There doesn't need to be an evolutionary advantage for everything (e.g. vestigal features) - this "uncertainty-blindness" could have just not been exposed to evolutionary pressure.
- nommm-nommm 10y agoVery few 70+ year olds are reproducing so evolutionary advantage doesn't make sense in that age group as they have already reproduced (or not) by then.
- JoeAltmaier 10y agoHistorically the aged sat around the fire and taught the young. Which encouraged their genes' propagation. Since Humans became social, its not been all about reproduction.
- bakhy 10y agothis is all extremely speculative, of course! but i would say that anything that affects your thinking can pose an evolutionary advantage or disadvantage. (to also answer a peer comment here:) including when you are past your reproductive age, since human beings are social beings, and our evolution cannot be regarded purely individualistically. to give an extremely stupid, but i hope illustrative example, a society where the old people go extremely stupid and start killing people around them is going to have a hard time ;)
