The financial crash of 2008 and the pandemic of 2020 have been moments of great clarity, when the claims of competence of the elites and the experts have been exposed as hollow. The rhetorical style of the industrial age was utopian: if only we mix the right amount of data with great enough power, we can fix the human condition. That illusion should have vanished when the Soviet Union went out of business but, perversely, it has clung to political debates in democratic societies. We should know by now that human knowledge is frail and limited. A little humility in elite rhetoric would go a long way towards restoring trust.
