The Brain has a comment on Scott Page’-s presentation [PPT file] about his book, The Difference:
One question is whether there is a way to usefully systematize that principle by trader selection or via something other than a strict market such as an (incentivised) weighted average system like HP’s BRAIN. The latter type of system will work better in some domains but in general might be less robust because it constantly runs the danger of being overfit to past trader correlations (or apparent expertise, risk appetites, etc). In general, trader self-selection and self-weighting might be more accurate. If you have some metric of “fundamental” trader similarity like proximity, org chart relations, demographic data – as opposed to past trading correlations only, that might work better in terms of expert-selection/expert-weighting.
