As an institution of knowledge production science provides a quite efficient incentive scheme for the production and disclosure of public knowledge society needs. The workings of the incentive mechanism are based on priority-based reward system. This system is incentive compatible with the norm of public disclosure from static point of view while it is not necessarily incentive compatible with the same norm from dynamic point of view.. To solve this problem, the priority of discovery needs the help of communism as the culture of science so as to increase the efficiency of knowledge production and to make the public disclosure of knowledge more quickly.
