of several scientists who had challenged the most recently claimed rediscovery of the ivory bill, said Monday after listening to the tape recordings that he was not “strongly convinced that there is at least a pair of ivory bills out there.”
Mark B. Robbins, an ornithologist at the University of Kansas, who had also been a skeptic, listened to the same recordings with a graduate students and said, “We were absolutely stunned.”

A Modest Proposal

Schools: Save cash
Teaching intelligent design exclusively would allow us to sell off a lot of “scientific” lab equipment and get rid of all of our grossly overpaid “science” teachers.
Imagine the savings if we could hire people who had the common sense to answer that “God did that” to every scientific inquiry. We don’t need to limit intelligent design merely to the question of the origins of humanity, either. It’s such a tidy theory that it can explain just about everything.
It can explain the 250,000 humans killed by the December tsunami. It can explain AIDS. It can explain cancer. It can explain 9/11.
Why bother studying anything at all when we already have the answer?

Private vs Public City Planning

Both private and public developers make judgments about the future market for their projects. When private developers’ judgments turn out to be wrong, they lose their money. When public developers’ judgments turn out to be wrong, they lose your money.

The Omaha By Design plan adopted by the City of Omaha envisions 72nd and Dodge framed with eight 10-story buildings and other taller structures stretching to a large residential complex at 76th Street. The drawings don’t resemble Bourn’s strip malls.
Wilke said he has seen the plan.
“That kind of visionary thinking is fun to engage in, but I don’t think it’s market-based,” he said. Another developer might see that as possible, he said, and Bourn Partners likes to do that kind of high-density, mixed-use development, but the company doesn’t see this part of the Omaha market as ready for that yet.
“We think the suburban scale is still what the market wants in that area,” Wilke said. (p. 2D)

Business at the city-owned Hilton Omaha is expected next year to fall $2 million short of generating the cash needed to cover its costs.
…
When the city built the hotel, predictions assumed that hotel revenues – not tax dollars – would be sufficient to pay it off.

Stealing Indian Land

These lands once belonged to the Kiowas and the Crows, but we whipped these nations out of them, and in this we did what the white men do when they want the lands of the Indians. We met the Kiowas and the Crows and whipped them at the Kiowa Creek, just below where we now are. We met them and whipped them again, and the last time at Crow Creek.

Downside of Air Conditioning

It is hard to come up with a case against air conditioning in August. But Burt Folsom managed to do so at a Young America’s Foundation gathering on 8/1/05 (broadcast on CSPAN-2 on 8/2) He pointed out that before air conditioning, the stifling heat of a D.C. summer drove Congress out of town. After air conditioning, Congress stayed in session longer, passing more laws.

Debreu on Danger of Over-Mathematization of Economics

From Debreu’s Presidential Address before the American Economic Association:

In the past two decades, economic theory has been carried away further by a seemingly irresistible current that can be explained only partly by the intellectual successes of its mathematization.
Essential to an attempt at a fuller explanation are the values imprinted on an economist by his study of mathematics. When a theorist who has been so typed judges his scholarly work, those values do not play a silent role; they may play a decisive role. The very choice of the questions to which he tries to find answers is influenced by his mathematical background. Thus, the danger is ever present that the part of economics will become secondary, if not marginal, in that judgment. (p. 5)

Tenure and the Market as Protectors of Free Thought

Mark Blaug as a young tutor at Queens College in New York, endorsed a student petition protesting the firing of a left-wing tenured professor for having refused to co-operate with the Un-American Activities Committee. Less than a day later, Blaug received a note from the President of Queens College, telling Blaug that his choice was either to resign or be fired. He resigned.
Fortunately, he received a grant from the Social Science Research Council to complete his dissertation, after which, again seeking employment, he obtained a job interview at Yale:

(p. 77) In the course of the interview, I felt impelled to explain how I had lost my previous teaching position at Queens College. I always remember how Fellner cut me off, saying: ‘We don’t want to hear about that. This is a private college and what transpired at a public university a few years ago is of no concern to us.’ I never had a better demonstration of Milton Friedman’s thesis that a free market, by multiplying the number of probable employers, is more likely to secure liberty for the individual than a socialist system in which the state is a monopsonist.
