Oh yes I got my definition of correlation slightly wrong. Correlation doesn’t necessarily mean that two things have the same cause but they do relate in some way either by having a common cause or by occuring in the same system. They definitely have more in common than happening just at the same time or right after each other like a coincidence.

I didn’t claim that correlation equals causation and I hope you didn’t get the impression because this would be oviously wrong.

Edit: I stand corrected and today I learned that “correlation” means that two things have a statistical relation without any causal relation implied. There can be a causal relation but it’s not necessary. The key takeaway for me is that correlation describes a statistical relationship.

Do you have an example? I’m pretty sure correlation cannot be caused by coincidence.

Coincidence is describing two things happening at the same time but with separate causes. Correlation is describing two things having a common cause.

Not exactly. What you’re looking for is coincidence.

I’m probably as new as you are but as far as I understand the ALL page correctly, it doesn’t necessarily show ALL existing posts on all nodes in all communities but “only” all posts in communities that federate to your node.

Since different nodes have different federation policies, you will see a slightly (?) different ALL page.

Maybe someone who has more experience can elaborate on this topic.
