spontaneous human combustion 1122News reports of a recent death by fire in Tulsa, OK read, “Sheriff: Oklahoma Man Died of Spontaneous Human Combustion,” and “Sheriff Rules Out Homicide, But Not Spontaneous Combustion After Autopsy.”

It’s actually not difficult to rule out spontaneous human combustion (SHC) – you can rule it out because SHC does not exist. The notion of SHC is that some process occurs in the body that causes it to heat to the point of spontaneous ignition, without an external ignition source. There simply is no known process by which this could occur.

This is not a trivial objection. While it is, of course, impossible to completely rule out the unknown, the laws of physics can make something so improbable that we can comfortably treat it as if it were impossible. At the very least the burden of proof should be extremely high – not so high that if the phenomenon were genuine we could not demonstrate it, but high enough to rule out other, even unlikely, causes.

spontaneous human combustion 1123_250pxThe lack of a possible mechanism has inspired some SHC proponents to hypothesize new elementary particles as an explanation. Larry Arnold, in his book, Ablaze, posits the existence of the pyroton to explain the energy source that leads to SHC. He is not a theoretical physicist and is therefore probably not aware that you can’t just make up new particles and insert them into the standard model just to explain your alleged phenomenon. This is a rather extreme example of special pleading.

It is also curious that there are no pre or partial SHC phenomena. No one has heated up to near combustion. We also don’t see alleged cases of SHC in animals – why isn’t there spontaneous pig combustion?

Plausibility aside – what does the empirical evidence say? Are there any compelling cases of SHC, as Sheriff Lockhart seems to believe, saying:

“I think there’s only about 200 cases worldwide, and I’m not saying this happened. I’m just saying that we haven’t ruled it out.”

The hallmark of the SHC claim is that ignition occurs without an external source. It is curious, then, that one fairly consistent feature of alleged SHC cases is the presence of an external ignition source. The typical profile of a victim is an elderly or infirmed individual, or someone taking sedating medication or a heavy alcohol drinker, who lives alone and is also a smoker. Being overweight also is a common feature.

Spontaneous Human Combustion (SHC) is one of those classic pseudosciences that have been around for a long time – like astrology, Big foot, and the Bermuda Triangle. I put it in the same category as the myth that we only use about 10% of our brain capacity; it’s widely believed, but no one really cares that much. It’s just something people hear about and have no reason to doubt, so they lazily accept it. I did when I was younger (in my pre-skeptical days), you hear about it on TV and think, “Huh, isn’t that interesting.”

It’s therefore a good opportunity to teach critical thinking skills. People’s brains are clogged with myths and false information, spread by rumor and the media, and accepted due to a lack of having the proper critical thinking filters in place. It’s disappointing, however, when people who should know better, or whose job it is to know better, fall for such myths.

Recently an Irish coroner concluded that a man died from SHC, and it is reported:

The West Galway coroner, Ciaran McLoughlin, said there was no other adequate explanation for the death of Michael Faherty, 76, also known as Micheal O Fatharta.

and

The coroner said: “This fire was thoroughly investigated and I’m left with the conclusion that this fits into the category of spontaneous human combustion, for which there is no adequate explanation.”

First, let’s play a game of name-that-logical-fallacy. The core fallacy the coroner is committing is the argument from ignorance. The investigation could not find a cause for the fire, therefore here is the specific cause – SHC. The conclusion should rather be – we don’t know what caused the fire.

The coroner said the case “fits into the category” of SHC – but how?

On a recent episode of Fringe (a rather mediocre, in my opinion, series on the supernatural), the investigators come across apparent cases of spontaneous human combustion (SHC).  Popular Mechanics decided to write an article about the science behind SHC (it turns out there isn’t any) and luckily contacted me to give them the skinny. You can read the article here.

SHC is a fun pseudoscience in that there is nothing concrete at stake – no health claims, no products, no concerns about squandering limited research funds. It’s purely a scientific question, one highly amenable to skeptical analysis.

In order to understand SHC imagine the following scene: An elderly woman who lives alone is found dead in her apartment. She is the victim of fire; her body is mostly reduced to ash, and only the ends of her arms and legs remain. The ashen outline of her head lies upon the hearth of her fireplace, the iron grill of which has been knocked to the side. There are signs that a fire recently was burning in the fireplace. A brown greasy substance coats the walls and ceiling near the body, but otherwise the room is unharmed.

Now set aside all common sense and reason, and you’ll have a typical case of spontaneous human combustion.

The idea that people can suddenly and spontaneously burst into flames … (keep reading) NeuroLogica Blog » Spontaneous Human Combustion.
