Don't forget about the decent chunk that believe evolution occurs/occurred but was done or guided by a creator rather than natural selection as the mechanism (ignoring the subset that believe it's natural selection as designed by a creator, as they'd be in agreement in this particular case). Nobody really has a solid & reproducible answer for why the laws of the universe are the way they are, why any of it exists at all, or whether or not we'll be able to figure those things out with science or not. Just ways to try to figure out and assumptions at some point involving a leap of "and because that's just how it started and works. This reason it's that way makes the most sense to me so far". Personally I lean towards the belief and hope we'll one day be able to answer how things started in a reproducibly testable way using science but I don't necessarily consider that a prerequisite to thinking like a hacker. A hacker mindset, to me, is just that of one who wants to try and tinker with something to make it what they consider better or fun. You don't even need to be "correct" at your approach to figuring things out or successful in the outcomes, just believe you can try and tinker to make something better. I think certain types of other mindsets will make a more successful hacker, and they may disagree with what others think, but they aren't what I'd consider pre-requisites to thinking like a hacker.
Fair point on throwaways. I always call them throwaways out of lack of taking the time to think on what else to call them. "New accounts" feels wrong, even though technically accurate, as it can cause conflation with "new users". "Anonymous account" might be better phrasing for this case? I don't know if there is a more established term you/others use for accounts that hide community identity though. If there is please drop it in a reply so I can use that in the future.
However much I disagree with their reasons I don't necessarily think their comments make for bad discussion here or steer things in off-topic direction. A debate on what exactly this experiment is providing evidence of is good and healthy discussion of this article regardless which interpretation is correct, with those disagreeing the most likely to provide the critiques to consider. While they certainly aren't neutral positions (or ones I'd consider logical) that's not necessarily a mark of what's bad discussion or an excuse to announce I thought their comments were jokes/peddling. To us, some ideas offend, viewpoints alarm, or strike us as extremist - we don't have to treat those positions as neutral or valid but we should treat them kindly instead of always assuming the worst and commenting about it separately. That, ironically, is actually a distraction from discussion on the article (if you make a sincere Ask HN post about it some may be interested though).
