This is demonstrably untrue. IQ has increased consistently for decades, far faster than genetic factors can explain. Environmental factors like education, nutrition, and medical care are the obvious explanation.

This also assumes that IQ testing has remained static. It has not. IQ tests continue to evolve and there are >1 of them and they do not all agree. I.E. the tests themselves might be responsible for some of the variance.
how does one separate "doing good" and "stop doing harm"?
I'd personally count nutrition squarely in the second category
The recent marathon world records are apparently due to improved nutrition.
Here's the producer of the hydrogels talking about the exact process of getting the maximum carbohydrates into the runner:

> At the elite level, marathon performance is defined by energy availability as much as physiology.
> Maintaining a pace of 2:50 per kilometer requires a constant supply of fuel. Even small disruptions in energy delivery can result in significant time loss.
coppsilgold is the one who made a hard-line, clear-cut dichotomy when they said "it's easy to do harm [but] it's all but impossible to do any good". bglazer referenced several interventions that are known to increase IQ which challenge this dichotomy. Saying that it is difficult to separate "doing good" and "stop doing harm" is agreeing with the point that coppsilgold created a distinction without a difference.
Also we are past that. Now IQ started decreasing.
it's hard to separate IQ decreasing and return to mean with IQ stabilizing
in 20th century most of the world moved past famine and toxins - did any factor of similar scale happen in 21st century as well to start looking for opposite processes?
Generally that statistic refers to populations in isolation, not the entire world in aggregate.
It is fairly well agreed upon that American kids across the nation are currently testing lower than they were in 2010.
