You get different results based on which part of the experiment you’re observing.
For example: double slit experiment.
We always observe the end result of the experiment (the distribution of the particles on the final surface.
But if you also have some apparatus detecting (observing) through which slit the particles go through, the result changes.
Also you seem to think “observing” is related to vision in some way. It’s not. Observation is just a specific category of quantum interactions.
