I think part of the issue is people fail to carefully distinguish between physics and interpretations. Interpretations are actually more philosophy than physics. The physics can be experimentally demonstrated to be correct. The interpretations are essentially untestable.

A lot of people make statements which assume the truth of some particular interpretation of quantum physics, without realising that it is just one of many. Many advocates of "quantum mysticism" are adopting the von Neumann-Wigner interpretation ("consciousness causes collapse"), and they often misidentify that as "Copenhagen" even though it isn't. But on the other hand, many of their detractors are committing a similar error, and presuming Copenhagen or many worlds as if it was the actual physics as opposed to just one of many competing philosophical interpretations of it.

Can you explain how "consciousness causes collapse" differs from the Copenhagen interpretation? I'm one of those people who think of it as meaning that, except from the other side: I feel like "consciousness causes collapse" is wrong and count that against the Copenhagen interpretation. But if Copenhagen doesn't necessarily presuppose that then maybe I'm going wrong.

The Copenhagen interpretation, also known as "shut up and calculate", asserts only that the mathematics of quantum mechanics are accurate, that is, predictive of observation.

Assigning metaphysical implications is declared out of bounds. It's a useful compromise.

Ah, OK. So in a sense it's barely an interpretation at all.
