First of all, doctoral students are facing great pressure and challenges in the process of studying for doctoral degrees. They need to complete a lot of research work, write high-quality papers, and pass strict defense procedures to get their degrees. These requirements make many doctoral students feel tired and even have psychological problems. In addition, because the research direction of doctoral students is often narrow, they may find limited employment opportunities in their professional fields after graduation, which will also affect their satisfaction with their doctoral degrees.
Secondly, doctoral students may encounter problems such as insufficient guidance from tutors and lack of resources in the process of studying for doctoral degrees. These problems may lead to the slow progress of doctoral research and even the failure to complete the dissertation. In this case, doctoral students may have doubts and dissatisfaction with their doctoral degrees.
In addition, the expectations of the society for doctoral degrees are also constantly improving. In the past, having a doctorate meant that a person had profound professional knowledge and skills in a certain field. However, with the popularization of higher education and the development of knowledge economy, more and more people begin to study for master's or doctoral degrees. This makes the value of doctor's degree decline relatively, and people's expectations for doctor's degree become more demanding.
Finally, doctoral students may face the confusion of career planning in the process of studying for doctoral degrees. Because the research direction of doctoral students is often professional and narrow, they may find that their employment opportunities in their professional fields are limited after graduation. In addition, because doctoral students spend a lot of time and energy in the process of studying for doctoral degrees, they may miss other opportunities for career development. These problems may cause doctoral students to have doubts and dissatisfaction with their doctoral degrees.
