For those looking for more than a pithy comment, check out the book "The Bell Curve Debate". IQ was a retrofit system intended to be a "predictor of many personal outcomes, including financial income, job performance, birth out of wedlock, and involvement in crime".
I mean, it's not that I doubt increases in IQ are possible. Let's be generous. Now what? To what extent can IQ change? Can I increase it without bound? To what extent are the changes permanent? To what extent are they reproducible? Can we train a person who might count as mentally disabled to score significantly higher on the test? If not, why not? Has the author tried? Does the author think nobody else has studied this? If the results aren't reproducible, then what are we to gain from this?
If you want to speak on scientific matters, you should probably do science.
the author only provides vague statements such as "it was a pleasant experience" or "slightly reduced exercise", and ends it with "read about this topic".
so there's no question of reproducibility since there is no method to reproduce.
this is the equivalent of a scientist submitting a paper for publication with one sentence in Materials & Methods section: "we will let the readers infer the exact steps based on our conclusions"
Did add a quick explanation about methods at the end ... I forgot that when I say "you can read the science around this topic to see how" and provide some links to examples of papers, people don't actually do it.
it's more like, in a world with thousands of oncologists that treat pancreatitis cancer, saying: You should go to one, I'm not going to recommended mine in particular, but I went to one and she cured my cancer, so maybe you should give it a shot.
