"Over the past few years a growing number of French ufologists have become increasingly doubtful about the existence of UFOs as a genuinely original physical phenomenon. I should like to analyse briefly the origins and limits of this doubt.
The first French ufologist to have said “the emperor has no clothes” was Michel Monnerie, in two hotly debated books. [1] He was until then a very classical ufologist, and a member of the editorial
board of Lumieres dans la Nuit, the leading UFO magazine in France, from which post he was fired after publication of his second book. Monnerie’s reasons for doubting can be Summarized in two main arguments:1. The non-specificity of the residue of unexplained cases – in other words the lack of distinction between explained and unexplained cases: exactly the same patterns and the same characteristics appear in both sets of cases. Indeed, cases with typical UFO effects have been explained: electro-magnetic effects, landing traces, humanoids, effects on animals, physiological effects, etc. I personally have investigated with friends a case which involved two witnesses, a burnt trace in a field and a howling dog – it was the rising moon: The unexplained cases have no unique peculiarities.2. The continuity between the trivial and the extraordinary: for any phenomenon it is possible to define a set of median, or most probable characteristics (for size, colour, speed, etc.). But all these parameters are distributed about the median, and sometimes the appearance of a phenomenon is very far from the median, because of the inherent variability of the phenomenon, because of had sighting conditions or misrepresentation by the witness. It follows that the further the characteristics are from the median, the less will people be able to recognise the true nature of the phenomenon. For Monnerie, UFOs are situated at the ends of the distribution function, at the ends of a bell-shaped curve. They are thus ‘fringe phenomena’ of a larger set of phenomena, but their peripheral location is not perceived as such because ufologists remove the more central part of the curve, where the less strange phenomena are identified by the witnesses themselves or by the field investigators. Ufologists, Monnnerie says, arbitrarily call the minor misinterpretations ‘false UFOs’ and the major ones ‘true UFOs’, and do not realise that there is a perfect continuity between the two series, and that the difference between them is of degree not of nature."KEEP ON READING THIS FUNDAMENTAL ARTICLE.
