Excellent exposé by Bishop Hill, about the carefully-diguised but fraudulent manipulation of data and preocessing, used to convince gullible people or those with little free time and a lot to do. Lots of useful embedded links to primary sources. Hat tip Samizdata, courtesy of Brian Mickelthwait, and I think the Englishman’s got his teeth into its ankle also. (Useful but slightly irrelevant, although amusing, links to all about Richard Dawkins included free if you see him.) You’ll all be pleased to see that The Devil has picked it up, too, and is somewhat less amused by the scale of the fraud even than I am!
And for some real dunking in proper coloured graphs and all that stuff, go to John Daly, here.
