Evolution, huh? Then where’s my crocoduck?
It’s absurd to suggest that primary school children should get any kind of sex education. Kids shouldn’t be watching porn until they’re old enough to find it for themselves on the internet.
Any psychics in the audience, please raise my hand.
Sometimes it’s really hard to argue properly against someone, especially when they’re making a lot of sense and presenting lots of supportive facts, and even more so if you yourself happen to be full of shit. But the great thing about logical fallacies is that you can quite merrily argue against someone else, someone with a much less defensible position, and still claim a victory.
Sounds so much easier than actually responding to your opponent’s points with sincerity and understanding, doesn’t it? Particularly when the someone else you’re arguing against doesn’t even exist, and is a mere hypothetical construct entirely conjured up by yourself, for the sole purpose of smacking them down and calling your real opponent a failure.
A straw man is just such a construct. Pretend that your opponent’s position is something different from what it actually is, and explain why they’re wrong for believing something that they don’t really believe.
It’s a popular one with creationists who misunderstand (willfully or otherwise) the claims of evolutionary science, and assert that the lack of any dogs seen giving birth to cats undermines anything Darwin might ever have written. (Actually, evolution doesn’t predict this should happen; in fact there’s nothing in the entire field of biology which could possibly explain something so bizarre.)
And it’s something which skeptics need to be careful of when questioning people’s unlikely-sounding claims about, say, paranormal abilities. Maybe it does seem strange how few psychics have ever won the lottery, but it could be that we’re just misunderstanding the nature of the claim, in the same way the creationists are.
This is why Randi is always so painstakingly scrupulous about getting a detailed description of exactly what an applicant says they can do, and under what conditions, before testing them for the Million Dollar Challenge – to paraphrase one of his own examples, it’s no use trying to prove that someone isn’t really a musician by sitting them down at a piano and demanding some Beethoven, if they claim to be a flautist.
