Now a group of college kids studied the talking-heads in print and on the air, and here is what they found, according to a study reviewed by John Amato over at Crooks and Liars. Click on the link to read more.
Op-ed columnists and TV's talking heads build followings by making bold, confident predictions about politics and the economy. But rarely are their predictions analyzed for accuracy.
Now, a class at Hamilton College led by public policy professor P. Gary Wyckoff has analyzed the predictions of 26 prognosticators between September 2007 and December 2008.
-----------------------
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. Syndicated columnist Cal Thomas came up short and scored the lowest of the 26.
----------------------------------
Those scoring lowest - "The Ugly" - with negative tallies were conservative columnist Cal Thomas; U.S. Senator Lindsey Graham (R-SC); U.S. Senator Carl Levin (D-MI); U.S. Senator Joe Lieberman, a McCain supporter and Democrat-turned-Independent from Connecticut; Sam Donaldson of ABC; and conservative columnist George Will.
