Abstract: There is a popular notion that hockey teams blow two-goal leads more often than they should. Hockey experts argue that teams with a two-goal lead tend to revert to a more defensive style of play and do so at their peril. We subjected the claim to National Hockey League data from the 2010 season and found that teams in such a predicament do not lose more often than they should. A possible explanation for the two-goal myth derives from the availability heuristic suggested by Kahneman and Tversky.
