Tom Hartsfield at Real Clear Science has a nice short piece that explains why your mind isn’t involved (at least not directly) in what happens in quantum mechanics: Does the Mind Affect Quantum Mechanics? | RealClearScience.
Every measurement that you can name boils down to an interaction. You poke the quantum system with something (light, a tiny probe, a thermometer, a calorimeter, a laser, etc.) and that something interacts with it. Your probe is altered by the interaction, and you look at this alteration to understand your measurement. Light is deflected, new light comes out, the thermometer level rises, your probe is pushed back.
A quantum system is in a completely uncertain state only when isolated — i.e., interacting with nothing else. When an outside object comes into its space, the intruder interferes with the quantum system and forces it to collapse from uncertainty down to a definite spot. You can mathematically treat the impinging second system as classical or quantum in nature. Either way, the overlap of the measuring device or the spread out areas of its constituent quantum systems force the quantum system you measure to resolve.
There was early speculation in the physics community about a conscious observer having an effect on the measurement, but physicists have long since moved past it. However, that early speculation has been enough for a lot of spiritualists to take quantum mechanics as indication for all kinds of pet ideas.
Quantum mechanics is weird. It is freaky weird. That’s why there are so many interpretations about what exactly is happening. Whichever interpretation is right (assuming any of them are), the implications for our understanding of reality are profound. Every interpretation involves giving up at least one cherished notion of how we commonly think reality works.
But we can be pretty sure that the mind is not the deciding factor. One good example of this is all the effort that goes into insuring that qubits, the logical components of quantum computing, are isolated from the environment in order to prevent premature decoherence or wave function collapse. No conscious person is looking inside these components when they prematurely collapse.
Whatever is happening during the measurement, it’s the interaction with the environment that causes it. The closest thing that can be said about conscious minds being involved is that they are part of that environment.
