Does information about the consequences of proposals to change the Storting electoral system influence voters’ attitudes towards it? Is the willingness to change it greater among voters who «lose» with the current electoral system? These questions are illuminated based on empirical data fromthree survey experiments on 1) proportionality (across political parties), 2) geographical representation (stronger representation of the populous election districts), and 3) increased preference voting. The results show that information about the consequences of the proposals is very important for the respondents’ attitudes. In particular, this concerns the issue of increased party proportionality, in which respondents who received information that the proposal may weaken the representation of larger parties and complicate the formation of governments are particularly negative. The responses to the question of increased party proportionality are also contingent on whether the respondents themselves voted for one of the smaller parties in the 2017 Storting election. Voters supporting small parties are especially supportive of changing the electoral system in a more proportional direction.We also find that there is limited support for the proposal to allocate the parliamentary representatives on the electoral districts according to the number of residents living in the districts, and this support is reduced further when respondents are informed that it will strengthen the representation of the more populous parts of the country. Furthermore, a majority of voters supports the introduction of increased preference voting, and this support increases somewhat when respondents are informed that it will strengthen voters influence over who is selected to the Storting.
