Because in the process of blind evaluation, the evaluation experts can only judge according to the academic value and quality of the paper itself, and cannot be influenced by the author's identity, experience or other factors, so the evaluation is more fair and objective. In the process of defense, experts may be influenced by the author's performance and tone, and there may be subjective factors in judging the quality of the paper.

First, the introduction of blind trial:

1, blind evaluation is a Chinese word, which refers to a system of organizing expert group evaluation, that is, anonymous submission, which means that the evaluation tutor does not know who the author of the paper is. In this way, the false positive rate of scores is low, which is generally used in college marking.

2. The blind evaluation system is to send dissertations without the author's name to unknown experts, so the score should be the most objective. General colleges and universities, especially graduate schools, have relevant regulations on blind evaluation of dissertations on a regular basis, and most of them randomly select a certain number of papers for blind evaluation.

3. The right of reply can only be obtained after the blind trial and the external trial are passed. If the defense fails, you can't graduate. As long as two experts pass the blind trial or two experts pass the external trial, they can get the right of reply. The defense Committee does not include external experts, and half of them can graduate.

Second, the blind trial situation:

1, doctors and masters cannot graduate, but the proportion of masters is very small, and some masters have not graduated, but the proportion is less than 1%. All doctoral dissertations and some master's dissertations are sent to foreign units for blind evaluation by the degree office before the defense to ensure the quality of the defense thesis.

2. In addition, the provincial and municipal education committees will randomly select a certain proportion of papers and invite other units to do blind evaluation to check the quality of postgraduate training. All doctoral and master's dissertations can only participate in the defense after passing the blind external trial, and then the defense Committee decides whether to pass the defense or not to award the degree.
