Seems to be the physics way of looking at the world. Don't trust potentially accidental empirical observations, because they might fail you in a relativistic universe in which there isn't even such a thing as simultaneity (all swans are white until one isn't).

Only trust fundamental truths / laws of nature, as they govern what works / doesn't and prescribe fubdamental constraints on how the world works - most likely anytime, anywhere and independent of a particular context.

So the expert looks at the world and says: everyone is doing agile, so what you have to do is agile. Replies the scientist... It depends!
