Does quantum mechanics allow an observer free choice of measurement?

Interactions with the invironment tend to "push" a physical system into an eigenstate of some observable. I guess you can call this a "measurement" without an observer.

This is what "decoherence" is all about.
 


The concept of observer free choice in quantum mechanics is a highly debated topic among physicists and philosophers. In classical mechanics, the outcome of a measurement is determined by the initial conditions and the laws of physics. However, in quantum mechanics, the outcome of a measurement is probabilistic and can be influenced by the act of observation.

Some argue that this suggests an element of free will or choice for the observer in choosing which measurement to make. This idea is often referred to as the "measurement problem" in quantum mechanics. However, others argue that the apparent randomness of quantum mechanics is simply due to our lack of understanding and that there is no true free choice involved.

It is important to note that the concept of free will is a philosophical and metaphysical question, and not something that can be answered definitively by science. While quantum mechanics may offer some interesting insights and perspectives on the nature of reality and our role as observers, it is ultimately up to individual interpretation and belief.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
