Marcello Truzzi

From Wikipedia, the free encyclopedia

Marcello Truzzi

Marcello Truzzi (September 6, 1935-February 2, 2003) was a professor of sociology at Eastern Michigan University, founding co-chairman of Committee for the Scientific Investigation of Claims of the Paranormal, a founder of the Society for Scientific Exploration, and director for the Center for Scientific Anomalies Research. ^[1]

Truzzi was an investigator of various protosciences and pseudosciences and, as fellow CSICOP cofounder Paul Kurtz dubbed him, "the skeptic's skeptic." He is credited with originating the oft-used phrase "Extraordinary claims require extraordinary proof," which Carl Sagan then popularized as "Extraordinary claims require extraordinary evidence." ^[2] However, this is a rewording of the Principle of Laplace (see Pierre Simon Laplace#Quotes) which says, "The weight of evidence for an extraordinary claim must be proportioned to its strangeness." ^[3] This, in turn, may have been based on the statement "A wise man, therefore, proportions his belief to the evidence" by David Hume^[4].

[edit] Biography

Zetetic Scholar journal founded by Marcello Truzzi

Truzzi was born in Copenhagen, Denmark. His family, a group of circus performers, moved to the United States in 1944. His father, Massimiliano Truzzi, was an outstanding juggler. Truzzi served in the United States Army between 1958 and 1960. He became a naturalized citizen in 1961.

Truzzi founded the skeptical journal Explorations and was invited to be a founding member of the skeptic organization CSICOP. Truzzi's journal became the official journal of CSICOP and was renamed The Zetetic, still under his editorship. About a year later, he left CSICOP after receiving a vote of no confidence from the group's Executive Council. Truzzi wanted to include pro-paranormal people in the organization and pro-paranormal research in the journal, but CSICOP felt that there were already enough organizations and journals dedicated to the paranormal. Kendrick Frazier became the editor of CSICOP's journal and the name was changed to Skeptical Inquirer.

After leaving CSICOP, Truzzi started another journal, the Zetetic Scholar. He popularized the term Zeteticism as an alternative to Skepticism, because the term Skepticism, he thought, was being usurped by what he termed "pseudoskeptics". A zetetic is a "skeptical seeker." The term's origins lie in the word for the followers of the skeptic Pyrrho in ancient Greece and was used by flat-earthers in the 19th century. Truzzi's form of skepticism was Pyrrhonism, as apposed to the Academic tradition founded by Plato, which is followed by most scientific skeptics ^[5].

Truzzi was skeptical of investigators and debunkers who determined the validity of a claim prior to investigation. He accused CSICOP of increasingly unscientific behavior, for which he coined the term pseudoskepticism. Truzzi stated,

"They tend to block honest inquiry, in my opinion. Most of them are not agnostic toward claims of the paranormal; they are out to knock them. [...] When an experiment of the paranormal meets their requirements, then they move the goal posts. Then, if the experiment is reputable, they say it's a mere anomaly."

Truzzi held that CSICOP researchers sometimes also put unreasonable limits on the standards for proof regarding the study of anomalies and the paranormal. Martin Gardner writes: "In recent years he (Truzzi) has become a personal friend of Uri Geller; not that he believes Uri has psychic powers, as I understand it, but he admires Uri for having made a fortune by pretending he is not a magician." ^[6]

Truzzi co-authored a book on psychic detectives entitled The Blue Sense: Psychic Detectives and Crime. It investigated many psychic detectives and found them all to be either self-deceptive or intentionally deceptive. Nevertheless, the authors concluded that there might be some psychic detective out there somewhere with genuine psychic powers. This is said to be typical of Truzzi's approach.

Although he was very familiar with folie a deux, Truzzi was very confident a shared visual hallucination could not be skeptically examined by one of the participators. Thus he categorized it as an anomaly. In 1982 Truzzi exaggerated that controlled ESP (ganzfeld) experiments have "gotten the right results" maybe 60 percent of the time. ^[7] This is yet to occur.

Truzzi died from cancer on February 2, 2003.

"In science, the burden of proof falls upon the claimant; and the more extraordinary a claim, the heavier is the burden of proof demanded. The true skeptic takes an agnostic position, one that says the claim is not proved rather than disproved. He asserts that the claimant has not borne the burden of proof and that science must continue to build its cognitive map of reality without incorporating the extraordinary claim as a new "fact." Since the true skeptic does not assert a claim, he has no burden to prove anything. He just goes on using the established theories of "conventional science" as usual. But if a critic asserts that there is evidence for disproof, that he has a negative hypothesis -- saying, for instance, that a seeming psi result was actually due to an artifact -- he is making a claim and therefore also has to bear a burden of proof."
