Voters dislike disproportionality in electoral systems – even when it benefits the party they support

Taking advantage of a uniquely designed survey experiment, Carolina Plescia, André Blais and John Högström investigate the effect of proportionality on voter support for voting rules in four countries, namely Austria, the UK, Ireland and Sweden. They find that voters for both small and large parties dislike disproportionality in electoral systems, with little cross-country variation.
