Oh yeah, don't get me wrong, consciousness is probably the least explainable thing whose existence I'm aware of. But the gap in our knowledge doesn't automatically mean it's something that exists outside of the rest of the laws of physics. To scientifically show something is true, you need to disprove the other possible explanations (which is impossible because there's always other possible explanations).

The double slit experiment does not prove consciousness is a special case in how the laws of physics works. There's actually two results in it: how the slits interact with the particle/wave and how the particle/wave interacts with the photo-sensitive plate. We always observe the plate but only sometimes try to observe which slit(s) it travels through. The variations I mentioned above were ways to separate the conscious observer running the experiment from the non-conscious "ovserver" which is the sensor.

If it's happening because of the consciousness being involved, then the sensor measuring but never recording shouldn't affect the outcome and you should get a wave pattern. Similar for it it is possible to view the results but the observer decides not to, no matter the outcome. But then once they discard that conviction, then either it pops over to the particle result (if conscious observation means it has to act like a particle) or stays as a wave pattern but now you've been able to do what has never been done and measure which slits it traveled through and when to make that pattern. These variations are so obvious that they had to have been done, and since I'm not aware of conscious observation being proven to affect the outcome (as opposed to all observations require interaction, which can affect the outcome, no consciousness required), I assume they just got the particle result as long as the sensor was doing anything at all.

That one possibility is powerful, that deciding to do something can change how something behaves. It could be used for FTL communication and arbitrary prediction of the future, which makes me inclined to believe that it doesn't work that way.

All that said, I do agree that it could be the case that consciousness is as important to the laws of physics as all the other things but confounds every attempt to measure it. I'd love to believe that, even, and a part of me does. But without anything definitive, the other part of me will hold on to the thought that it's just wishful thinking.

That's also part of the reason I pushed back. I'd love for someone to "well, actually" and prove something about consciousness or even just show me a new argument, so I'll bring up the parts that make me skeptical or explain the way I see it. I want to believe.
