Conspiracy. Just saying the word in conversation can make people politely edge away, looking for someone who won't corner them with wild theories about how Elvis, John F. Kennedy and Bigfoot are cryogenically frozen in an underground bunker.

But thanks to the social-media algorithms that push users toward ever-more-emotional, conspiratorial content, it's probably never been easier for false conspiracy theories to spread.
