‘ALTERNATIVE’ APPROACHES TO THE STUDY
|Circumscribed rationality||Powerful rationality|
|Widespread in the occultist tradition and its parascientific offshoots, but seen also in the approach adopted by many researchers (p. 383). It is actually found as much [among] ordinary people as [among] scientists who display poor reasoning power. The so-called institutional criterion alone (a good level of rationality is that which is to be found among qualified scientists) therefore proves insufficient.||This rare form of rationality is mastered by some scientists and reveals its qualities through the practical achievements to which science has contributed (p. 383).|
|The everyday world, where it is sometimes necessary to make decisions according to hypotheses based on approximated evidence, and which may even be partially false, but which do not mislead us unduly, while giving us a sufficient grasp of reality to avoid certain lethal dangers and satisfy several elementary needs (p. 392).||It would only be in an ideal and unfortunately non-existent world in which the life of society would be based on tested knowledge that powerful rationality could become an absolute and inviolable value. Thus, it is sometimes rational [to] abandon cognitive effectiveness in favour of social effectiveness (p. 391)|
|Intellectual approach||Axiomatic – a method adopted long ago by those other parascientifics, the theologians: “Without demonstration or evidence’ certain ‘postulates’ are admitted as ‘axioms’ and become ‘articles of faith which serve as a starting-point for deducing other theses, which therefore deserve to be called ‘theorems’. Produced in great quantity, the theorems are then used to interpret objects, explain events, reconstruct the past, predict the future and judge the present.” (p. 323)||Scientific, i.e. operating in accordance with a process of moving backwards and forwards between observed facts and theoretical assumptions.|
|Because of a ‘basic incomprehension of the way in which knowledge is elaborated’, these are seen as resulting from an ‘accumulation of observed data gathered independently of any hypothesis’ or as ‘simple opinions that each person chooses arbitrarily, according to his or her predilections or whims, and which no argument could influence’ (p. 384).||It ‘accords equal importance to observed data and to speculative conjectures, but the former intrigue him insofar as they resist or agree with the latter, and the latter are of concern to him insofar as they can be used to test the former’ (p. 385).|
|It is ‘subjugated to non-negotiable principles, which one refuses to give up whatever the cost’ (p. 386): ‘This certainty establishes a conceptual space within which various concurrent hypotheses can be generated which are susceptible to debate but which should not be opposed to the initial postulate’ (p. 303).||‘Explanatory ideas are above all conjectures intended more for critical examination than for admiration and enthusiastic contemplation.’ (p. 386)|
|It places ‘excessive trust in intuition [its ‘first criterion of epistemological evaluation’], while thus increasing the risk of remaining a prisoner of commonplaces’.||It ‘prefers to judge ideas in the light of their conformity to observed data’ (p. 387).|
|It is polarised ‘on the search for confirmations’, which represents its favorite method of validating hypotheses, while at the same time there is no idea ‘so aberrant that it cannot find at least some facts that seem to support it’. Observed data can even be invented intentionally to help confirm the starting-axioms.||It “shows an equal interest in inconvenient facts and ‘confirmations’” and “favours ideas to which the observation of reality awards the maximum number of votes in favour and the minimum number of unfavourable testimonies” (p. 388).|
|It “takes good care not to take any notice of ideas that compete against its preferred theses” (p. 389).||“In this approach one not only tests ideas against reality but also compares them at the same time with other ideas.” (p. 389)|
|Factual evidence is used “as a secondary illustration of the validity of the theorems derived from the axioms, and not as a means of testing those axioms” (p. 324); for this reason, those adhering to these views can at one and the same time “be relaxed about the multiplication of ‘evidence’” and “willing to give up” those deficiencies in their theories to which their attention has been drawn (pp. 287-288).||“Adhesion to a theory is related to the preliminary acceptance of the evidence.” (p. 58)|
|Examples||“Theosophy, Ancient Astronaut theory, Jungian analysis, Eliade's approach to the history of religions, or the Monism of Haeckel.”||“The occultists ramble on about nuclear weapons, warn us against vaccines, speculate about the possible uses of cloning, or reinterpret the theory of the Big Bang, but they themselves did not discover nuclear weapons, vaccines, cloning or the theory of the Big Bang.” (p. 382)|
Contemporary pseudohistorians adhere to practices that are similar to those of the Romantic school of historiography, i.e. practices that were current before the rules defined by the ‘methodical school’ of historiography were imposed. In addition to their penchant for the Middle Ages and the Merovingians they also have in common the fact that, to compensate for the deafening silence of their sources, they readily assign a ‘place to intuition and imagination when they are not actually in an hallucinatory trance’, use and abuse ‘metaphors to transmute by the magical power of words an analogy into a proof’ , adopt processes of dramatisation from Romantic technique and, all in all, take as their motto that of Prosper de Barante (1782-1866), taken from Quintilien: Scribitur ad narrandum non ad probandum (‘You write history to tell a story, not to prove things’).
