Mistaken causation

Colonel: We implemented the troop surge in Iraq. Shortly afterwards the violence decreased. Obviously, the surge worked. Lieutenant: Where is the proof it was the surge? Couldn't the final separation of violent factions into separate enclaves within Baghdad be the real reason. The people who hate each other are for the first time far apart from each other. That process finished up at about the same time as the surge. Colonel: All I know is we increased troops by 20,000, and the violence went down. It don't take a rocket scientist to figure out what caused what. What is it with you young officers? You think too much. Surge, then less violence. What else do you need to know? Lieutenant: Oh maybe why and how the surge is decreasing violence. Maybe like some evidence and facts.

Cheerleader: We've always done it. It's a tradition. Football Player: They just wait for us to show up, and then there's a big fight. Every year. Seems like a stupid tradition. Cheerleader: It's the way it was when my parents went to this High School. Football Player: Sounds like we need new traditions.
