Jacob Barnett has an IQ of 170 - higher than Albert Einstein
...Einstein never took an IQ test...
No, but scientists have fairly accurate methods of determining people's IQ's by looking at their achievements. Einstein's IQ was estimated to be around 160.
I'm always very cautious though when I see those statements about those high IQs. Problem is, the IQ scale follows a bell curve, and as such the more you deviate from the mean, the fewer and fewer amount of data defines a certain IQ segment.
To use the math, the IQ's bell curve is defined to have a standard deviation of 15. So, an IQ 170 is 4.6 standard deviations away from the mean, which in turn means 0.0019% of the population that have an IQ of 100. Obviously, 0.00019% isn't a lot of people, meaning this part of the IQ curve is defined by a handful of individuals and thus not really statistically significant.
I mean, there's no question these people have a way higher IQ than the average person, but the discussion of whether Einstein or this kid has a higher IQ is statistically a moot discussion. (to go completely technical, the problem is that the size of the confidence interval increases the further away from the mean you get. At 5 standard deviations away the confidence interval is quite likely much bigger than the difference in Einstein's and the kid's IQ).
