Raising the sanity waterline is an instrumental goal. A deeper goal is “have more [effective mindpower] applied where it is needed”. This can be achieved by increasing the [effective mindpower] of each person, or by routing people with already-high [effective mindpower] to more important and difficult work. To do the latter without an authoritarian system (which would probably fail anyway), we need people with high [effective mindpower] to be aware of this so that they can look for important and difficult work. The OP makes progress in the area of “increasing the accuracy of beliefs about one’s capabilities”.
