@Kat919 - Oh, those make me so mad! So many articles just don't make it clear that one thing doesn't necessarily cause another just because you find them together.
Another post hoc fallacy example is a recent study showing that kids who spent a lot of time on Facebook and other social media are more likely to drink and engaged in other risky behaviors. The reporting made it sound like Facebook *causes* drinking.
How about this: kids with a lot of friends, or who are very concerned with their public image, are more likely to drink, and also more likely to go on Facebook?
Obviously, the study doesn't show that Facebook use *doesn't* cause drinking. But it's important to remember the correlation is not causation.
