I'm not sure that my goal is to get people to believe as accurately as possible so much as it is to get other people to do the right thing. That is to say, my goal is persuasion.
Generally speaking, I also try to encourage people to believe as accurately as possible. However, as a practical matter convincing people to do that doesn't scale.
I think you are saying tbe same thing. “Do the right thing” means “their beliefs are accurate with regard to what is the best action to take.” Of course, it assumes you are starting out with the “right” action, which is why a much better goal is “ensure everyone believes as accurately as possible.” That way you aren’t just persuading them (and in fact you aren’t even looking at it as an issue of persuading them), rather you are taking the view of how best to ensure both parties are optimally persuaded by the facts.
A goal to persuade without a goal to induce accurate beliefs is just manipulation.
