The best conspiracy theories are like enchanting mazes of logic whose thresholds, once crossed, are hard to return from. As ludicrous as they can appear from a distance, the closer you get, the stronger their gravity and the greater the danger of being sucked in. How else to describe the extraordinary rebirth of David Icke? Best known to some as the former BBC sports presenter who appeared on Wogan in a turquoise tracksuit implying he might be the son of God, to the post-Twin Towers generation he’s the visionary master of conspiracy, performing his unscripted 10-hour lecture about the secret forces that rule the world to sell-out crowds at Wembley Arena.
A 2011 BBC poll found that 14 per cent of Britons believed 9/11 was an inside job. Just as conspiracy websites are flourishing, so are those dedicated to undermining them, such as Snopes, The Skeptic’s Dictionary and Skeptoid. The number one debunking podcast on iTunes, The Skeptic’s Guide to the Universe, claims a weekly listenership of 120,000 and tens of millions of downloads since its 2005 launch.
Icke often describes his work as “dot connecting”. But connecting dots is precisely how all sorts of mistakes about reality arise. “Our brains evolved to spot patterns in the environment and weave them into coherent stories,” says psychologist and conspiracy theory expert Dr Rob Brotherton. “We’re all conspiracy theorists because of the way our minds work. It’s how we make sense of the world. But it’s easy to connect dots that shouldn’t be connected.”So humans are rampant dodgy dot connectors, and they also suffer from an array of biases that make them susceptible to faulty belief. “We’re biased towards seeing intentions in the world, to think things were done deliberately instead of being chaotic,” says Dr Brotherton.
“There’s also a proportionality bias, so we want to think that when something big happens in the world it has a big explanation. In the case of JFK, you don’t want to believe some guy you’ve never heard of killed the most important man in the world and changed the course of history. Another is confirmation bias – when we get an idea in our head it’s very easy to find evidence that seems to support it. It takes a very unusual mind to de-convince itself. We’re made to believe.”
And some of the theories out there at the moment really take some believing. Here are five: . . .
