“Don’t Blink! The Hazards of Confidence” by Daniel Kahneman. This article appeared in The New York Times Magazine over a month ago and serves beautifully to make the point that the results of stock picking can be likened to “a dice rolling contest, not a game of skill.”

He also found that the average of the 28 correlations was .01 or zero. The outcomes were entirely down to chance not skill or judgement.
