The CLT allows anyone (including ignorant economists and psychologists) to do statistics by using prepackaged recipes coming from the Gaussian. What are the foundations? How does it work? Where does it not work?
Everything in empirical science is based on the law of large numbers. Remember that it fails under fat tails.
SIMPLIFIED TUTORIAL, 1 (in the series where we break down concepts intuitively):
Before we talk about correlation, let’s discuss standard deviation, its analog in dimension 1. People don’t get while using it as a metric for deviation!

Most of the tension resides between 1) Embedded, complexity-minded, multiscale/fractal localism (politics as an ecology/complex adaptive system), and 2) Abstract one-dimensional universalists and monoculturalism (politics as a top-down engineering project). We go beyond the verbalism; we rely on information theory, complexity theory, uncertainty approaches (say fragility), and probabilistic rigor to look at politics with the same eyes as we examine highly dimensional interactive elements such as nature, biological systems, internet networks, and medical issues.
