I just saw the movie "Don't look up" from 2021 in which a divided US cannot stop a comet hitting the Earth and destroying life
In nature dumb and weak animals are eaten by predators and herd is improving.
But the humanity,large groups in general depend on taking colective decisions.
For example a country cannot go 30% to a war, either will go 100% either will lose.
And you stop stupid people to steer the decision in wrong direction?
Who are stupid people? All of us. When we act in a domain that we don't have experience, knowledge or talent.
Jan Hus the Czech religious reformer when he faced inquisition in Rome, he saw an old woman carrying a bundle of wood for his pyre, waiting for the end of his trial, and he said: "Sancta simplicity's" holy stupidity.
An illiterate woman understood what he as a scholar who read latin and Greek didn't. That he was already sentenced.
Another case: after Henry viii separated from church of Rome and created Anglican church, it was a riot of peasants lead by learned men like lawyers and noble men.
Henry VIII beeing cornered, demanded that rebels to send some envoys to negotiate. The leaders offered to meet the king, but they discounted the advice of peasants to demand hostages as guarantee of their safe returns.
The rebel leaders were cought , executed and revelion routed.
So how we separate Stupids so they don't affect the community?
How we can separate people so only they pay for their mistakes and not others ?
