If you were to do a study with openable jars (or at least ones that

to show that one technique worked more often than another. Just
observing how people attempt to open an unopenable jar doesn't
really prove anything other than the fact that different people use
different approaches.

Except that certain ways of doing things are demonstrably stronger
than others.

I'm not really arguing with that but your test won't prove that, will it?
If the jar can't be opened, how do you prove that one way is better than
another?
