Thanos test: how you would choose 50% of the world to kill?

Capitalism: bottom 50%
Communism: top 50%
Libertarianism: all-against-all. 50% left standing wins.
Anarchism: random 50%
Liberalism: debate till nature does the dirty work
Conservatism: 50% who look least like you

Progressivism has the best trick. Do futile things and reproach people who indulge in the Thanos thought experiment while waiting for nature to do the dirty work. Then reproach them for letting it happen.

Authoritarianism: Suppress information that the Thanos test is approaching, secure your 1% cronies on a space rocket. Let the rest be libertarian.

It’s a pretty good test. Most ideologies seem to map to a clear algorithm. I’m probably equal parts all of these.
