From Mao Zedong's "Opposing Bookism".

“Without investigation, there is no right to speak” is a frequently quoted famous saying by Comrade Mao Zedong, but few people know that a year after he said this, he also published the “General Political Department’s Decision on Population Survey” and Land Status Notice" further stated: "If you don't do a correct survey, you have no right to speak."

Adding the word "correct" in front of the survey makes it clear that the right to speak is obtained through survey and research. prerequisites, emphasizing the extreme importance of correctly conducting research.

Extended information:

Investigation and research are like medical consultation. Only correct diagnosis can grasp the disease. To deepen the reform of national defense and the military, conducting correct investigations and studies is the basic project and prerequisite. If accuracy is the goal that we should strive for when conducting research, then comprehensive and in-depth research is the bridge and ship leading to this goal.

If you give out investigation results at will and prescribe reform prescriptions indiscriminately without "seeing, hearing, asking and analyzing", it will delay the opportunity at best, and lead astray at worst. < /p>
