I am aware that the observer effect as is being described here is the use of instruments, because by the act of measuring or detecting you are
affecting the the experiment. However, it is also true of regular observation, in the act of observing you are collapsing the wavefunction of matter.
This is what Schrodinger's cat-in-the-box thought experiment demonstrates and later Bell's experiment corroborated.
I know somebody who works as a quantum physicist and they have told me that the observer does indeed collapse reality. In the doube slit experiment,
the particle collapses into a wave just
before it passes through. If it observed on the other side, it turns back into a particle.
Observation is crucial for there being any reality at all. How you access reality is how it will appear to you. The form of something is not what it
really is, because that form will change with your modes of access. It is easy to assume that the chair is an actual real object. However, this is
false because that chair would only assume a form based on the observer. It would appear different to a human observer, an animal observer, and via an
instrument. In other words reality is a interaction between the observer and the field of observation. There is no reality without an observer.
