How has neoliberalism weakened science?

The current Covid-19 pandemic, and before that, the environmental crisis due to climate change, raise major questions about the relationship between science and society. More than ever, public opinions in OCDE countries question the legitimacy of scientists and scientific knowledge. The reasons for this fracture are obviously multiple and complex, but we believe that applying neoliberalism principles to research has contributed to it. In this article, we show how the funding of research by private institutions, staff precariousness, the ‘publish or perish’ policy have changed the way in which scientific knowledge is produced and decreased the confidence of citizens regarding scientific output. We believe it is high time to launch a wide debate on these issues within the scientific community. We should take advantage of both the climate and the health crises to put fundamental scientific issues and the role of scientists in society back on the table, so that science as a social activity (production and diffusion) is taken back into the hands of scientists in public institutions where conflicts with private interests are limited.
