Abstract

Counterexamples to knowledge-action links are cases in which, intuitively, you know some proposition but aren’t rational to act accordingly. For example, it’s hard to plausibly deny knowledge of obvious truths like 2 > 1. But when given a choice between betting on 2 > 1 or disjunctions of obvious truths, it seems only rational to bet on the disjunctions, contrary to what knowledge-action links predict. I defend knowledge-action links against this charge. Appearances to the contrary, you should be indifferent between the options in such cases. Any slight increase in value of betting on the initial obvious truth should make you bet on that proposition rather than on the disjunction. But if any slight increase in the value of an option should make you bet on that option, then you never should have bet on the other option. Therefore, as knowledge-action links predict, you should be indifferent between the various options in these cases.
