Background Genome scientists and Ethical, Legal, and Social Implications of genetics (ELSI) scholars commonly inhabit distinct research cultures – utilizing different research methods, asking different research questions, and valuing different types of knowledge. Collaborations between these two communities are frequently called for to enhance the ethical conduct of genomics research. Yet, little has been done to qualitatively compare genome scientists’ and ELSI scholars’ perspectives on collaborations with each other and the factors that may affect these collaborations.Methods 20 semi-structured interviews with (...) US-based genome scientists and ELSI scholars were conducted between June–September 2021. Interviews were analyzed using inductive thematic analysis.Results Genome scientists and ELSI scholars provided different understandings of the value and goals of their collaborations with each other. Genome scientists largely perceived ELSI expertise to be relevant for human subjects research; they described ELSI scholars as communicators who help the public and/or study participants better understand genomics research. In comparison, ELSI scholars viewed themselves as developing and implementing policies; they expressed frustration at how scientists can misunderstand their research methods or negatively perceive them. A combination of factors – both structural (e.g., criteria for promotion) and cultural (e.g., perceptions of what colleagues value and respect) – seemed to shape these diverging perspectives.Conclusion Academic institutions, funders, and researchers commonly call for collaborations between genome scientists and ELSI scholars, but under-consider how their different conceptual frameworks, research methods, goals, norms, and values, conjoin to affect such partnerships. Acknowledging, exploring, and addressing the complex interplay between these factors could help to more effectively facilitate collaborations between genome scientists and ELSI scholars. (shrink)
