The formal modal formula is B(Bp -> p) -> Bp.
It looks also like wishful thinking. If you succeed in convincing a
Löbian entity (whose beliefs are close for the Löb rule, or having
Löb's theorem for its bewesibar predicate) that if she ever believes
that some medication will work, then it work, then she will believe
the medication works!
But that's equivocating on "B". In the formula it means beweisbar=prove
not "believes". I think that is obfuscation.
