A great way is to encourage them to question the rules that they have to follow, including your own.

That's something they already do, and most enjoy doing. We just need to guide them to question the rules in a coherent manner.

Besides critical thinking and argumentation, by letting them question your own rule, the meta skill you're demonstrating here is intellectual humility, IMO the most prized quality of a great thinker.
