“In life as in poker, the occasional coup does not necessarily demonstrate skill and superlative performance is not the ability to eliminate chance, but the capacity to deliver good outcomes over and over again. That is how we know Warren Buffett is a skilled investor and Johnny Chan a skilled poker player.” — John Kay, Financial Times
This made me think of a sports gambling database and strategy set that I read about in an ESPN magazine at a barber shop. I don't remember the specifics but I recall that the database was shared by invitation only and had an intentional "barrier to entry" level buy in, which seemed high to me. The article claimed the database was in use by only 9 professional gamblers. I'd like to see some performance data on their bets.
The minus one must be for not seeing two fallacies and a bias in such a pretty package. Oh well, can't win em all.