Georges Bertin, who holds a doctorate in social sciences and is affiliated with the Centre de recherches sur l'Imaginaire in Angers, and who notably is the author of La Quête du Saint Graal et l'Imaginaire (1997), attended conferences on the Rennes-les-Château affair in the summer of 2005 which illustrate quite well some of the faults that we have just discussed. The Rennies behind the conferences were introduced as follows: Jean Sinet was described as the ‘president of a local research association currently being established in Paris’ while admitting that ‘he was using an assumed name, for security reasons’ (!), Christian Doumergue was described as an ‘archivist’, ‘without us being told what vantage-point he was speaking from or what his institutional affiliation [and] scientific training were’, while Pierre Jarnac, alias Michel Valet, had the title of ‘historian’ bestowed on him even though he does not have a relevant degree. The first two speakers defended a relationship between Jesus Christ and Mary Magdalene which fed upon, in fine detail, ‘an imaginary scenario of blood and race and/or a supposedly pure Arianist religion establishing the line of French sovereigns of the Ancien Régime as a ‘sacred race’, and argued that their work, ‘thanks to the discovery of the treasures of the Razès', [would help] ‘restore Christianity to its original purity’.
As for the conference that was organised a short time afterwards by the same Monsieur ‘Sinet’ assisted by Monsieur ‘Jarnac’, this was ‘a dazzling dispay of historical, theological and epistemological approximations, consacrating a purely imaginary scenario disconnected from all the developments proven to have taken place in the social reality of the historical period under consideration’. The fact that The Da Vinci Code, to which the conference was partly devoted, is, ‘only a detective story’  was never taken into account. In particular, no ‘literary, historical or ideological analysis’ of Dan Brown's sources was suggested, whereas ‘when dealing with documents of any kind you must always first submit them to internal and external criticism – but, of course, methodology is hardly the strong point of our two authors’.
The speakers then started to discuss the Rennes affair itself, sustaining ‘a unidirectional discourse which was actually sightly paranoid, the whole thing being based, as regards form, on carefully-phrased remarks of the type ‘if one accepts the assumption...’, ‘we can assume that...’ or ‘probably..’ and accumulating ‘many historical untruths which were presented as if they were axiomatic’. Their talks were larded with lapidary statements ‘without any signs of any scriptural, archaeological or linguistic evidence’, with interpretations, taken completely out of context, of various material artefacts, such as ‘this fresco from Vaux-le-Vicomte who shows a mountain (therefore for our authors obviously the Pyrenees), a cave (i.e. that of Bugarach) and a fountain (to be chosen from the numerous sources of waters to be found in the region)’, without ‘any questioning of the conditions under which the work was produced, those of its reception, the intentions of its creator within its artistic context’, and with various anachronisms, such as turning the Freemasons into ‘compilers of rebuses’, whereas ‘speculative Freemasonry only made its appearance almost a century after the events in question’, all the while being sublimely ignorant of or deliberately concealing the ‘works of genuine historians’, who for example ‘abandoned the Arianist links of the Cathars more than 20 years ago for perfectly valid reasons’… 
To sum up, the general procedure for the construction of these pseudoscientific edifices seems to follow three stages:
- An individual – ‘a bad’ scientist, a self-proclaimed researcher, an ‘ordinary Joe’ confronted with a phenomenon which he cannot explain, or an inveterate liar guided by his own reasoning… starts by making a ‘monstrous’ induction, i.e. he builds a whole thesis on just one case, a simple clue, a mistake in interpretation, or a forgery… He privileges analogical reasoning, i.e. thinking via the association of ideas, over analytical reasoning. Preconceived ideas are intuitively connected to elements that are taken out of context. An ‘enigma’ is thus invented. As long as the ‘discoverer’ has some small talent for writing or for setting the scene, or is able to use the services of a third party to do that for him, the central thesis will appear plausible in the eyes of non-specialists. After all, when one does not have all the data to hand it is certainly not always a simple matter to distinguish between truth and falsehood.
