It's actually very difficult to prove that something is genetically heritable vs heritable through other means including diet, medicines, etc. Especially when you want to account for effects in the womb, where you can't do twin studies. Even things like height and IQ, it's not clear how the heritability is passed on, much less something as complicated as high functioning autism.
Science is difficult, yes. Otherwise, no. We know a lot and with high certainty.
I think it’s harmful to pretend that reality is inscrutable and that science struggles to give answers. It’s fuel for the RFK Jr type of societal parasite.
We do not in fact know with high certainty the amount of genetic causality in IQ (or the broad validity of IQ itself, but stipulate that isn't a problem). Molecular genetics has shaken things up over the last 8-10 years.
Pretending that we know a lot about something with high certainty so that you can get a one up on RFK Jr types is much more harmful, especially on the long term. The anti RFK Jr types end up being distrusted and put in the same bucket as the RFK Jr types for spreading misinformation.
There are people distrustful of those who proclaim the earth round. There is no threshold of certainty where unreasonable skepticism will be eliminated, science is a tool for the reasonable.
It's not misinformation. Reasonable people know that science determining something is true only means the current evidence strongly indicates its true, and that future results may call anything into question, but we should not expect any particular current finding to be false. It is misinformation to characterize the lack of absolute certainty, which is something science can never produce, as indicative that claims differing from the scientific consensus are equally supported by the evidence.
You don't need to worry about people losing trust in science because science does not require trust. Those who are unsatisfied with anything less than certainty need something other than science.
Cool story, but I don’t really lose any sleep over anti-science idiots prompting themselves into sustained relevance over the long term, short term, or even the next electoral term, really.
