As I see it, rationality is much more about choosing the right things to use one’s success for than it is about achieving success (in the conventional sense). Hopefully it also helps with the latter, but it may well be that rationality is detrimental to people’s pursuit of various myopic, egoist, and parochial goals that they have, but that they would reject or downgrade in importance if they were more rational.
