I’d like to see that too, but the way to get citizens with the qualities you desire is, imo, infrastructural and not best done via a filter. Currently, we churn people out of high schools half literate then feed them profit-driven slop on their tvs and phones, then we expect them to somehow make cogent political decisions. I don’t know this for a fact, but my intuition is that if you improved the relevant infrastructure you’d produce a majority population capable of pretty solid political thought, where your solutions more resemble band-aids with undemocratic side-effects. It would be harmless if you did it perfectly, but any real-world anti-voter filter or social pressure would inevitably be used for undesirable, irrational ends.
