Einstein's IQ was never measured, 160 is only an estimate based on what he accomplished. When I was a bored 17-year old, I did online IQ tests for fun. I scored all over the map between 106 and 145. That really makes me question the reliability of such tests. Also, they usually only probe a small portion of what can be construed as intelligence (number and letter games, geometry stuff, differences between sets of items). I think intelligence is a lot more than that.
