Fascinating discussion via Wired‘s Clive Thompson, and Stanford historian of science Robert Proctor, on Agnotology:
“When it comes to many contentious subjects, our usual relationship to information is reversed: Ignorance increases.
[Proctor] has developed a word inspired by this trend: agnotology. Derived from the Greek root agnosis, it is “the study of culturally constructed ignorance.”
As Proctor argues, when society doesn’t know something, it’s often because special interests work hard to create confusion. Anti-Obama groups likely spent millions insisting he’s a Muslim; church groups have shelled out even more pushing creationism. The oil and auto industries carefully seed doubt about the causes of global warming. And when the dust settles, society knows less than it did before.
“People always assume that if someone doesn’t know something, it’s because they haven’t paid attention or haven’t yet figured it out,” Proctor says. “But ignorance also comes from people literally suppressing truth—or drowning it out—or trying to make it so confusing that people stop caring about what’s true and what’s not.” (emphasis added)
Fairly amazing, and when it comes to certain issues, its dead on.
What an awesome definition:
Agnotology: Culturally constructed ignorance, purposefully created by special interest groups working hard to create confusion and suppress the truth.

Part of the story about the Madoff Ponzi scheme was that Madoff created this elusive, difficult-to-become-a-member club. The exclusivity and rejections made membership all the more desirable to greedy investors. That actually is turning out to be somewhat of a myth. There is much more to his canny trick of rejecting investors than initially meets…Read More
Last night’s 60 Minutes had a story on Oil Speculation. Its not that they said anything that was factually wrong per se, its more that they told 10% of the story of the rise and fall of energy prices. The entire report was surprisingly thin, and avoided discussing all of the many other factors that…Read More
The Treasury Department TARP/Bailout plan has been an utter disaster. It has been mishandled from day one — poorly planned, poorly executed. Both Hank Paulson and Congress for passing such a shoddy piece of legislation should be ashamed of themselves for their horrific judgment and egregious failures. It is hard to see a single thing…Read More

Here is another excerpt — part II — of the all consuming OpEd of the Sunday New York Times by Michael Lewis and David Einhorn: Excerpt: When Bear Stearns failed, the government induced JPMorgan Chase to buy it by offering a knockdown price and guaranteeing Bear Stearns’s shakiest assets. Bear Stearns bondholders were made whole…Read More
The entire OpEd section of the Sunday New York Times has been taken over by an article jointly written by Michael Lewis and David Einhorn, titled The End of the Financial World As We Know It.

Terrific l o n g article in the Sunday Times Magazine by Joe Nocera, titled Risk Mismanagement. Its all about how Wall Street developed and still uses VaR — Value at Risk.
The application of VaR remains hotly debated today. Did it contribute to the credit crisis — or was it ignored/misapplied/distorted, and THATS what was a key factor.
Risk managers use VaR to quantify their firm’s risk positions to their board. In the late 1990s, as the use of derivatives was exploding, the Securities and Exchange Commission ruled that firms had to include a quantitative disclosure of market risks in their financial statements for the convenience of investors, and VaR became the main tool for doing so. Around the same time, an important international rule-making body, the Basel Committee on Banking Supervision, went even further to validate VaR by saying that firms and banks could rely on their own internal VaR calculations to set their capital requirements. So long as their VaR was reasonably low, the amount of money they had to set aside to cover risks that might go bad could also be low.
Given the calamity that has since occurred, there has been a great deal of talk, even in quant circles, that this widespread institutional reliance on VaR was a terrible mistake. At the very least, the risks that VaR measured did not include the biggest risk of all: the possibility of a financial meltdown. “Risk modeling didn’t help as much as it should have,” says Aaron Brown, a former risk manager at Morgan Stanley who now works at AQR, a big quant-oriented hedge fund. A risk consultant named Marc Groz says, “VaR is a very limited tool.” David Einhorn, who founded Greenlight Capital, a prominent hedge fund, wrote not long ago that VaR was “relatively useless as a risk-management tool and potentially catastrophic when its use creates a false sense of security among senior managers and watchdogs. This is like an air bag that works all the time, except when you have a car accident.” Nassim Nicholas Taleb, the best-selling author of “The Black Swan,” has crusaded against VaR for more than a decade. He calls it, flatly, “a fraud.” . . .
What will cause you to lose billions instead of millions? Something rare, something you’ve never considered a possibility. Taleb calls these events “fat tails” or “black swans,” and he is convinced that they take place far more frequently than most human beings are willing to contemplate. Groz has his own way of illustrating the problem: he showed me a slide he made of a curve with the letters “T.B.D.” at the extreme ends of the curve. I thought the letters stood for “To Be Determined,” but that wasn’t what Groz meant. “T.B.D. stands for ‘There Be Dragons,’ ” he told me.
Best line in the article: “When Wall Street stopped looking for dragons, nothing was going to save it.”
I particularly loved the graphics and illustrations that were part of it:
Paul Krugman asks: Unusually, I’m having a vocabulary problem. There has to be some word for the kind of person who considers his mild discomfort the equivalent of torture, crippling injury, or death for other people. But I can’t think of it. What brings this to mind is this from Alberto Gonzales: I consider myself…Read More
