I don’t pay a lot of attention to a certain well known quack who argues that atoms are conscious. However, I ran into a philosopher who mistakenly believed the nonsense about consciousness being needed to cause a wave function to collapse.
Physicists have mathematical models describing what happens at the quantum level which make very good predictions, but these are models, and not reality. The wave function that is a solution to the Schrödinger equation describes the behaviour of particles at the quantum level, but what happens when we go to try and measure a particle? We have an interaction between the wave function that describes the particle, and the wave function that describes the particles of the measuring instrument. Why yes the observer affects the observation, but a brick wall would do just as well.
