Anthropologic

The 76 HackerNews comments do not review one product — they cover at least three anthropology-adjacent artifacts. (1) A BMJ-published essay by a clinical physiotherapist on 'primal' sleeping postures: top commenters (+128) call it 'a discursive, exploratory essay... in no way a scientific or quantified study,' noting the author admitted tribal surveys were 'meaningless' and that the paper's only citation is that humans are one of 200 primates. Yet another +128 commenter reports a multi-year n=1 trial: mattress topper on the floor, adopting the essay's figure 2.2 posture, 'never woke up sore, no matter where I slept'; another tried it for 5 minutes and confirmed the jaw 'closes naturally,' motivating a nose-breathing experiment. Skeptics (+128) counter that ground-sleeping is uncomfortable in almost any position, that hammocks undermine the primitive-bed narrative, and that 'what is wild?' is contested (Homo heidelbergensis built habitations ~700k years ago; ancient Greeks considered cities natural). (2) Erowid trip reports + a University of Amsterdam data-visualization project: commenters question verifiability ('How do the people who submit these reports know what they're using, and how much?'), while defenders note moderators triage out atypical reports and publish only ~1/3 of submissions for representativeness; one +55 commenter mourns Erowid 'going downhill' toward extreme polydrug stories, another rebuts that they simply moved from the Cannabis vault to the Datura vault. (3) David Graeber's anthropology of economics ('Debt: The First 5000 Years'): a +21 commenter suspects being 'played' by the Malagasy-probability anecdote ('Do Malagasies not gamble?'), while another celebrates the demolition of economics' barter founding myth. Net: substantive, self-correcting, citation-checking discussion — about anthropology as a topic, not any product.
