'What Kuhn pointed out was that the scientists don't operate the way that you would expect that they do according to Popper, looking for refutations, and once they get a refutation (that is, some observational result which clashes with their theories), they give up the theory. Kuhn talked about scientists treating apparently negative results as anomalies rather than refutation. '

An excellent analysis, John! Thank you!

A story caricatures the much revered scientific method. "A scientist methodically studies the behaviour of a flea. He first orders it to jump: "Jump! ". The flea jumped as expected. He then cuts off its legs to see if they play an important role in its response: He then orders it to jump: "Jump! ". But the flea does not jump. So the scientist carefully notes in his notebook: "When you cut off the flea's legs, it becomes deaf. "

Haha, that's ironic. This story warns against non-scientific approach to science, and against religion-ridden morons like you who don't understand what the scientific method is. Specifically, it warns that in a controlled experiment, all the variables must be properly controlled and accounted for. When testing for the effect of variable A, you must make sure variables B, C and D remain unchanged, or your experiment will be vitiated.
