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.
