They want complex solutions like correctly weighting and adding 50 factors, which are qualitatively different (e.g. price and deliciousness are hard to add), to figure out just the right credence that is further updated by any piece of evidence. Then they just end up factoring in a bunch of local optima, that, in the bigger picture, have excess capacity, so they shouldn’t actually change the result (the desire to always update the credence on any good or bad evidence is wrong! they don’t know you can have excess!). Besides quickly checking that many factors don’t ruin an option (giving pass/fail grades to things that are not near the borderline between pass and fail), you should focus your more detailed attention on just a few important factors, which is simpler than trying to use 50 factors.
