9-11 was an inside job. The moon landing was faked. Vaccines cause autism. These are just a few of the most well-known conspiracy theories perpetuated by otherwise intelligent, everyday people. But why do some people believe these things and others don’t? Scientists are one step closer to figuring that out, and it appears that the answer lies within the brains of the theorists’ themselves, which affects how they see they world.
Scientists had long hypothesized that conspiracy theory belief (which the researchers of a new paper define as “the assumption that a group of people colludes together in secret to attain evil goals”) was due to a phenomenon known as “illusory pattern perception” — seeing patterns where none really exist. But few studies had been done to support this. So, the British and Dutch scientists conducted a series of experiments to fill that void. Their paper was published recently in the European Journal of Social Psychology.

For 10 years, Nancy drank diet soda — sometimes as many as four or five a day. Otherwise, she ate and drank in moderation, exercised regularly and got plenty of sleep. Then one day, as Nancy picked up her glass of diet soda, it slipped from her fingers and crashed to the floor. Shocked, Nancy tried again, only to discover her hand wouldn’t properly respond. The problems subsisted for weeks, then her legs began to buckle and her vision to blur. Eventually, Nancy’s doctor diagnosed her with multiple sclerosis (MS), a disease that affects the brain, spinal cord and optic nerves.
Desperate to know more about MS, Nancy scoured the Internet for answers. She learned MS usually strikes between ages 20 and 40, that it affects women more often than men and that scientists don’t yet understand its root cause (source: WebMD). Then she came across an obscure message board and realized she might have a clue after all. There might be a link between aspartame and MS. Wasn’t that the ingredient in all the diet sodas she’d had over the years?
While the Multiple Sclerosis Foundation stops short of saying aspartame — or any additive, for that matter — is 100 percent safe, it doesn’t subscribe to the notion that aspartame causes MS. Aspartame was approved by the U.S. Food and Drug Administration (FDA) for use in carbonated beverages, and other beverages and foods in the 1980s. After a volley of complaints from consumers experiencing everything from insomnia to diarrhea after ingesting carbonated beverages containing aspartame, the Centers for Disease Control and Prevention (CDC) investigated aspartame’s use and concluded there wasn’t any evidence that it caused these symptoms. More to the point, the CDC failed to find a link between aspartame and the onset of MS (source: Guthrie).
The idea that aspartame causes MS most likely stems from a supposed first-hand account of an aspartame expert that has persisted on the Internet and in chain e-mails since the 1990s. Although this article is frequently attributed to the author “Nancy Merkle,” nobody has ever come forward to take credit and the article contains no citations (source: Guthrie).
The FDA Center for Drug Evaluation and Research refuted the claims made in the account, which linked aspartame to a number of diseases and maladies, including MS. According to the FDA, aspartame is one of the most frequently tested food additives and there’s no evidence to support a link between aspartame and MS (source: Hattan). That’s good news for Nancy and others who drink diet beverages and opt for “low-cal” foods containing aspartame.
In December 1966, the body of 92-year-old Dr. J. Irving Bentley was discovered in his Pennsylvania home by a meter reader. Actually, only part of Dr. Bentley’s leg and slippered foot were found. The rest of his body had been burned to ashes. A hole in the bathroom floor was the only evidence of the fire that had killed him; the rest of the house remained perfectly intact.
How could a man catch fire — with no apparent source of a spark or flame — and then burn so completely without igniting anything around him? Dr. Bentley’s case and several hundred others like it have been labeled “spontaneous human combustion” (SHC). Although he and other victims of the phenomenon burned almost completely, their surroundings, and even sometimes their clothes, remained virtually untouched.
Can humans spontaneously burst into flames? A lot of people think spontaneous human combustion is a real occurrence, but most scientists aren’t convinced.
In this article, we will look at the strange phenomenon of spontaneous human combustion, see what believers have to say about it and try to separate the scientific truth from the myths.
What is Spontaneous Human Combustion?
Spontaneous combustion occurs when an object — in the case of spontaneous human combustion, a person — bursts into flame from a chemical reaction within, apparently without being ignited by an external heat source.
The first known account of spontaneous human combustion came from the Danish anatomist Thomas Bartholin in 1663, who described how a woman in Paris “went up in ashes and smoke” while she was sleeping. The straw mattress on which she slept was unmarred by the fire. In 1673, a Frenchman named Jonas Dupont published a collection of spontaneous combustion cases in his work “De Incendiis Corporis Humani Spontaneis.”
The hundreds of spontaneous human combustion accounts since that time have followed a similar pattern: The victim is almost completely consumed, usually inside his or her home. Coroners at the scene have sometimes noted a sweet, smoky smell in the room where the incident occurred.
What makes the charred bodies in the photos of spontaneous human combustion so peculiar is that the extremities often remain intact. Although the torso and head are charred beyond recognition, the hands, feet, and/or part of the legs may be unburned. Also, the room around the person shows little or no signs of a fire, aside from a greasy residue that is sometimes left on furniture and walls. In rare cases, the internal organs of a victim remain untouched while the outside of the body is charred.
Not all spontaneous human combustion victims simply burst into flames. Some develop strange burns on their body which have no obvious source, or emanate smoke from their body when no fire is present. And not every person who has caught fire has died — a small percentage of people have actually survived what has been called their spontaneous combustion.
