Seeing a red hat can (i) increase my credence in the hat is red , and (ii) introduce a negative dependence between that proposition and potential undermining defeaters such as the light is red . The rigidity of Jeffrey Conditionalization makes this awkward, as rigidity preserves independence. The picture is less awkward given ‘Holistic Conditionalization’, or so it is claimed. I defend Jeffrey Conditionalization's consistency with underminable perceptual learning and its superiority to Holistic Conditionalization, arguing that the latter is merely a special case of the former, is itself rigid, and is committed to implausible accounts of perceptual confirmation and of undermining defeat.
