Scientist engagement and the knowledge–action gap


Abstract

The combined gravity of biodiversity loss and climate change keeps increasing. As the approaching catastrophe has never looked so alarming, the amount of scientific knowledge about the bioclimatic crisis is still rising exponentially. Here we reflect on how researchers in ecology or climate science behave amid this crisis. In face of the disproportionality between how much scientists know and how little they engage, we discuss four barriers that may underlie the decoupling of scientific awareness from concrete action. We then reflect on the potency of rational thinking to trigger engagement on its own, and question whether more scientific knowledge can be the tipping point towards radical changes within society. Our observations challenge the tenet that a better understanding of what surrounds us is necessary to protect it efficiently. With the environmental cost of scientific research itself as an additional factor that must be considered, we suggest there is an urgent need for researchers to collectively reflect on their situation and decide how to redirect their actions.

Contributions

Positionality statement: L.D. is a 27-year-old PhD student in ecology and evolution and intends to depart from academia afterwards. S.J. is a 36-year-old permanent CNRS researcher in ecology and evolution, specialized in phenotypic plasticity and dispersal. H.P. is a 59-year-old permanent CNRS researcher in the field of phylogenomics, but has been working on the topic of scientific degrowth for 15 years. Both Staffan and Hervé have children. All three of them identify as males, live in France and do not belong to a racialized minority. They regularly take part in activism, but do not feel sufficiently engaged. All three of them deem that tackling the bioclimatic crisis is of greater importance than accumulating more knowledge. Their research has been funded by public agencies for the past 10 years at least.
