@tao@mathstodon.xyz I see @johncarlosbaez@mathstodon.xyz beat me to the point :-) Elaborating on it, I also want to add that the method you propose will carry an intrinsic discrimination of those with what we call in Britain 'protected characteristics' (ethnic background, gender, sex, parents, etc). At the LMS we had to create a policy for conferences that we fund which explicitly requested the inclusion of women. Many don't manage more than 25%. Thus your suggestion would further reduce the amount of due credit women get.
