    The argument that is accessible to anyone is Just Be Rational, Or The
    Unknown Variables Will Eat You. We know a couple of what are, from the
    majority perspective, unknown unknowns, and we can confirm that the
    presence of those unknown unknowns does in fact operate to reinforce the
    rule and create nonobvious incentives for rationality. But on new cases,
    the argument is the same for us as for anyone else. We don't know all the
    unknown unknowns either.

    In any case, we should distinguish between the question of whether the
    right answer is Just Be Rational, and the question of how persuasive the
    right answer happens to be. People are playing the game for enormous,
    nonancestral stakes, even in their own lives, whether they realize it or
    not. How wonderful that the Just Be Rational strategy, accessible to any
    audience, returns the right answer even in the face of such tremendous
    surprises!

    The universal argument is "Just be rational or you won't even see the
    bullet that kills you." We know several specific instances of such
    bullets that are not widely known, which shows that the universal argument
    has turned out to work so far; as we accumulate additional experience and
    knowledge, it tends to show that the heuristic was correct. Speaking from
    my experience, this heuristic not only turned out to lead to the correct
    answer, in retrospect it often seems like this heuristic is the only
    possible way for a human to arrive at the correct answer without
    anachronistic advance knowledge.

    If you are worried about finding disappointingly weak *arguments* for
    rationality, *arguments* as opposed to *rational support*, then that is
    quite a different question from the one I thought you were asking. I'm
    worried that quantum mechanics also has disappointingly weak arguments
    relative to a layman audience; for example, it lacks the dramatic appeal
    and intuitive animism of elephants on the back of a giant turtle. But
    that is a question of needing to write lengthy explanations, not of the
    principle itself being wrong.

    But I don't think JBR is, in fact, inaccessible. The Just Be Rational
    strategy is not only employable by anyone, it has arguments which are
    accessible to anyone - as widely available as the nutritionless package of
    fat and sugar at the grocery store, the history of scientific discovery,
    the innate drive to know the truth. The list of reasons I originally
    offered were simply put; only the replies to your complex counterarguments
    were complex. Truthseeking is a simple and intuitive idea. The idea that
    we execute adaptive self-deception is a complex counterargument. A box of
    Little Debbie snack bars is a simple but iffy illustration of the complex
    reply to the complex counterargument; the Singularity is a more valid
    illustration, but less accessible.
