As noted in the preceeding article, BRV requires the voter to mark a single candidate as either Approve or Disapprove, but as with BAV, the BRV-voter is not responsible for selecting the candidate. Still, so long as there are a sufficient number of voters, the election results (in terms of who wins and who loses) are, to a high degree of confidence, the same with BRV as with BAV. The only serious difference might be with voter satisfaction.
But many people seem to enjoy gambling and the excitement of not knowing how the toss of dice or the spin of a wheel will end. Perhaps the promised surprise of learning which candidate a voter will be asked about will actually make elections more interesting and actually drive more voters to the polls.
