The use of bibliometric indicators in research evaluation has a series of complex impacts on academic inquiry. These systems have gradually spread into a wide range of locations and disciplines, including the humanities. The aim of this study is to examine their effects as perceived by philosophy and ethics researchers in Spain, a country where bibliometric indicators have long been used to evaluate research. The study uses a mixed approach combining quantitative and qualitative data from a self-administered questionnaire completed by 201 researchers and from 14 in-depth interviews with researchers selected according to their affiliation, professional category, gender, and area of knowledge. Results show that the evaluation system is widely perceived to affect university researchers in significant ways, particularly related to publication habits (document type and publication language), the transformation of research agendas and the neglect of teaching work, as well as increasing research misconduct and negatively affecting mental health. Although to a lesser extent, other consequences included increased research productivity and enhanced transparency and impartiality in academic selection processes.
