Voters slide every option between strongly disapprove and strongly approve. The option with the most net support wins.

For example, 12 books for a year of book club. The options with the most overall support win, in order.

How influence is spent
Influence per voter

100 is a good start: one option pushed all the way, or several pushed part of the way.

About the maths

The mathematically grounded way to make your opinions count.

Option A Option B 71, 71 100, 0
  1. Your ballot is a vector. Each option is a direction, and each slider is how far your ballot points that way.
  2. Influence limits the vector's length. With quadratic cost, every score squared and added up can't exceed 100 × your influence: the Pythagorean theorem, in as many directions as there are options. You choose where your arrow points; your influence sets how long it can be.
  3. Results add the vectors. Everyone's scores are summed, so the result is the group's combined vector: where the room points, and how strongly.

With two options and 100 influence, every ballot that spends it all ends on the circle: one option pushed all the way, or about 71 on each. Linear cost limits the "city-block" length instead (how far each slider moves, added up).

Quadratic cost is quadratic voting, developed by economists E. Glen Weyl and Steven P. Lalley. "Halfway costs 25, all the way costs 100" is the same maths in friendlier units.

Anything other than Secret requires names, and voters are told before they vote. This can't be changed after the decision is created.
