That’s a lot of assumptions that I can’t agree are inherently true. Forcing people to participate might not make them think at all beyond fulfilling the duty and not paying a fine, and random votes might not balance out the charismatic leaders at all - if anything the charismatic populist leaders that focus on good PR over substance will probably gather up more of these uneducated “just circle something” voters than the others. It is where/why marketing and commercials work so well in the first place and I’d rather not give even more power to this type of brainwashing, it is a popularity contest enough as it is.
If anything, I’d make it so in order for people’s votes to count they need to show at least a very basic understanding of what they are voting for and what are the implications of it.
Not necessarily true, I think most of those votes would go to the most popular populist candidate or the one with a better PR team, it wouldn’t be truly random distribution.
