everyone's begging for an answer

"Don't tell me about the answer,
'cause then another one will come along soon,
I don't believe you have the answer,
I've got ideas too,
But if you've got enough naivete,
And you've got conviction,
Then the answer is perfect for you"

It all depends what this is referring to. As a general rule it is bad as you wind up in the position of denying progress based on the hypothetical improvements that have yet to come.
Did we do nothing we Newton's mechnaics because Einstein's would come along later? Nope.
Should we stop using Einstein's as a better one may be around the bend? Nope.

Whilst it does accurately convey the constant improving nature of human knowledge, to deny the exploitation of current knowledge based on the possibility of having some better knowledge is just plain silly.

Though it does accurately reflect the sceptical nature you should have of some of the "answers" that we are presented with. Astrotheology, 'the secret' etc. are a dime a dozen and perhaps should be treated like this song suggests.

To summarise: an accurate description of advancing human knowledge that could lead to the culling of human progress if applied to liberally, but in the right amounts helps weed out bad ideas.

But then the question arises; what makes a bad idea?

That really depends on each idea, but a good 'yardstick' is whether it requires faith for you to accept it as true.

Of course, this may upset some people, particularly those of a religious nature.

But this is merely because of a misunderstanding. "Faith" is the state of belief where you have no evidence, proof or justification for that belief. Most religionists have a justification, some proof or evidence of their chosen belief.

Of course, nowadays faith has been equated to religious belief to the extent that it is one and the same. I do not use it in this context. When I refer to faith I do so as when you have a belief with no evidence at all, rather than when you have a belief in a religion.

So by the old definition, which I use now, most religious types are excluded.

In fact, almost everything is excluded.

But not everything. Some ideas still require you to pause your evidentiary standards.

Some require the old style faith

Those are the bad ideas
