Even if there is a model that performs well, how do you account for survivorship bias?
And how accurate are models without a clear understanding of the physical reasons why behind them?
Seems like we should be concentrating on understanding the physical relationships and less on trying to come up with abstract models. It kind of feels like a bunch of astrologists and just picking the one that seems to perform better.
Unless I understand the why, I have a hard time accepting what anyone says.

Anyone can fit a model to the data.
