The observed trends in self-citation rates, particularly the increasing self-citation rates of Last Authors compared to First Authors, could have significant implications for the diversity and inclusivity of the Neuroscience research community. As Last Authors are typically more senior researchers, often in positions of power and influence, their higher self-citation rates may perpetuate existing hierarchies within the field. This trend could disadvantage early-career researchers, who are often First Authors, by limiting their visibility and recognition in a competitive academic landscape.
Moreover, the lower self-citation rates observed in low- and middle-income countries (LMICs) may further exacerbate disparities in representation and influence within the global Neuroscience community. Researchers from LMICs may struggle to gain recognition and funding opportunities, leading to a lack of diversity in research perspectives and topics. This could ultimately hinder the advancement of Neuroscience as a field, as diverse viewpoints are essential for fostering innovation and addressing complex scientific questions.
In the long run, if these trends continue unchecked, they may reinforce existing biases and inequities, making it more challenging for underrepresented groups, including women and researchers from LMICs, to establish themselves and thrive in the academic environment. This could lead to a homogenization of research outputs and a narrowing of the scientific discourse, which is detrimental to the overall progress of the field.
