Are you saying this with a straight face

Ok, what?

People have always had selfish members of the populous and others who vote against their own interests, as you've described. These are not as surprising or absurd as default-circumcision. I'm not saying they're less harmful or less important -it would be a near miracle if we could counter the malicious neglect of the needy and ignorant voting patterns. But there's not a high-contrast there, the way there is with hospitals defaulting to circumcision. The fact that voting isn't 'done well' and that many people don't care about climate health isn't exactly surprising. Psychologist Dan Ariely has quipped that climate issues are practically perfect in terms of not eliciting human concern: much of it is gradual and thus hard to detect contrast, it feels far off in the future, and many of the alarming cases in other territories are far away and thus don't feel immediate. Therefore, it's not surprising that this doesn't motivate people as it should. Thankfully, people are trying to solve that issue; but I bring it up to show that it's not a head-scratcher of high contrast.

I think you took my statement to mean that it's surprising that civilized societies like ours do circumcision. That's not what I meant, I meant only that circumcision is one of those few things that is a very high-contrast head scratcher: pervasive yet superfluous, only justified by culture at this point, yet it was a default in hospitals where we picture medical practitioners bypassing conventions. Another one is factory farming, where other species are robbed of their lives and live a life in miserable conditions, mostly just because humans like the 'taste' and 'cheapness,' not for survival or some other equally strong interest.
