Einstein's IQ was just about 160. People think he had a really high IQ but it isn't really high. I think I read about a week ago that Bill Clinton's was higher.
160 is extremely high, but since Einstein never took a standard IQ test, no one knows what his was. It is safe to assume he was far smarter than your average bear.
We recently dealt on this board with the hoax about Bill Clinton's supposed 182 IQ, but I believe it was deleted. Here it is again for whatever it's worth and for as long as it lasts.
