How do you propose I respond to your answer? I asked for clarification and you replied with a troll response. How would you respond if I did the same?

Sorry about that. The point is, at least by now, HBD is a thoroughly confusing term that gets used in many, sometimes mutually contradictory ways. The SSC community has spent many years trying to handle the multiple sides of the many "nature vs. nurture" debates that are also referenced in OP's article, and ultimately decided that the 'HBD' term itself was not very helpful to that end. To ask for a "clarifying definition" of HBD given these circumstances is indeed rather pointless.

Ok. That's a reasonable answer and I recommend assuming good faith next time and not trolling.
