Background: Codes of conduct for research integrity provide ambivalent guidance on the role that the values of society as well as political and economic interests can or should play in scientific research. The development of clearer guidance on this matter in the future should consider the attitudes of researchers.Methods: We conducted 24 semi-structured interviews with holders of grants from the European Research Council and performed an inductive thematic analysis thereof.Results: We developed 4 themes reflecting 4 main attitudes of researchers toward the interactions between values and science: awareness, concern, confidence, and embracement. While interviewees recognized that science is not completely value-free (awareness), they still seemed to hold on to the so-called value-free ideal of science as a professional norm to minimize bias (concern, confidence). However, they showed awareness of the beneficial influence that values like diversity can have on research (embracement).Conclusions: Codes such as the European Code of Conduct for Research Integrity tend not to problematize the tensions that emerge from having the value-free ideal of science as a norm and being guided by the values of society. Our findings suggest the time might be ripe for research integrity codes to address more directly the value issues intrinsic to science.
