Barbara Fister writes: “As the denouement of the 2020 presidential race presented voters with wildly different claims about the validity of election results, feeding an eruption of violence as Congress convened to complete the work of the Electoral College and confirm Joe Biden as president, many stunned observers demanded to know where we went wrong. How could so many people believe things that are obviously untrue? Why don’t kids learn about this in school? Shouldn’t being able to navigate information and separate truth from lies be a standard part of education? It is. It has been, for a long time. It clearly hasn’t worked.”
