You can remove correlated predictors or do stepwise regression to get a minimal model with more intelligible coefficients.
The problem is it's still difficult to determine direction of causality. That's why controlled experiments are so important.
Aren't we supposed to remove correlated predictors from models?
Or we can use techniques like PCA? But then, once again, we fall into the realm of unexplainable.
