Very interesting video (as an aside the title should probably have the [video] tag). The outcome of the toy model for astronaut selection is very interesting: when the competition is stiff, the "luck score", even when weighted much lower than other factors, can have an outsized effect on the final results. That fits my priors quite well: most successful people I know work very hard and had quite a bit of luck along the way.
