The natural solution is futarchy: Vote on values, bet on beliefs. Everybody knows that, all else being equal, they want higher GDP/cap, better GINI, a higher happiness index. Only the experts know whether tariffs will help produce this.

So, instead of having everyone vote on tariffs (or vote for a whimsical strongman who will implement tariffs), have everyone vote for the package of metrics they want to hit. Then, let experts propose policy packages to achieve these metrics, and let everyone vote on which policies will achieve the goals.

Bullshit gets heavily taxed, and the beliefs of people who actually know the likely outcomes will be what guide the nation.
