Abstract: Postgraduate thesis development is a rigorous and comprehensive process that involves the conception, planning, research, writing, and defense of a scholarly work at the postgraduate level. Nevertheless, despite the increasing interest in developing postgraduate theses, there is a notable deficiency in research regarding their comprehension within the realm of dark psychology. The objective of this study is to review the dark psychology in postgraduate thesis development. The methodology for this study using content analysis would involve several steps. Firstly, a comprehensive literature search would be conducted using databases such as PsycINFO, JSTOR, PubMed, and Google Scholar. This study found that there are five potential areas of exploration related to the darker aspects of psychology in the context of postgraduate thesis development: (a) isolation and loneliness; (b) impostor syndrome; (c) perfectionism and procrastination; (d) toxic mentorship; and (e) burnout and work-life imbalance. In conclusion, this study has shed light on a previously underexplored area of psychology. Future studies on this topic could consider several avenues for exploration.
