I have received several requests to take a look at or try to improve lottery or gambling systems. The requests were private and their authors did not want to make public their ideas. They have a point, but it's not a strong point. I know how humans function. Humans have progressed, in great part, because they make public their efforts .
Effort here has a generalized meaning.
That's not pure generosity. We make our efforts public because we expect positive consequences that serve us. The FearSurvival system is selfish, to be sure, even when it shows signs of unselfishness. Speaking from my personal experience. I am not at a loss.
