    I think the question is, what is inference?

    If inference is belief, it is likely to be all wrong
    anyhow; the current theories are just wrong, and the
    null hypotheses, at least as tested, are false.

    So I consider the sole problem as what action should be
    taken, and if more than one, they should be essentially
    equivalent. This is what "fuzzy inference" does not
    address.
