I’ve seen this study making the rounds on several websites now as a type of neuroeconomic confirmation of Buffetological principles…

Perhaps procedure might be slightly useful as a means of seeing physical brain improvement by training– such as that found through meditative practices.

“Traders who buy more aggressively based on NAcc signals earn less. High-earning traders have early warning signals in the anterior insular cortex before prices reach a peak, and sell coincidently with that signal, precipitating the crash. These experiments could help understand other cases in which human groups badly miscompute the value of actions or events.”

“Neuroeconomists Confirm Warren Buffet’s Wisdom”:

“Seeing what’s going on in people’s brains when they are trading suggests that Buffett was right on target,” says Colin Camerer, the Robert Kirby Professor of Behavioral Economics at Caltech.

That is because in their experimental markets, Camerer and his colleagues found two distinct types of activity in the brains of participants—one that made a small fraction of participants nervous and prompted them to sell their experimental shares even as prices were on the rise, and another that was much more common and made traders behave in a greedy way, buying aggressively during the bubble and even after the peak. The lucky few who received the early warning signal got out of the market early, ultimately causing the bubble to burst, and earned the most money. The others displayed what former Federal Reserve chairman Alan Greenspan called “irrational exuberance” and lost their proverbial shirts.
