Why computer models won't always work

Richard W. Rahn, chairman of the Institute for Global Economic Growth, writes in the Washington Times his commentary entitled "Model scams". He starts with this:

Experts use mathematical models to give us predictions about the future. Rank the following events according to the ability of the model builders to give accurate forecasts:

(A) The winner of the 2008 presidential election.

(B) The size of the U.S. budget deficit for the year 2009.

(C) The official low temperature in Chicago on April 1, 2008.

(D) The number of hurricanes that will strike Florida in 2010.

(E) The rise in the sea level over the next 100 years.

(F) The average temperature for the year 2100.


It's more towards the right on the global warming debate. But of course.
