IME the role of logic in decision-making has been greatly overemphasized. People need to first be convinced in an emotional/intuitive way, then given logical arguments to support what they are experiencing.
The idea that a person -- anyone, not just "dumb people" -- think first about a matter rationally and then act in a matter consistent with logic, is failing to address a huge component of human behavior: people only behave in their rational best interests if/when they are not emotionally invested in the outcome.
I'd be writing from the Moon right now if obvious-to-state were the same thing as obvious-to-achieve. Even if we accept your unwarranted assumption that strict rationality is unilaterally superior to experiential and intuitive modes of being, which is not at all a given: how do you propose we induce a widespread emotional investment in living life like a Vulcan, something that runs counter to the instincts of many/most people?
Edit: sorry that came out quite jerk-like. Point is, why is rational always better than intuitive, and how could anyone hope to create such a massive emotional investment in an intellectual concept.
