Psychology Professor Dr. Jordan B. Peterson gave a talk in March 2017 where he said (in the first minute of the video):
If you go back and look at the records at Harvard, for example, in the early 1960s, the typical IQ for a Harvard student was abouy 105 to 110 - not much above average. [...] Anyways the average Ivy League was bright, but not outstandingly so. Now, it is like an IQ of 145 - three standard deviations above the mean. The reason for that is that they are selected by the SAT.
But this blog article references a 2003 study suggesting the Harvard average is about 122.
Is there any conclusive data on this?
