This is how I view debugging, aligning my mental model with how the system actually works. Assumptions are bugs in the mental model. The problem is conflating what is knowledge with what is an assumption.

I've once heard from an RTS game caster (IIRC it was Day9 about Starcraft) "Assuming... Is killing you".

When playing Captain Obvious (i.e. the human rubber duck) with other devs, every time they state something to be true my response is, "prove it!" It's amazing how quickly you find bugs when somebody else is making you question your assumptions.
