Over at Living the Scientific Life, the question was asked:
"I have sometimes heard it said that all kids are natural scientists (i.e., ask questions), but that most have it trained out of them as they grow up so that the few who become scientists as adults are the few whose ability to question is strong enough to survive this training."
Asking questions is the first step of science, but it is not science. After all, creationists ask questions all the time: how did the eye evolve, where are the transitional forms, if we evolved from monkeys then why do we have Larry King? None of this is science. It is far more like religion, where one asks questions, gets answers, and moves on.
What seperates science from other epistemologies is the insistence on setting up falsifiable experiments to answer those questions, and doing so in a way that others can replicate. This is decidedly NOT the way children think. Children do tend to ask questions, but they ask them of whatever authority they trust, and often accept the answer at face value. When they don't, they reason it out for themselves, as far as they are able. What they rarely do is go perform experiments to validate their theories.
I'm of the opinion that growing up, if you will, from this rationalistic mode of thinking, to doing real science is what is lacking from pseudoscientists of all ranks. Whether it is IDers/creationists, UFOlogists, or moonlanding conspiracy theorists, the common thread is rationalization, not science. In a sense, they never grew up, and still think like children. There is a reason Jesus said "suffer the children to come to me". He needed to get to them before they learned to do science, because once that happens, the gig is up.
The budding scientist isn't the kid asking you lots of questions, it's the kid digging in the ant mound to see what's there. After all, there is a reason science is done in peer-reviewed journals demanding detailed descriptions of replicable experiments. It is so anyone who doubts the results and wishes to replicate them can. Science is not satisfied with just questions and answers.
