Compared with science and engineering majors, the number of liberal arts majors is relatively small. We can't say which major's master thesis is better or worse. There is specialization in the technical field, and the key depends on the quality of master's thesis. However, it is undeniable that compared with science and engineering papers, the space for selecting topics in liberal arts papers is smaller, or it is more difficult to collect data in paper practice than in science and engineering. Science and engineering papers can be compiled through the experimental data of the topic, and the theoretical support of liberal arts is really difficult. As for whether it is good or bad, one is the quality of the paper, and the other is the measure of the defense teacher.
