Imagine looking out the window and seeing stuff that is happening outside. If the window gets foggy, you don't experience everything that's happening outside the window. That doesn't disprove that you are observing stuff outside the window.

On the other hand, having "uncaused effects" has been found in quantum mechanics, but it's too much of a leap to suppose that your consciousness controls your body through quantum mechanical probability. Although there's something eerie about the waveform collapse having to do with conscious observers.

Fortunately, it doesn't. Any measurement of a system constitutes an "observer", conscious or not.

So does the wavefunction collapse when Schrodinger's cat observes it? Or when the detector observes the radioactivity?

Yes - from the subjective perspective of Schrodinger's cat. Yes - from the subjective perspective of the detector. From the outside we observe the cat's state becoming entangled with that of the radioactive sample, but from the cat's perspective it made the observation, collapsed the state, and either died or didn't.

It's exactly the same for us, making the observation - from our perspective we observed one result or the other, collapsing the wavefunction. But to an outside observer we entangled our own state with that of the cat and the sample, and we're in a superposition of (observed cat dead, observed cat alive) - and will be until they observe us, at which point our wavefunction will collapse to one or the other. And so on.
