Sorry, but, who measured this? Were they all subjected to an IQ test, or are they some bogus numbers as the IQ of Newton, Gauss and others that the one of the creators of the IQ tests made up?
This reminds me of a file that circulates on the net, purporting to be a ranking of the IQs of recent presidents. It's a political jab, but it gets passed around as if based on a real study of some kind. All the Democrats rank high, all the Republicans rank low, with George W the lowest of all, at below-average. It's completely bogus, but that doesn't stop people from circulating it. Perhaps this is the same.
