Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Such as Alain Aspect's experiment and the resulting follow-ups in another field.

I have written about this stuff on this blog. It doesn't mean I believe it has anything to do with consciousness. I have read Penrose and find him wholly unconvincing. Why am I not convinced? Paraphrasing you: I just ain't and that's all the justification you need.

Just how weird is weird?

In essence, and this is what my snappy interjection to Sven was about, it has been empirically tested (though not to the satisfaction of everyone) that the world is empirically compatible with standard quantum mechanics, but incompatible with any deterministic hidden-variable theory which has any of the following three characteristics: 1) Einsteinian locality; 2) counterfactual definiteness; 3) non-contextuality. The relevant theoretical results are "Bell's inequalities" (for local hidden variables), "Hardy's thought experiment" (for counterfactual definiteness) and the "Kochen-Specker theorem" (for non-contextuality). All three have been tested experimentally using quantum optics.

In other words: it is an experimentally verifiable fact that, if God doesn't play dice, 1) the world out there has spooky action at a distance; 2) you are not allowed to ask about the values of quantities you don't measure; 3) if you considered "what if" you had actually measured an additional quantity, the values of the ones you did measure would change.

To put it yet another way... If you think the world is made of things which have properties independent of whether you look at them or not, that the fact of looking at one thing does not affect others, or that these effects are limited in how far and how fast they can reach, well, you're experimentally provably wrong.

What is then nothing short of amazing is that the macroscopic world around us has exactly the intuitive properties I have said quantum mechanics violates.

Aspect is so 1980's. How about talking about Kochen-Specker?

Also, of course there is quantum entanglement among the electron bonds in a molecule. So what?

Economics is politics by other means
