David Colarusso"The Robust Beauty of Improper Linear Models in Decision Making" lives rent free in my mind. I think about this paper from 1979 ALL. THE. TIME!
TL;DR: experts can make robust linear models by just picking a few salient features from their experience. See https://www.cmu.edu/dietrich/sds/docs/dawes/the-robust-beauty-of-improper-linear-models-in-decision-making.pdf
In today's parlance the TL;DR would read "feature selection is really important."
