I think you could say correlation and causation are correlated, but I don't think it's fair to repurpose the word "equal" to mean something it doesn't.
If two things have a causative connection they ALWAYS have a correlation as well.
If two things have a correlative connection they don't always have a causative connection as well.
I never repurposed the word equal. But to say they are not equal is highly, highly inaccurate.
Correlation does not imply causation but causation DOES imply correlation. Applying the word not equal to this is not accurate at ALL.
Seems like pedant-ism but it's not. Trust me. Correlation is evidence for causation. But people always throw this term around as if finding a correlation between two things is utterly useless in determining causation.
It's like me presenting a witness who saw a murder occur. Technically speaking, the witness is evidence for murder, not proof of murder. This fact is obvious to everyone. It's completely useless to say something obvious along the lines of:
TESTIMONY != PROOF
The testimony is strong evidence for murder, as correlation is strong evidence for causation.
Seriously, someone just posts one line CORRELATION != CAUSATION and everyone just gathers around this misnomer as if it renders the correlation utterly useless and pointless. No. The correlation is a TESTIMONY to a murder. It is powerful evidence. Do not dismiss it based off some stupid statistical catch phrase.
