In Paranoia I never avoid treason (which is impossible anyway).
In Fate I never refuse a Compel.
In 7th Sea 2e I never buy off Consequences (unless it's damage or instant death).
Why should I?
Because I've yet to encounter a case where blocking these would be a net win and lead to a better play experience, and if a Compel or Consequence isn't something that would lead to a better play experience, then why offer it in the first place?
On the other hand many players see any loss of control as 'failure', so they tend to block these offers regardless of incentive. In these cases I understand why these choices matter. But once you understand what the system actually rewards and buy into it, you can reliably play to it so well you effectively render it irrelevant.
This leads to an interesting hypothesis: A system which encourages behavior you naturally engage in actually gets in the way of it, and a system which encourages behavior counter to what you naturally engage in causes dissonance but not a change in behavior. And I'm just staring at this, wondering how true it is, and what to do about it.
