Scientists replicate each other’s experiments in order to prove or disprove their findings. Conversely, journalists replicate one another conclusions and build on top of them—often when they are not correct. The news has always filled with errors, because it is self-referential instead of self-critical. Mistakes don’t occur as isolated incidents but ripple through the news, sometimes with painful consequences.
