What I'm getting from all this is that we have an armchair expert explaining details about something they're not an expert in, and we have you reviewing the way they present this information, saying their very weak hedge wasn't strongly negative enough. Based on priors about the industry.
Basically, HN doing HN things - having a good deep think about topics outside their realm of expertise, then debating the minutiae. I'd just rather trust someone who has spent their career researching this stuff, thanks (unless that's what you do - in which case please tell us more).
It may be minutiae, but olooney’s point is valid: the evidence doesn’t seem to support saying “maybe a little”. Remove that statement from the conclusion and it’s on the right track, aside from the arbitrary IQ point calculation which is nonsensical.
"HN doing HN things" over someone saying "good discussion, however, one point about the conclusion" and having that point be very rational and still open to debate.
Is discussing such secondary but still highly relevant aspects verboten? Must every comment here be by a lead researcher in the specific field? Would a biomedical science researcher necessarily have any more expertise on these important secondary aspects?
"Trust me, I'm a scientitian". No thanks.
