Most of the planet refused to wash their hands or use basic sanitation until about 150 years ago even though they had clear reproducible evidence doing so saved countless lives 50 years earlier. Most just considered doing the bare minimum to save lives as too much work. Also we used to advertise cigarettes and alcohol for consumption by babies in the 50s.

It is reasonable to assume the majority of humans are intellectually lazy to the point of killing themselves and their families if told to with the right marketing.

We should all make our own individual well researched choices and not ever buy into the worthless argument of "everyone does it".
