Alcohol-Branded Merchandise Boosts Teen Drinking
Can't you can take the same 'research' and say: Teen Drinking Boosts Alchohol-Branded Merchandise Sales???
It makes more sense to me that kids who are already drinking would buy a Cuervo t-shirt than it does that same t-shirt propelling impressionable children over the abyss of alchoholism. Once again it's time to demonize inanimate objects because the 'researchers' lack the insight and strength to see the problem where it lies!
The goal is to actually demonstrate causality, not correlation. In the absence of being able to demonstrate causality, a (good) researcher can only state that there appears to be correlation.
Not as forceful a conclusion, but more acurate.
