All this post says is that among the candidates who scored highest on this model, a higher proportion worked at these companies.

But there's no inverse analysis: of people who worked at these companies, how predictive was that overall of a higher score on this particular assessment?

'Our five highest scores ever were all people who wanted to leave FooCo' tells you little about the overall quality of FooCo employees. Maybe the rest of them are terrible and these five needed to get away?



No you're misinterpreting it. Go back and reread the graphs.


Ah, you're right. The graphs don't actually show the data they describe their methodology as collecting. That fills me with confidence.
