The Hamilton students sampled the predictions of 26 individuals who wrote columns in major print media and who appeared on the three major Sunday news shows – Face the Nation, Meet the Press, and This Week – and evaluated the accuracy of 472 predictions made during the 16-month period. They used a scale of 1 to 5 (1 being “will not happen, 5 being “will absolutely happen”) to rate the accuracy of each, and then divided them into three categories: The Good, The Bad, and The Ugly.
The students found that only nine of the prognosticators they studied could predict more accurately than a coin flip. Two were significantly less accurate, and the remaining 14 were not statistically any better or worse than a coin flip.
The top prognosticators – led by New York Times columnist Paul Krugman – scored above five points and were labeled “Good,” while those scoring between zero and five were “Bad.” Anyone scoring less than zero (which was possible because prognosticators lost points for inaccurate predictions) were put into “The Ugly” category.
