Abstract
<jats:p> The two main criticisms by approval voting (AV) supporters have been that majority judgment (MJ) is not “Condorcet” and that it admits the no-show paradox. That MJ is not Condorcet consistent is a good property shared with AV: the domination paradox shows that majority rule may well err in an election between two. Whereas the no-show paradox is in theory possible with MJ, it is as a practical matter impossible. Moreover, it is proven that MJ with three grades does not admit the no-show paradox. In contrast, AV suffers from serious drawbacks. With AV, voters cannot express their opinions adequately; experiments show that Approve is not the opposite of Disapprove and that AV does not admit the no-show paradox—it admits the very closely allied no-show syndrome. Two grades are simply too few! The debate must concern three or more grades. </jats:p>
