The Experiment Paradox, Okay, So You Want to Test a Physical System?

We call it the experiment paradox, and so the paradox for speaking is the following. So suppose you have a some physical system, you have a model of it, say it should behave this way and that way,. You need to make an experiment on your system and compare the outcomes with the predictions of your theory  and see if they matter or not. If you use anything that is pre-correlated with the system, then your experiment is not right because you don't control your input. That's what we call the Experiment Paradox.
