Pls show examples where increasing brightness in post better than increasing ISO.

The simple fact is
that you have to choose: will you sacrifice the highlights or the shadows. With a scene where the DR is beyond what your camera can capture in a single exposure, this choice is of greater importance than what ISO routine you prefer.

Do you want to preserve highlights it is often better to choose underexposure at low ISO, at the cost of shadow colour and noise (esp. banding). If shadows are more important it is often better to choose high ISO, at the cost of highlight rendering.

Heavy shadow lifting commonly leeds to colour shift and banding noise, at least with badly lit scenery where major parts of the image is in deep shadow.
In daylight situations with minor parts of the image in deep shadow, lifting in post is mostly not a problem (unless you have an ISO-full camera).

These are my findings, based on extensive practice and not on science.

The point about knowing the science is that it lets you take out of the loop a lot of the 'extensive practice'.

Extensive practice has a lot of other benefits. You need 10 000 hours of practice (whatever you engage in) to get proficient. Try it.

That's afigure plucked out of the air with no evidence.

Actually not

The point is that science provides direction much faster than trial and error.

There is no such contradiction. Most science is based on trial and error.

Well, a lot of engineering is trial and error. And trial and error has indeed helped science. But the major breakthroughs that have led to modern science, special and general relativity and quantum mechanics, are hardly trial and error. These Kuhn-sian revolutions are greatly thought beyond trial.

Even thought-processes can be, and often are, trial and error.
And how would you categorise the search for the Higgs particle...

Difficult. But, seriously, how would you characterize the "knowledge" that the Higgs particle was even worth searching for?

The would have been interesting.

'Let's build a $6Bn machine, just in case something interesting happens when we smash atoms together at huge energies'.

If you take out the words "just in case", that´s pretty much it. It´s called "basic research".
And it´s not like the scientists involved payed for it out of their own pockets.

Even if the Higgs particle hadn´t been found, LHC would still be worth the cost and effort.

'OK, which sensors should we fit on it?'

'Dunno, see what you can find on ebay, else it might cost $7Bn'
