Correlation is not causation, and correlation does not logically imply causation, but correlation is evidence of causation [1] which in a looser English context could be taken as a sort of implication. Many correlations aren't worth digging into, but others are, so you can't just dismiss all of them outright with "correlation doesn't imply causation."
