The hypothesis that a conscious observer collapses the wave function has been discarded, right? The real reason is that the particle you use to measure the other disrupts the wave function, forcing it to choose an eigenvalue. So since we are able to remove the conscious observer as the cause, I'm confused how to interpret everyday reality. Wouldn't almost all particles be forced to constantly choose an eigenvalue because they are so closely interacting with everything else (like my foot and the floor)? This would lead me to speculate that only the rare particle that is isolated enough, like in the vacuum of space or in the laboratory, would be in a superposition of eigenvalues and the majority of matter around us is constantly at a defined eigenvalue due to the wave function always collapsing.
