Surprised by either. Just finding a structure of causality that was very unexpected. I agree the intuition could be built from other sources.

PCA doesn't tell much about causality though. It just gives you a "natural" coordinate system where the variables are not linearly correlated.

Right, one needs to use additional information to determine causality.
