People have gotten taller and healthier because of better nutrition, there is no reason to believe people haven't gotten smarter as well.

Null hypothesis? By default we don't assume presence of changes, in the absence of reasons for that, and those reasons - that nutrition is causing IQ growth - need to be explained.

There shouldn't be no reasons not to assume something, it's not enough. Sorry for triple negative.

This isn’t a by default issue, this is claiming counterevidence to increase in intelligence that justifies rejecting the validity of IQ in measuring intelligence because it is increasing. The null hypothesis doesn’t support that, only independent evidence of intelligence not increasing would.

by default we assume nothing, not a lack of change or interaction. to do the latter is to assert.

Some important factors in recent times are the awareness of iodine deficiency and the adverse effects of lead exposure.

It's important for many people's belief systems that intelligence is unaffected by physical/evolutionary factors.

It’s impossible to be politically correct these days unless you buy that theory.

The idea that evolution stops at the neck seems completely laughable to me.

According to Gwern's theory[0], there's no point dying on this hill right now as future genetic testing will illuminate reality.
