Not long after Bill Clinton became president, rumors began circulating that he had covered up the existence of a cocaine-smuggling operation in Mena, Arkansas, when he was governor. It wasn’t true, of course. But the Clinton conspiracy theorists—yes, they have ever been among us—began badgering newsrooms and demanding to know why this galactically important story wasn’t being investigated.
Now there are growing concerns about the rise of fake news on the internet, and especially on Facebook. I think we all need to be worried about the effect that false information has on our democracy. And there’s no doubt that Facebook, with its 1.8 billion users, has weaponized the spread of conspiracy theories in a way that wasn’t possible previously. But the Mena craziness, which lives on to this day, shows that the internet is not now and never was a necessary precondition for the spread of politically motivated falsehoods.
