Why we should all be reflexive: The case for reflexivity in quantitative science

While reflexivity is an established hallmark of good scientific practice in qualitative research, it is practically non-existent in predominantly quantitative fields. Here, I argue that an awareness and acknowledgement of researchers’ influence on their work could contribute substantially to the quality of quantitative research. Basing my argument on the widely held values of transparency and rigour and corroborating my further premises with evidence and reasoning from metascience and the history, sociology and philosophy of science, I conclude that reflexivity ought to be endorsed by quantitative researchers, too. To illustrate the implementation of reflexivity, opportunities for its gainful application in a quantitative demonstration example are provided. Moreover, I highlight potential challenges for reflexive practices arising from current incentive structures and epistemic injustice but also discuss how reflexivity should contribute to its dismantling. Finally, I argue that the well-developed method of reflexivity offers a very convenient tool to quantitative scientists to strive for greater rigour and transparency.
