Political Weirdtopia: Citizens decide it is unfair for a democracy to count only the raw number of people who support a position without considering the intensity with which they believe it. Of course, one can't simply ask people to self-report the intensity with which they believe a position on their ballot, so stronger measures are required. Voting machines are redesigned to force voters to pull down a lever for each issue/candidate. The lever delivers a small electric shock, increasing in intensity each second the voter holds it down. The number of votes a person gets for a particular issue or candidate is a function of how long they keep holding down the lever.

In (choose one: more/less) enlightened sects of this society, the electric shock is capped at a certain level to avoid potential fatalities among overzealous voters. But in the (choose one: more/less) enlightened sects, voters can keep pulling down on the lever as long as they can stand the pain and their heart keeps working. Citizens consider this a convenient and entirely voluntary way to purge fanaticism from the gene pool.

The society lasts for several centuries before being taken over by a tiny cabal of people with Congenital Insensitivity to Pain Disorder.
