Many people, when they hear the word propaganda, immediately associate it with Nazi Germany and torchlight parades or Putin reviewing the troops in Red Square. But propaganda has Roman Catholic church origins going as far back as 1622, when Pope Gregory issued a proclamation using the term to exhort the faithful to propagate the faith. Today, propaganda is disseminated far and wide through the internet. It is used by autocrats to shield themselves and their policies from public view. Bots are at work. Malicious actors spread fake news. Deceptive techniques are so sophisticated that it is sometimes difficult to separate fact from fiction. Misinformation is eroding public trust in institutions and stressing and straining democracy. Stories are planted, rumors are spread, lies are told, and narratives are laundered.
