In quantum theory, it surprisingly was possible to test the hypothesis that things don't have a state before we measure them and then they stick to that state.

So I wouldn't rule out the possibility that we can test it for other "secrets of the universe".

This isn't true. This is exactly why we have multiple interpretations of quantum mechanics.

There are always infinite interpretations of everything.

But the "no hidden variables" theory is the most popular and well tested theory about whether things have a state before we measure it. And it postulates that they don't.

It's not tested at all. No local hidden variables is just a priori true though. It's not part of any interpretation. All of them are subject to it. This is irrelevant though because there are alternatives to local hidden variables like pilot wave theory, the so-called many words interpretation, relationalism (i.e. inherent nondeterminism) and there's no way to test between any of them.

This is what Wikipedia says about hidden variables:

    Many Bell tests have been performed and
    they have shown results incompatible
    with the constraints imposed by local
    hidden variables.

In any case, your point is moot.
