        @paulg Works only with infinite pools of applicants. If First Round funded 100% of elite college students, could still get same results

        @terzicigor In practice not. In practice there is a huge supply of people who went to elite colleges yet aren't very good.

        @tommyjensen I didn't learn about it from someone else, but I would be surprised if no one else had thought of it.

        @paulg Problem: If one group *is* inherently better than another, you would expect better perf from that group even under fair selection

        @paulg So this test works for groups you expect to be roughly equal (men/women?) but not for those you expect to be different (colleges)

        @jasoncrawford Yes, that's right. Though in my experience alumni of different colleges don't vary as much as the colleges' brands imply.

        @paulg Does the converse work? If a subgroup underperforms, does that imply a positive bias?

        Replying to @geepokey

        @geepokey Yes, but because of the definition of bias rather than any feature of this technique.

        @paulg @geepokey There's also some probability that it'd happen by chance in an unbiased selection process.

        @paulg After some thought, I don't think this method is robust against an active adversary seeking to hide bias against select subgroups.

        @paulg I think you'd have to consider the sub-group distributions and make sure that they are at least the same shape.

        @g33kbeast Do you mean precondition (c) or something else?

        Replying to @paulg

        @paulg Even if (c) is true, someone trying to hide bias can mess with selection process. Simpson's paradox in reverse.

        @paulg if women are discriminated against on exits/next rounds, it lowers the bias measure in FRC example

        @inazarova @paulg Or any other discrimination along the way. The original idea is crisp and clever, but fails for this reason, IMO.

        @davidhelgason @inazarova @paulg W/o further discrimination performance would be even stronger. So, w/discrimination bias measure is higher?

        @paulg super clever. Said another way, reversion to the mean should be present if sample not biased, and if it's not there may be a reason

        @paulg Sama data also imply Investor bias *against* youth (< 25 years old) despite Conventional Wisdom being the opposite.
