In this paper, we engage with five Swedish universities' discursive articulation of, and responses to, an alleged post-truth crisis in communication, aimed at the public. Taking discourse theory as our point of departure, the aim is to analyse how universities are trying to maintain or restore trustworthiness against a backdrop of problems with fact resistance, fake news, and mistrust in academic institutions. The dilemma for universities is how to counteract post-truth without falling into the trap of returning to a realist paradigm, with its strict notions of truth and objectivity. The paper shows how public events are characterised by a crisis rhetoric, a dislocation, together with imaginaries of both external and internal threats of disorder, which convey a narrow and simplified understanding of scientific knowledge as objective and neutral. "Defenders of truth" seem to foreclose any discussion by deeming knowledge relativism an irrational and dangerous position that fuels arguments claiming a truth crisis. A conclusion is that universities risk increasing polarisation, rather than trying to tackle problems of trustworthiness. The authors argue that, instead, universities need to be attentive to matters of democracy, power, and privilege, as well as a plurality of epistemological ideals, when discussing the so-called post-truth crisis.
