"We must give full play to democracy and follow the mass line, trusting the judgement of the scientists and technicians in such matters as the evaluation of scientific papers, the assessment of the competence of professional personnel, the elaboration of plans for scientific research and the evaluation of research results. When views diverge on scholarly questions, we must follow the policy of “letting a hundred schools of thought contend” and encourage free discussion. In scientific and technical work, we must listen closely to the opinions of the experts and leave them free to use all their skills and talents so as to achieve better results and reduce our errors to the minimum."
