"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.

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.
