Perhaps that extremely simple systems, that no one would consider conscious, can also "cause collapse"? It doesn't take much: just entangle the superposed state with another particle - then when you measure, canceling can't occur and you perceive a randomly collapsed wavefunction. The important thing is the entangling, not the fact that you're conscious: measuring a superposed state (i.e. entangling your mind with it) will do the trick, but it's entirely unnecessary.
I used to believe the consciousness-causes-collapse idea, and it was quite a relief when I realized it doesn't work like that.
Some of the consciousness causes collapse people would claim that you intended to cause that entanglement. (If you are thinking this sounds like an attempt to make their claims not falsifiable, I'd be inclined to agree.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
If continuing the discussion becomes impractical, that means you win at open threads; a celebratory top-level post on the topic is traditional.
