What makes a good example
A useful quadratic voting example has clear alternatives, people with unequal stakes, and a reason to measure intensity rather than only first-choice support.
Nicolas examples focus on decisions where the group wants a record of signed vote intensity, quadratic costs, delegation, and outcome probabilities.
How to read the scenarios
The examples do not claim that every group needs quadratic voting. They show decision patterns where the squared-cost rule reveals information a simple poll would hide.
Use them to decide whether your own decision needs an intensity-aware signal or a simpler voting method.
