Fake Regression by Psychologists

Fake Regression by Psychologists (Fooled by Randomness), Based on the paper on Trust by Nicolas Baumard

How to detect fake regressions. Never pay attention to numbers before looking at the graph.

First I show how to spot fakes in a sinister paper by Nicolas Baumard et. al. linking people’s physical traits to (un)trusworthiness.

Second, more technically, I derive the distribution of the slope between two random variables and show how one can game it.

[YouTube] Ellipticality (Technical)

Modern financial theory assumes that distributions are elliptical. We show what happens if the assumption doesn’t hold. And the assumption doesn’t hold.

Diversification does NOT reduce risks in the financial market; it causes near-certain long term blowups under any leverage.

Never use Single-point Estimates for Pandemics

Never produce a point estimate for risk management, esp. in a fat-tailed domain, rather show statistical properties. Never judge a risk management stance from point forecasts.
