Paper: SCALA POLITICA – Politics and Governance Under Scaling and Uncertainty
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.

Paper: On single point forecasts for fat-tailed variables
Abstract
We discuss common errors and fallacies when using naive “evidence based” empiricism and point forecasts for fat-tailed variables, as well as the insufficiency of using naive first-order scientific methods for tail risk management.
We use the COVID-19 pandemic as the background for the discussion and as an example of a phenomenon characterized by a multiplicative nature, and what mitigating policies must result from the statistical properties and associated risks. In doing so, we also respond to the points raised by Ioannidis et al. (2020).
