Марчелло Труцци: Америкалық социолог және зерттеуші ғалым

American sociologist (1935–2003)

Marcello Truzzi (September 6, 1935 – February 2, 2003) was an American sociologist and academic who was professor of sociology at New College of Florida and later at Eastern Michigan University, founding co chairman of the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP), a founder of the Society for Scientific Exploration, and director for the Center for Scientific Anomalies Research. 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", though earlier versions existed.

Truzzi was born in Copenhagen, Denmark, and was the only child of juggler Massimiliano Truzzi and his wife Sonya. His family moved to the United States in 1940 where his father performed with the Ringling Bros. and Barnum & Bailey Circus. Truzzi earned several degrees in sociology: his Bachelor of Arts from Florida State University in 1957, his Master of Arts from the University of Florida in 1962, and his doctorate from Cornell University in 1970. He served in the United States Army between 1958 and 1960; he became a naturalized citizen in 1961.

A professor of sociology at Eastern Michigan University from 1974–2003, He promoted the term "zeteticism" as an alternative to "skepticism", because he thought that the latter term 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. Skeptic's Dictionary memorialized Truzzi thus:Truzzi considered most skeptics to be pseudoskeptics, a term he coined to describe those who assume an occult or paranormal claim is false without bothering to investigate it. A kind way to state these differences might be to say that Marcello belonged to the Pyrrhonian tradition, most of the rest of us belong to the Academic skeptical tradition. 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 wrote: "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." Truzzi co authored a book on psychic detectives entitled The Blue Sense: Psychic Detectives and Crime. It investigated many psychic detectives and concluded: "[W]e unearthed new evidence supporting both sides in the controversy. We hope to have shown that much of the debate has been extremely simplistic." The book also stated that the evidence didn't meet the burden of proof demanded for such an extraordinary claim. Although he was familiar with folie à deux, Truzzi was confident a shared visual hallucination could not be skeptically examined by one of the participators. Thus he categorized it as an anomaly. In a 1982 interview Truzzi stated that controlled ESP (ganzfeld) experiments had "gotten the right results" maybe 60 percent of the time. This question remains controversial. Truzzi remained an advisor to IRVA, the International Remote Viewing Association, from its founding meeting until his death. Truzzi was Keynote Speaker at the 1st annual National Roller Coaster Conference, "CoasterMania", held at Cedar Point Amusement Park, Sandusky, Ohio, in 1978. On the subject of riding in the front vs riding in the back of a roller coaster, he said:
sign=|source=|The front of the roller coaster is really less stressful than the back part of the roller coaster. The first time you're worried about a roller coaster, you might be better off riding in the front, because you're not at the tail end of the whip. The average fellow getting on a roller coaster (thinks), "Oh boy, the most dangerous place must be the front, because you're right there, nobody in front of you to tell you how to act, and so on; it must be the worst place, so I'm going to get in the 'safe' part in the back." Because that's what we do: we get in the back of busses, we get in the back of planes, and so on. We figure that’s the safe part. Well, there's a certain irony here, because the guy who says, "I'm gonna prove how macho I am, I'm gonna to really conquer my fear, I'm gonna get in the toughest place", and he gets in front. When he finishes the ride, he must feel like, "Gee, it wasn't so bad, after all." Whereas that poor milquetoast fellow who gets in the back, he's probably never going to ride again. So one of the things you might predict is that people who ride in the front of roller coasters are more likely to ride again. People who ride in the back for the first time are less likely to bother to go on it again. Truzzi died from cancer on February 2, 2003.

Truzzi's remark is derived from the 18th century French mathematician Pierre Simon de Laplace's "plus un fait est extraordinaire, plus il a besoin d'être appuyé de fortes preuves" (the more extraordinary a fact is, the more it needs to be supported by strong evidence). Carl Sagan later popularized Truzzi's adaptation of Laplace as "Extraordinary claims require extraordinary evidence", which came to be known as the Sagan standard.

In 2017, World Scientific released a book edited by Dana Richards about the correspondence between Martin Gardner and Truzzi. The book called Dear Martin, Dear Marcello: Gardner and Truzzi on Skepticism is broken up into four sections; "The Road to CSICOP", "The Demarcation Problem", "The Dissolution", and the "Return to Cordiality". The early letters from Truzzi were not preserved and the beginning of the book seems one sided with only Gardner's letters. The editor, Richards states in the introduction the conflicts between the two men, their differing goals for CSICOP, and various people in the skeptic and paranormal communities. They discuss many topics including publishers, Geller, and the "definitions of charlatan and crankpot".
