From that link, and agreeing with my prior research, and what I stated above:
"In physics, the observer effect is the disturbance of an observed system by the act of observation.[1][2] This is often the result of utilizing instruments that, by necessity, alter the state of what they measure in some manner."
There's no woo woo, magical change we effect by perceiving. We use instruments, such as bouncing particles off of other particles, in the process of observation, and these, obviously, affect our targets of observation.
Edit: regarding God, I also stated this above:
"While I completely agree we have free will, that doesn't mean our actions can't be predictable by those possessing fuller understanding of us and our environment."
Nothing better understanding of the subject doesn't make entirely predictable is portended by these presents.
