Detroit? An Exception? Really?

SEE HERE  Cherry picking your data is a cardinal sin among scientists and economics counts rather more than most social sciences as a science.  Paul Krugman however Nobel Prize not withstanding plays fast and loose with data that doesn't fit his narrative.  Richard Feynman used to point out that it only takes one finding that doesn't fit the theory to overthrow a theory.  He obviously didn't have Paul Krugman on the job.  Krugman never found a fact that disproved his theories to be of any consequence.  That's the sign not of science but of dishonesty.
