UFO: a knowledge problem






For those of us who have lived the whole cycle of the UFO phenomenon, I highly recommend "The UFO phenomenon" a book by John Greer, "The Archdruid". The book is also summarized in a post of his.

Greer is a lucid thinker, an excellent analyst, and his knowledge is truly encyclopedic. The result is a book that, as it could have been expected (and as he himself describes) "managed the not inconsiderable feat of offending both sides of the UFO controversy. It did so by the simple expedient of setting aside the folk mythology that’s been heaped up with equal enthusiasm by true believers in extraterrestrial visitation and true believers in today’s fashionable pseudoskeptical debunkery."

It is not often that a book can change one's worldview, but this one did that for me on several points. Greer is completely right in noting that the UFO phenomenon - as others - have given rise to a wave of "pseudoskeptical debunkery." The concept is that often scientifically minded people have gone too far in their criticism of anything that appears to be outside what we consider the realms of science.

One of the problems considered by Greer is disinformation, that is the willful distortion and misrepresentation of the data. It is something that plays an important role every time we move away from phenomena which can be comfortably reproduced in a laboratory. But scientists have usually no training and no experience in recognizing disinformation and dealing with it. They just tend to ignore it, and are easy victims of its effects. On this point, the discussion in Greer's book is excellent and brings overwhelming support to his conclusion that the UFO phenomenon is mainly the result of disinformation created by the US military.

Another point raised by Greer is how the debate on UFOs has been framed using different views on how to obtain knowledge (if you like, it is an epistemological problem). Believers in the extraterrestrial origins of UFO have been using rhetorical methods, debunkers have been using the scientific method. Greer correctly notes that there is an abyss of difference in the two methods. Science tries to verify a theory by falsifying it and just one experiment that goes against the theory will destroy it. Rhetoric attempts to buttress a theory by piling up positive results and neglecting negative ones. When we get to debating UFOs, debunkers are at a definite disadvantage as they have to prove that all sightings are illusions, or hoaxes, or known flying objects. It can't work.

So, if someone says that he has seen strange lights in the sky, it is silly to feel that a scientist's duty is to automatically dismiss that by saying that it was just the planet Venus or something like that. That doesn't mean that we have to cede to the tsunami of pseudoscience diffusing all over the infosphere, but science will lose credibility if it continues operating in the "automatic debunking mode". (See, for instance, this post by Paula). And if science loses credibility, it will become more and more difficult to demolish even clearly flawed claims, for  instance about low temperature nuclear fusion.

The epistemological problems that Greer raises is profound and important. Suppose that there existed alien intelligences, and that it were possible to contact them, would the scientific method be suitable to study them? Hardly so, at least beyond a trivial level. Even studying the behavior of our own species - which we know to exist - turns out to be extremely difficult and easily affected by disinformation campaigns, as it has happened to "The Limits to Growth" study in 1972 and is happening now for climate science.

Modern science was born to study the motion of planets and to solve all kinds of mechanical problems. But, in time, we have been discovering how complex the universe is. Think just about this: we have good models telling us how human activity is changing the climate. But we have no good models telling us how to convince humankind that it is crucial to stop doing the things that create climate change. Clearly, we are missing something and something very important, which the scientific method can hardly deal with. The story of the UFO phenomenon is a reminder that we need - as always - to go beyond the old paradigms.

  1. You've made a good point about the debunking mode. The "skeptic" attitude found all over the Internet comes with a lot of condescension and sarcasm. This also tends to encourage an attitude of persecution in supporters of alternative theories.

    Greer manages to subvert the expectations of debunkers and believers alike by looking at the impact of UFOs on our culture. Perhaps someone might do this for peak oil and climate change in a few decades -- I expect we will see they have had positive impacts. But UFO stories seem to be confused regurgitation of more traditional types of otherworldly experience. I like his observation that UFO abduction experiences frequently resemble descriptions of initiation experiences in shamanism.

  2. I share Ugo's concern for science having a non constructive approach to the phenomenon.
    On the other side Greer writes like the typical debunker:
    "Move out of the realm of testimony and look for physical evidence, and the trail becomes much thinner. A few marks on the ground that might have been produced by UFO landing gear have been found and photographed. A few scraps of metal and other substances that might have come from flying saucers have been obtained and tested, though none has shown any particular trace of an unusual origin. A modest collection of photographs has been amassed, though most of them have failed tests of authenticity and the remainder yield little information. An equally modest collection of supposed government documents have surfaced, none of them particularly convincing and most of them self-evident hoaxes."
    The UFO Phenomenon

    He is inviting to not further look in the phenomenon. Who does it is disillusioned:
    "For believers in UFO conspiracy theories, the supposed presence of the aliens also offers that very human comfort in difficult times, a scapegoat that can be blamed for the failure of a belief system to conform to reality.
    The UFO Phenomenon"

    The main cultural aspect is not even discussed in the book:
    The chart published in the prev article (http://4.bp.blogspot.com/-wiYVvrv5MG4/U_iK965u5XI/AAAAAAAAMXU/JudF7oIg3LQ/s1600/UFO.JPG) shows clearly that scientists have stopped actively deal with the phenomenon in the early 70's The period coincides with the publication of the Condon Report, which concluded that UFOs were a non-phenomenon. Shortly after the project Blue Book was officially closed and the American forces stopped working on it. From that moment on, anyone who has dealt with the phenomenon has been subjected to ridicule. There is no wonder that scientists care about their career will be kept out of the theme.
