Wouldnt the president have reviewed more than one report before deciding to have soldiers invade Iraq? Did he ever hear doubt from anyone at all? Did he ever ask for a second opinion? Geee. I guess that he went with the first report that he had and, coincidentally, it stated no doubt. That seems to be rather reckless to me.
Based on my experience with watching predictive weather reports and the rate at which they are wrong, if I were planning an important outdoors event, I would ask for a second opinion just to be more confident. If you were going to experience a major, expensive, life-threatening surgical operation based on your first doctors opinion, wouldnt you look for a second or even a third opinion before deciding to do under the knife? I sure would.
By the way, with respect to the weather report, just because you do not see a newscast say that there will be no rain, does not mean that there exists no doubt among some meteorologists that there will be rain. It just means that you decided to go with the first weather report that you saw. You might have no doubt but you did not check out opinions from other weathermen. That does not mean that, nowhere in the world is there doubt. Do weathermen ever disagree on what the weather is going to do? I think so.
