I don't particularly trust it.
For one thing, in the section that includes people who are alive today, 12 out of 15 are listed as "allegedly" having a particular IQ, only 3 of them actually had their IQ scores verified. So for the great bulk of people on that list, we have no way of knowing what their actual IQ is.
I would also be curious to know if the personality types assigned to the people who are still alive, have been given to them as a result of them being tested, or is it just a guess that they have that particular personality type. I can say for sure that for almost all the people on that list who are no longer alive, the personality type assigned to them is purely a guess, so is not reliable at all.
