Voters have an incentive to be ignorant. When
acquiring information about candidates, the benefits of
the information may be less than the costs of its
acquisition, which means it is rational to be ignorant.

No, rational ignorance and irrationality are not the

interest. To be rationally ignorant implies that you are
acting rationally by being uninformed. In this case, the
costs of being informed exceed the benefits of
becoming informed.
