I should clarify - rather than ‘backfire,’ exaggeration in Majority Judgment either does nothing or carries a social cost. Here’s why:
- If a minority exaggerates votes, the median stays unchanged.
- If everyone exaggerates equally, the same winner emerges, but an artificial high tide of exaggerated grades obscures the real depth of public opinion. This defeats one of MJ’s key strengths: the ability to show when all candidates are viewed poorly and therefore create pressure for better options.
Regarding partisan concerns: Yes, MJ is vulnerable if partisan blocks coordinate to exaggerate grades. However, MJ offers two meaningful advantages in a two-party system:
- Voters can grade third-party candidates highly without ‘wasting’ their vote, as they can still support their party’s candidate.
- Once again, poor candidates from both parties could receive revealing low grades, encouraging better alternatives.
Of course, you were hinting at the fact that MJ’s success in a two-party system depends on fostering a political culture where candid evaluation flows more freely than partisan loyalty. But this is the current that all voting systems must swim against; partisan pressure can steer dolphins’ fins at the polling station regardless of the method used.
Sorry if you know this game, but I’ve met plenty of people who haven’t and I’ve never seen it mentioned online until I searched for it today: Contact!
