The Counterintuitive World

Back during World War II, the RAF lost a lot of planes to German anti-aircraft fire. So they decided to armor them up. But where to put the armor? The obvious answer was to look at planes that returned from missions, count up all the bullet holes in various places, and then put extra armor in the areas that attracted the most fire.

Obvious but wrong. As Hungarian-born mathematician Abraham Wald explained at the time, if a plane makes it back safely even though it has, say, a bunch of bullet holes in its wings, it means that bullet holes in the wings aren’t very dangerous. What you really want to do is armor up the areas that, on average,Adon’t have any bullet holes.AWhy? Because planes with bullet holes in those places never made it back. That’s why you don’t see any bullet holes there on the ones that do return. Clever!

On a related note a related because it involves both an air force and some counterintuitive statistical reasoning a Henry Farrell writes about a passage from Justin Fox’sAMyth of the Rational Market involving the great behavioral economist Daniel Kahneman. Here is Kahneman reacting to an Israeli Air Force flight instructor who told him that whenever he chewed out a student he got better performance the next time out,Abut whenever he praised a student he got worse performance:

As a man trained in statistics, Kahneman saw thatAof course a student who had just brilliantly executed a maneuver (and was thus praised for it) was less likely to perform better the next time around than a student who had just screwed up. Abnormally good or bad performance is just that a abnormal, which means it is unlikely to be immediately repeated. But Kahneman could also see how the instructor had come to his conclusion that punishment worked. "Because we tend to reward others when they do well and punish them when they do badly, and because there is regression to the mean," he later lamented, "it is part of the human condition that we are statistically punished for rewarding others and rewarded for punishing them."

Would You Refuse to Hire Someone Wearing Dreadlocks?

TheAU.S. Equal Employment Opportunity Commission is suing aAVirginia moving and storage business for refusing to hire a man who wears his hair in dreadlocks because of his religious beliefs.

Christopher Woodson — who has 14 years of experience in the moving industry — applied for a job at Lawrence Transportation Systems in May 2008. The company wouldn’t hire him as a loader because Woodson refused to cut his hair, alleges a complaint filed inAU.S. District Court in Virginia. Woodson wears his hair in dreadlocks, because his Rastafarian religious beliefs encourage followers to refrain from cutting their hair.

Woodson offered to tie up his hair or wear a cap, according to the lawsuit. But aALawrence Transportationhiring official rejected Woodson’s offer, the lawsuit states. Woodson worked for Lawrence Transportation before he became a practicing Rastafarian in 2004.

The Quantum Mystics

Returning toAWhat the Bleep Do We Know? and similar materials, caution is well advised. Consciousness is not a part of regular textbook quantum mechanics nor is it clearly necessary to explain the logical and philosophical problems with quantum mechanics. It may be that we will one day find that mysticism, parapsychology, or some similar exotic idea is involved in quantum mechanics, but we do not know this today nor are we close to an answer.

Speaking mathematically, it may be possible to find the explanation for the quantum measurement problem by simply adding a non-linear term to the Schrodinger Equation that causes the collapse of the quantum wave function under certain physical conditions, most probably some sort of interaction between the wave functions of different particles. It is very hard to know what the precise form of this additional term might be. There have been a few attempts in the physics literature. Most likely it is necessary to think carefully about the conceptual issues swept under the rug in the quantum measurement operatorsA \hat T to make educated guesses about the nature of this term if it exists. It remains quite possible that solving these problems requires a radical change, discarding the Schrodinger Equation and other known mathematics almost entirely.

Why Pioneers Have Arrows In Their Backs

First-Mover Advantage is an idea that just won't die. I hear it from every class of students, and each time I try to put a stake through its heart.

Here's one more attempt in trying to explain why confusing testosterone with strategy is a bad idea.

The Haikyo Gallery (Ruins)

The Haikyo Gallery features the haikyo (ruins) explorations of blog authorAMichael John Grist in Japan.

'Haikyo' is a Japanese word that simply means ruin, or abandonment. They're the places that fell between the cracks; theAold mining town in the mountains that died when the copper seams ran dry, theAoutlandish theme park that failed when the Bubble burst, theAUS Air Force Base abandoned to nature's brambles.
