 There are various complications involved in interpreting this rule (for instance, it refers to “drawing a conclusion”, which is an all-or-nothing judgment, as well as credences). But notice that, unlike Rational Reflection, the Calibration Rule makes no reference to rationality. (It does specify that the conclusion is drawn on the basis of some evidence, but as White points out in his discussion of the rule, the evidence plays no part in determining what we should believe.)
