Nobel prize winners (especially those in math and sciences) tend to have IQs significantly above the population average.
There is no Nobel prize in math. And the word “especially” would imply that there exists data on the IQs of Nobel laureates in literature and peace which shows a weaker trend than the trend for sciences laureates; has anybody ever managed to convince a bunch of literature Nobel laureates to take IQ tests? I can’t find anything by Googling, and I’m skeptical.
To be clear, the general claim that people who win prestigious STEM awards have above-average IQs is obviously true.
(To be clear: I agree with the rest of the OP, and with your last remark.)
has anybody ever managed to convince a bunch of literature Nobel laureates to take IQ tests? I can’t find anything by Googling, and I’m skeptical.
I just read this piece by Erik Hoel which has this passage relevant to that one particular sentence you quoted from the OP:
Consider a book from the 1950s, The Making of a Scientist by psychologist and Harvard professor Anne Roe, in which she supposedly measured the IQ of Nobel Prize winners. The book is occasionally dug up and used as evidence that Nobel Prize winners have an extremely high IQ, like 160 plus. But it’s really an example of how many studies of genius are methodologically deeply flawed. …
Roe never used an official IQ tests on her subjects, the Nobel Prize winners. Rather, she made up her test, simply a timed test that used SAT questions of the day. Why? Because most IQ tests have ceilings (you can only score like a 130 or 140 on them) and Roe thought—without any evidence or testing—that would be too low for the Nobel Prize winners. And while she got some help with this from the organization that created the SATs, she admits:
The test I used is not one that has been used before, at least in this form.
And furthermore:
I was not particularly concerned at the outset over the fact that I had no norms for this test. That is, I had no idea what any other population would do on the same test.
In other words, she had an untested set of SAT questions that she gave to Nobel prize winners not knowing how anyone else would do on them. This is pretty problematic. Normally IQ tests try to achieve some form of group-level neutrality; e.g., many of the major modern IQ tests are constructed from the outset so as not show any average difference between male and female takers, to be as culturally-invariant as possible, etc. And while Roe didn’t publish without any comparison group to her chosen geniuses whatsoever, the comparison that she did use was only a graduating class of PhD students (sample size unknown, as far as I can tell) who also took some other more standard IQ tests of the day, and she basically just converted from their scores on the other tests to scores on her make-shift test of SAT questions. Yet, here are the raw numbers of how the Nobel-prize winners do on the test she created:
Notice anything? The Nobel Prize winners all scored rather average. In fact, pretty low, in some cases. But Roe then goes on to claim that their IQ is extremely high, based on her statistical transformations:
I must caution that these equivalents have been arrived at by a series of statistical transformations based on assumptions which are generally valid for this type of material but which have not been specifically checked for these data. Nevertheless I believe that they are meaningful and a fair guide to what the situation is. The median score of this group on this verbal test is approximately equivalent to an IQ of 166.
Wait a minute. How did this conversion to a median IQ of 166 take place? After all, the scientists are scoring in the middle of the range on the test. They are getting a lot of questions wrong. E.g., Biologists who won the Nobel Prize got a 56.6 on the Verbal but we know that was far from the maximum score, Experimental Physicists got an even lower 46.6, etc. How then did she arrive at the group altogether having an astoundingly-high median verbal IQ of 166? Assuming that those at the upper range of scoring got close to most of the questions right (she mentions this is true, some only missed 4-10 questions at the maximum range), then how can getting only roughly two-thirds of the questions right translate to an IQ in the 160s?
Perhaps these SAT questions were just impossibly hard? Judge for yourself. Here’s one of the two examples she gives of the type of questions the Nobel Prize winners answered:
In each item in the first section, four words were given, and the subject had to pick the two which were most nearly opposite in meaning and underline them.
Here is one of the items: 1. Predictable 2. Precarious 3. Stable 4. Laborious.
This. . . isn’t very hard (spoiler: 2 & 3). So the conclusion of a median verbal IQ of 166 is deeply questionable, and totally reliant on this mysterious conversion she performed.
This sort of experimental setup would never fly today (my guess is the statistical conversion had all sorts of problems, e.g., Roe mentions extraordinarily high IQ numbers for PhD students at the time that don’t make sense, like an avg. IQ of 140). A far more natural reading of her results is to remove the mysterious conversion and look at the raw data, which is that the Nobel-prize-winning scientists scored well but not amazingly on SAT questions, indicating that Nobel Prize winners would get test scores above average but would not ace the SATs, since the average was far below the top of the possible range.
(I don’t think Erik’s arguments here have any relevance whatsoever to the OP’s project though.)
It should be noted that the psychologists and anthropologists in the above tables were not selected based on winning a Nobel prize, nor any prize. On pages 51-52 of The Making of a Scientist Roe writes
For the psychologists the preliminary list was made up by me in consultation, separately, with Dr. E. G. Boring and Dr. David Shakow. We simply went over the membership list of the American Psychological Association and put down everyone we knew to be actively engaged in research and otherwise qualified. This preliminary list was then rated, in the usual fashion, by Dr. Boring, of Harvard University, [...]
and then lists a bunch of other professors involved in rating the list, and “the men who ranked at the top were selected, with some adjustment so as to include representatives of different sorts of psychology.”
(Incidentally, I wonder whether Professor Boring’s lectures lived up to his name.)
