I believe that the meaning of what was originally stated was that correlation suggests a possibility, not that it implies or infers causation. Certainly we all know about the false reasoning that allows us to believe in causation due to correlation, when the relationship is simply coincidental. BTW, for your story about the cat: In a statistical sense, the head predicts the tail. Quite a difference from the head causes the tail. David McNeely
