People who believe in conspiracy theories are more likely to be involved in low-level crime, according to a new study.

While they have previously been associated with prejudice, political disengagement and environmental inaction, psychologists at the universities of Kent and Staffordshire said they can also make people more inclined to accept and actively engage in antisocial behaviour.

In a first study, the findings indicated that people who subscribed to them were more accepting of everyday crime, such as trying to claim for replacement items, refunds or compensation from a shop when they were not entitled to.

A second study concluded that exposure to conspiracy theories made people more likely to intend to engage in everyday crime in the future.

Publishing their findings in the British Journal of Social Psychology they said that this tendency was directly linked to an individual’s feeling of a lack of social cohesion or shared values, known as “anomie”.

Theorists claim that no wreckage from the American Airlines Boeing 747 was actually found at the scene and that first accounts of the explosion were later doctored by the government. Other allegedly tell-tale signs, such as several windows surviving the crash intact, indicate that the blast was smaller than you’d expect from an aeroplane crashing in to a building Getty Images The ten best conspiracy theories Shakespeare is “Sheik Zubair” Some claim that William Shakespeare is actually Sheikh Zubair from Basra, Iraq. Others claim he was actually Francis Bacon, Christopher Marlowe, William Stanley and the list goes on. The Bard's connection to Iraq, it is claimed, is evidenced by a resemblance in his work to the teachings of the Islamic Sufi sect: "All the historical data and even the time-line conclusively proves that Sheikh Zubair was an Iraqi poet and author of plays from Basra," one Independent blogger recently claimed Getty Images The ten best conspiracy theories “Free energy” suppression Some claim that advanced energy technologies are being suppressed by groups profiting from oil and gas production. Claimants say that the phenomena of "free energy" has derived from impressive discoveries in superconductivity of electricity which violates our current understanding of science and would make energy easier to produce and more efficient. Access to this energy is being restricted by the controllers of the current industry, and possible links to the New World Order have been suggested Getty Images The ten best conspiracy theories The Bermuda Triangle A number of aircraft and ships are alleged to have gone missing in mysterious circumstances in the Bermuda Triangle, or Devil's Triangle. Strange goings on and supernatural activity has been reported since the 1950s. Recent aircraft disappearances in the area include: a Puerto Rican owned aircraft carrying 12 people that went missing in December last year; and a Piper type aircraft on a medical transport run which was lost from the radar in April 2007 The ten best conspiracy theories New World Order Theories abound that the world's power and financial systems are actually controlled by occult secret societies including the Bilderberg group and the Freemasons. This theory seeks to expose collusion between businessmen and politicians in these societies promoting its secret agendas. Theorists claim that there are many "signs" confirming such claims, including Masonic symbols on buildings, and pagan symbols such as pentagrams worked into planning regulations in New York Getty Images The ten best conspiracy theories Tin foil hats Some believe that wearing a tin foil hat will shield the brain against mind control, mind reading and electromagnetic fields.Typically made from the aluminium foil most of us use to wrap sandwiches, the protective powers of the tin foil hat have reached such heights of fame that cyber versions are now available in the online universe of the game World of Warcraft. They come in all shapes and sizes and are totally customisable Reuters The ten best conspiracy theories Paul is dead There is an urban legend alleging that Paul McCartney of The Beatles died in 1966 and was replaced by a look-alike and sound-alike. Theorists say that clues have been planted in Beatles' lyrics ever since, including some "mumbling" by John Lennon recorded between the songs I'm So Tired and the next song Blackbird, which when played backwards allegedly sounds like 'Paul is a dead man. Miss him.' He was supposedly replaced by William Campbell- the winner of a look-alike contest Getty Images The ten best conspiracy theories Princess Diana's death Some believe that the death of Prince Charles' ex-wife in a Paris car crash 12 years ago was a murder plot by the Royal family to prevent her from marrying again. When Diana, her boyfriend Dodi Fayez and their driver were killed in 1997 both Fayez's father Mohamed al Fayed and Diana's former butler Paul Burrell added fuel to the claim that she was murdered. Theories that she had been pregnant and letters claiming Charles was plotting her murder were published posthumously Getty Images The ten best conspiracy theories The Roswell cover up Many believe that the US military covered up the crash of an alien spacecraft in Roswell, New Mexico, on July 8, 1947 by claiming that the "flying disc" it recovered was a weather balloon Getty Images

“Our research has shown for the first time the role that conspiracy theories can play in determining an individual’s attitude to everyday crime," said Professor Karen Douglas, of Kent’s School of Psychology. “It demonstrates that people subscribing to the view that others have conspired might be more inclined toward unethical actions.”
