Exactly. And I've never even seen the p-level of these studies stated
in anything I've read about them, nor have I ever seen plots of the
distributions of test scores. It's not as if the journalists think
the public won't understand the p-level, because the NY Times, at least,
states it and explains it when they report the results from one of
their political surveys.
