Simpler question: Is it possible to learn to cheat at coin flips?

If you can cheat at an actual "fair" coin flip (not just making it wobble or using a rigged coin), then it's at least possible for your brain to build a correlation between desired and actual outcomes. Given that this is a common decision making tool, I'd expect positive and negative reinforcement to have resulted in at least mild entanglement in that case; the two aren't completely independent.

I've learned to bias "fair" dice rolls, so I'd assume it's possible to develop similar muscle reflexes with coins. It was over a decade ago, so I don't remember how well I did with coins, alas :)

tl;dr: If you can cheat, it's probably entangled. If you can't cheat, it can't be entangled!

I don't think the entanglement you mean is the quantum one except in a sense that "everything is quantum".

I can't imagine that something I have conscious control over could be quantum random, since it's not even regular random. If I'm mistaken on that, please let me know :)

See previous comment on Jaynes. He details how to control the outcome of the toss by how you throw it. Whether that amounts to cheating depends on the use you put this mighty power.

There are other papers online as well. Most will refer back to Jaynes, so "jaynes coin flipping" yields some hits.

So, if we've established that you can control the outcome, then it seems obvious that the event isn't going to be properly random :)

I guess I didn't italicize properly. I was just pointing people to Jaynes description of how to bias the coin toss, since I thought it might be of interest.
