If the number of deontologists isn't big enough to power our inference, the stats should tell us this. There are some though.

That's true. Perhaps we could sort them by what their results with "good" show us about which normative ethical theory they follow, then compare the results of each of the groupings between "good" and "awesome". That would show us the results without consequentialists acting as white noise.

And I think going outside LW is unnecessary. This essay is hardly aimed at people-in-general.

Good point, though it would be interesting to see if it could be applied to people outside of LW.
