In a recent opinion article, sustainability researcher orjan Bodin claims that a shift leftward in sustainability science has rendered certain topics and research methods taboo, thus inhibiting the field's ability to contribute to achieving Agenda 2030. In this response, we problematise Bodin's framing of sustainability science, arguing he has misrepresented the field as "normal" rather than acknowledging its unparadigmatic character. It is precisely the unparadigmatic character of sustainability sciences (plural emphasised) that allows the field to begin addressing the wicked problems of our time. The question is then how to "disagree well" and assure quality in this unparadigmatic field.
