'Expectation bias' is not an explanation of anything. It does not and
cannot 'explain' specific aural phenomena, any more than 'phlogiston'
explains combustion. No-one discussing 'expectation bias' in scientific
literature uses it that way. 'Expectation bias' affects the
interpretations of observations, not the observations themselves.
