Craven, I may have to think about that some more, but I think you're right: this is an example of a
cum hoc ergo propter hoc fallacy:
McGentrix wrote:Since the war began, there have ZERO terrorist attacks on American soil. I woould say that woould be an example of us "winning the war on terror".
To give another example:
Homer: Not a bear in sight. The Bear Patrol must be working like a charm.
Lisa: That's specious reasoning, Dad.
Homer: Thank you, dear.
Lisa: By your logic I could claim that this rock keeps tigers away.
Homer: Oh, how does it work?
Lisa: It doesn't work.
Homer: Uh-huh.
Lisa: It's just a stupid rock.
Homer: Uh-huh.
Lisa: But I don't see any tigers around, do you?
[Homer thinks of this, then pulls out some money]
Homer: Lisa, I want to buy your rock.
In the above example, substitute "Dubya" for "Homer," "terrorists" for "bears," "homeland security" for "bear patrol," and "anyone with an ounce of common sense" for "Lisa."
