The average person in the US reads at below a high school level.

How do you explain to someone who doesn't understand high school level writing, let alone math, that "No, you can't just say Pi is 4, it doesn't work like that" in a way that they will agree in the end, rather than just calling you an elitist shithead who is patronizing them?

I think that could depend on if we are fine with having an administrative state. I.e. can regular people have simple laws and then have experts work out the highly nuanced details?
