Correlation

I disagree. That may be the case in social sciences, but finance is an entirely different phenomenon. Theory fits the data almost perfectly, modulo a few “blind points”. Thus, causation can be captured by correlation.
I don’t necessarily understand you point. Are you suggesting that eg the NBER commentary is simply a correlation, or has had an effect on ‘recession’ thinking?
