I mentioned the IQ stuff because I found it to be a strange example. By definition of IQ, it shouldn't exhibit any issues so long as the random sampling is done correctly. In addition, there's a difference between saying "p is low so it is unlikely that the null is true" which is absolutely correct, and "1 - p is the probability the alternative hypothesis is correct". Certainly in physics people don't believe the second, I don't know about social sciences.
