Copromancy is the art of prognostication based on examining feces. Copromancy has a long history, and is part of traditional Chinese medicine[1] and Ayurveda.[2] These practices should not be confused with the Bristol Stool Scale (used in mainstream healthcare to evaluate constipation, normal stool or diarrhea[3]) nor with evidence-based testing of stool samples (such as checking for parasites, analyzing pancreatic functioning, or to look for malabsorption of nutrients[4]).

Stalinist stool[edit]

According to former Soviet agent Igor Atamanenko, Joseph Stalin set up a special department of the secret police that sought to obtain and analyze feces samples to make psychological portraits.[5] Lavrentiy Beria was allegedly in charge of the department. Atamanenko claimed that the department analyzed Mao Zedong's poo.[5] High levels of tryptophan allegedly indicated that a "person was calm and approachable", whereas low levels of potassium indicated a nervous disposition and insomnia.[5]

Raymond Moody doody[edit]

Raymond MoodyWikipedia advocated woo-based copromancy [6] before he shifted gears to popularize the near-death experience phenomenon[7] and before he obtained a medical degree.

Moody claimed to be scientific:[6]

Without in any way disparaging tea-leaf reading, astrology, palmistry, phrenology, or any of the other similar techniques, we can say with certainty that coprology — with its modern scientific methods of research, controlled experiments, and computer analysis — is able to obtain much more accurate predictions of future life trends than any other known method.

However, Moody then launched into a very unscientific and unsubstantiated methodology of feces analysis based on:[6]

  • shape ("Curve or Priscilla", "Spiral of Raymondus", "Tetterton's Spheroids"…), internal structure, color, hardness, and configuration predicting one's character
  • configuration, acidity, and moisture content predicting one's future
  • nodes, fissures, and micro-organisms predicting one's health

Yes, stool micro-organisms can predict health, but Moody could not have detected the microbial diseases he claimed based on hand-drawn squiggle-like fissure variations that he described.[6] The book reads like it could be one long prankexcept — Moody went on to more quackery by promoting near-death experiences,[7] and except for the other celebrity poo-readers (Gillian McKeith and Deepak Chopra).[2][8] At the time of publication, Moody claimed to be the discoverer of coprology and to hold "Bachelor of Arts, Master of the Arts, Doctor of Philosophy, Doctor of Racial Science, and Doctor of Coprology degrees, and [to have] been a professor of logic and metaphysics". Moody also claimed to be the president of the International Coprological Society and the "Oberleiter of the American Militant Action Party".[6]

Awful poo lady[edit]

The most famous of all modern copromancers however would seem to be The Awful Poo Lady, self-proclaimed nutrition expert Gillian McKeith, who brought copromancy to prime-time television.[8]

Obligatory pun[edit]

As you can see, the concept is a load of crap. There, we said it.
