Actually a paradox is something that appears to be a contradiction. It comes from the greek for "contrary to expectation". So often a paradox is about wrong expectations and not a contradiction in of it self.

right. but saying there aren't paradoxes in quantum mechanics isn't helpful and is probably just wrong. quantum mechanics isn't a physical thing and isn't reality. it is a model. of course it can have paradoxes, and does.

A model with a paradox is usually considered a flawed model, as it a logical contradiction, and from a logical contradiction anything can be proven.

"Proof by contradiction" is a proof that the opposite is true, and is constructed so that if the thing you try to disprove would be true, you could create a paradox/contradiction.

> A model with a paradox is usually considered a flawed model

that is the critique at hand, is it not? my understanding of the paradoxes in quantum mechanics stem from things, like measurement, being unspecified or at least being specified or interpreted without consensus.
