Faked moon landing, #PizzaGate, September 11 was an inside job, Vince Foster was murdered by the Clintons to cover up Whitewater, the Sandy Hook massacre was a hoax - the list of conspiracy theories is long and bizarre.

Side-show paranoid nonsense becomes alarming and enraging, however, when ordinary people base important decisions; how they vote, for example, on whatever fevered internet story best supports their own personal world views.

On Thursday, the U.S. government released 2,891 documents on the assassination of John F. Kennedy and let's be real: you're probably not going to read them. So here are the juicy bits according to the people who already have.

Computers believe in conspiracy theories now. The New Inquiry's Francis Tseng trained a bot to recognise patterns in photos and draw links between similar pictures, forming the kind of conspiracy-theory diagram seen in the last act of a Homeland episode or the front page of Reddit. It's a cute trick that reminds us that humans are gullible (hey, maybe those photos do match!), and that the machines we train to think for us could end up just as gullible.
