Abstract
This article aims to diversify STS perspectives on populism by addressing a sequence of episodes of Mexican science policy in terms of clashes between populism and scientific communities. The article describes a reorientation of Mexican science policy that has destabilized the academic system during the present administration. Specifically, it looks at the legislative project initiated by Mexico's National Science and Technology Council (Conacyt) to overhaul the national regulatory framework on science, technology and innovation, and controversial political actions taken by Conacyt against the scientific community. Contextualizing these grievances, the article concludes that at stake is a form of 'trickle-down populism' that, through systematic authoritarianism, seeks to impose on the academic community a model of 'populist science governance'.
