That's not a very good example of poisoning the well, and on top of that, it's a flawed analogy. "Poisoning the well" is a kind of argumentum ad hominem. It's an attempt to cast aspersion on someone's argument by presenting unfavorable information about him or her. "Don't listen to him; he's a spokesman for the tobacco lobby" is a perfect example of poisoning the well. (Not that I have any love for the tobacco lobby.) The example you gave isn't apt because the scientists who perpetrated the Piltdown Hoax, the scientists who were wrong about Ether, and so on, are not the same scientists as the scientists who subscribe to the theory of evolution today. The fallacy you're portraying in your example is more like what is known as the fallacy of Division. "Scientists generally have presented all kinds of theories that turned out to be false; therefore, these particular scientists today must also be wrong about evolution." Second, it's a flawed analogy because theories like ether and evolution can conceivably be verified by independent investigators, but there is no way for a reader of this news report to verify its accuracy. And that's exactly the problem that juliaoceania is talking about. Hell, I don't know if this story true, and maybe it is true (although I'm personally convinced that there must be more to the story than was released). But none of that is the point. The point is that I HAVE NO WAY OF KNOWING that it's true, and in fact I DO know that the armed forces in Iraq have in the past made false reports about things that were similarly unverifiable. So why on earth should anyone believe them now? quote:
ORIGINAL: pollux The reason I didn't address it is because it's a fallacy. Specifically it's a fallacy called "poisoning the well". It's not something you can debate. It's a subjective opinion, which you're entitled to, but it isn't debatable because it isn't logical. Suppose I say to you, "I don't believe in the theory of evolution." You ask, "Why?" And I answer you, "Well, it's obvious -- because evolution is a scientific theory and scientists have been wrong about so many things in the past. They were wrong about Piltdown Man, they were wrong about the coming Ice Age, they were wrong about the theory of the Ether. They've been wrong about so many things, why should I believe them now?"
