If the statistics show that creative people are correlated with longer life, but that longer life is only correlated with creativity if factors X, Y, Z are also present (but not necessarily just X, Y, Z without creativity), then it would be correct to say "creativity predicts longer life" but not "longer life predicts creativity"; while not implying any causation.

Also it could be that some long living people are creative and all creative people are long living; while creative still not being a cause of the longer life. (let's say all creative people eat peanut butter sandwiches, and it was infact the peanut butter that caused a longer life.)

"The weatherman predicts the weather". Are you saying in this sentence, causation is implicitly referenced?
