Are depressed people more realistic?

Firstly, Cracked, while an excellent entertainment website, is obscenely poorly-cited. That being said, whether Roosevelt knew Pearl Harbor was going to happen (I actually believe he did not have specific knowledge of any attack) is irrelevant as to whether the war itself was predictable for the world or even just for the U.S. In fact, I would call that as shitty an example as could be, given that the war had already started by the time the incident you cite occurred. That means, you are saying they couldn't "predict" the war by the time it had been raging for years.
