anyone know anything about error rates in calendrical timekeeping? like, archaeologically / anthropologically / ethnographically… if i were in a cave scratching the wall, what'd be my day-slip rate? what about a society of 100 ppl? it goes so low so fast! we are a GREAT clock!
Yeah full deprivation would totally screw you up. The studies I’m thinking of were more controlled. I have the refs somewhere. Something where you had control over artificial lighting etc I think. Body clock entrainment works only with some solar wavelengths or something

That seems plausible. I wonder how groups of various sizes would sync if they didn’t have external cues but did have each other.

This has some details. The book Rhythms of Life had a very detailed neuroscience explanation that I’ve now mostly forgotten. https://en.m.wikipedia.org/wiki/Circadian_rhythm …
