QM link:
“Randomness comes in two qualitatively different forms. Apparent randomness can result both from ignorance or lack of control of degrees of freedom in the system. In contrast, intrinsic randomness should not be ascribable to any such cause. While classical systems only possess the first kind of randomness, quantum systems are believed to exhibit some intrinsic randomness. In general, any observed random process includes both forms of randomness. In this work, we provide quantum processes in which all the observed randomness is fully intrinsic. These results are derived under minimal assumptions: the validity of the no-signalling principle and an arbitrary (but not absolute) lack of freedom of choice. The observed randomness tends to a perfect random bit when increasing the number of parties, thus defining an explicit process attaining full randomness amplification.”[/quote]
Hence the definitions scientific randomness vs. philosophical randomness are different. As described above this statement “we provide quantum processes in which all the observed randomness is fully intrinsic” is does not fit the definition of an uncaused event philosophically. Having an intrinsic random behavior is caused by virtue of the fact that said observed randomness is an intrinsic property of that which is observed. That means said particle is following the pattern of a property in which it posses.
For instance, firing a photon at a double slit window, you don’t know which slit it is going to go through, but it’s going to go through a slit and hit the media behind it. That alone ‘appears’ random, but there are some problems with that. A photon must be put into motion, it always goes through a slit and if you fire enough of them, they always create an interference pattern. It’s ‘random’ with constraints. A truly random act cannot be constrained, cannot follow any kind of a pattern and can never be predicted.
We know a photon is going to go through one of two slits, we know that enough photons will go through both slits and create an interference pattern.
That’s the problem with using quantum mechanics. We don’t know why a photon behaves like it does, but it does behave in a mostly predictable way. The only thing we cannot predict is which slit it’s going to go through. It doesn’t do it for no reason at all. As the post above said, it’s an intrinsic property, and if it’s intrinsic, it’s caused.
Randomness by philosophical standards this does not fit. On the whole it’s a predictable event guided by internal or external principles. And it’s not unreasonable to question why it’s doing what it’s doing. Philosophically, randomness is something that happens for no reason. Not that a cause that has yet to be identified or not well understood, it has literally no reason for it’s existence. There is a reason particles flip their polarity, or photons go through one slit vs another. It may be intrinsic or external, but it is not from nothing-> something.
Look at the forest and there is a predictable pattern that is repeatable. Look at the tree and you see a seemingly random event. But the event is not random, just not understood and there are as many theories as photons in an interference pattern as to why.
