Absurd as these ideas might seem, they're quite common. Polls show at least half of all Americans believe in at least one conspiracy theory, even when there's no credible or convincing evidence.
Why? The Christian Science Monitor's Patrik Jonsson suggests it's in our very nature as Americans, writing: "In a country where the Founding Fathers' distrust of government is enshrined in the Constitution, conspiracy theories often give wider scope to that worldview."
Still, you'd think in the age of the Internet, some of the more out-there theories would be laid to rest.
But confirmation bias — the idea that we seek out confirmation, not information — is a very real thing. And Google hasn't helped.
As The New York Times' Maggie Koerth-Baker puts it: "It can be comforting to do your own research even if that research is flawed. It feels good to be the wise old goat in a flock of sheep."
But of all the conspiracy theories, doubts surrounding Kennedy's death resonate the most. A recent poll found 59 percent of Americans believe there's more to the story — the U.S. secretary of state included.

So what makes JFK so different? Writing in The Washington Post, two University of Miami political scientists theorize: "The victim was an American president and the potential villains include actors of immense reach and influence. … Anyone, regardless of political affiliation, can find a detested powerful actor to blame."
In other words, the idea that the American president could be taken down by a lone shooter may be too hard to swallow. The conspiracy theories, however crazy they may be, in a way give us comfort. (Via John F. Kennedy Presidential Library)
But perhaps it was Kennedy himself who said it best: "For the great enemy of truth is very often not the lie — deliberate, contrived and dishonest — but the myth — persistent, persuasive, and unrealistic." (Via John F. Kennedy Presidential Library)
