Trump lies and we all know it. He lied about Russian business ties. He lied about his inauguration numbers. He lied about terror attacks in Sweden, and lied about forest fires in Finland. There seems to be no end to it all. The public, at large, have come to shrug off any new lie, just as the law of diminishing returns would lead us to predict. But with the advent of Trump, we were told, came also the final victory of the proponents of “post-truth”.
