A common trope (e.g. with Brexit) about "the poor" is that they always vote for the "populist"/"authoritarian"/"evil" party. Some claim that there should some sort of an intelligence test or a wealth threshold that people must pass in order to gain suffrage.
But is it actually proven that "the poor" make the "bad" decisions when it comes to voting? Did someone crunch the numbers to find a reasonable correlation?
Let us define "bad decisions" as those made under an unconscious influence. A person votes for a decision that actually harms this very voter (or their social group). However, if the same person were provided with full, objective information about the possible outcomes of a decision, their vote would be different or just the opposite.
This also includes voting for a politician or a political party whose promises or actions lead to such decision.
