Why does a hypothesis need to be defined by the scientific method? I can pull an idea out of my butt (all grasshoppers are blue!), state it formally as a hypothesis and then apply scientific investigation to it. I don't see this bootstrap problem you're talking about.

Scientific method likely cannot resolve all possible categories of question, no. Empiricism is a fundamental assumption, that things are repeatable and hold true under investigation.

However this is a very different sort of assumption to the rejection of evidence based on faith that is implicit to creationism. One is our best effort to understand the world around us, the other is wilful ignorance.

Why does a hypothesis need to be defined by the scientific method?

Because a thing which you believe and yet is not defined by the scientific method (or rather, empiricism) is known as "faith", a concept which you and the rest of this thread has spent a good deal of energy attacking.

[Nursie]

A hypothesis is not something that you believe though, it is something subject to test.

[Karunamon]

And yet before you test it (if you get around to testing it, and you have the ability and resource to do so), it's just another thing you believe might be the cause of some effect.

In other words, it has no empirical base. It's an idea. A thought, held in the belief that some future action by you or others may prove it correct.

[Nursie]

Sure, it's an idea, it's not something you believe anything about though, that's a fundamental misunderstanding of the concept. A hypothesis is a statement of a possibility to be investigated and either upheld or invalidated. It is in no way equivalent to a belief.

[Karunamon]

I'm not seeing the substantial difference between those two things, aside from the unrelated-to-my-point variable of how much the idea-holder wants it to be upheld.

That variable certainly exists - it's why we have blind-controlled trials as the gold standard of research.

[Nursie]

Surely that's the whole point of a belief - here is something I know to be true.

As compared to a hypothesis - here is an idea that should be tested by investigation, I make no prior judgement to its truth

The underlying issue is that having faith in Empiricism(1) is reasonable but having faith in God is ignorance.