- To the extent that this initial postulate – attractive but not proven – forms a solid support for the imaginary scenario it leads to a cascade of all kinds of analogies and deductions and to all kinds of gratuitous speculations being offered as so many ‘lines of enquiry’ by the small knot of authors who are determined to get the ‘extraordinary’ accepted as fact. The initial inductive process has established a framework by offering a multiplicity of combinative possibilities, the exploitation of which by those whom Stoczkowski calls the incarnateurs (the ‘embodiers’) gives rise to various alternative theories.
- These derivative speculations alone are then discussed ad nauseam within the community of ‘members’ which has been formed, while the basic induction, which has now become an axiom, is shielded from any real investigation . The criticisms enunciated within this circle are not intended to dispel the ‘mystery’ but, on the contrary, to sustain it as far as possible by constantly relaunching the narrative in new directions, connecting it incessantly with other topics, providing new testimonies etc. Such pseudoresearchers can therefore accumulate, with the passing of the years, an enormous mass of information on their favourite subject without ever drawing any logical conclusions from them. Among these ‘members’ are also to be found the simply inquisitive, people who reason perfectly correctly but who start from false premises, as right from the outset they have had no access to sound information.
In our view, we have identified a basic distinction: unlike the scientist – professional or amateur – who genuinely wants to know, a pseudoscientist has a greater psychological need for a lasting mystery than for an explanation, which in any case will not generally correspond to his expectations. The scientist therefore seems to be motivated by finding an answer to his questions, while the pseudoscientist keeps the question or questions permanently on the boil so that he can continue to produce an endless stream of rich inferences. 
The pseudoscientific approach is therefore unscientific, but nor is it strictly philosophical. In the ultimate analysis it is ‘gnostic’, as the philologist and specialist in Gnostic literature Jean-Pierre Mahé emphasises: “Philosophy at root does not seek to preserve mystery [...], it seeks to explain it, while for the Gnostics it was not a matter of dispelling mystery but of interiorising it. And to interiorise the mystery you must first adhere to the mythical discourse. That is the essence of Gnostic discourse. [...] Myth, in appearance, is a cosmic projection of interior states, but it is deployed in the opposite direction: [...] you start with this cosmic projection and you then explore the depths of your consciousness, and that is precisely why it is important that, on each occasion, new echoes, new resonances, are discovered.” 
The hard core of pseudohistorians, para-archeologists, ufologists and other parapsychologists are therefore the Gnostics of our age.
7. Some major pseudohistorical axioms
“[...] There is a big difference between the act of identifying conspiracies in history and the act of considering that history is, in reality, just a conspiracy.”
Richard Hofstadter (The Age of Reform, Random House, 1955)
“Chance is generally an unwanted guest in human thought and one that, in particular, is inadmissible when confronted with misfortune or tragedy – and conspiracy theories are, above all, a denial of the existence of chance.”
Gerald Bronner (Nos représentations du hazard, Vuibert, 2008)
The speculations that are born and reborn each year on the nature of the ‘secrets’ surrounding Rennes-le-Château naturally fall within a field of study that is delimited by the great axioms of the mythological history. The meme of the Golden Age is found within traditional mythology (variations on the theme of a Lost Paradise are numerous) and during the modern period it is found within various political myths in the form of references to the purity of human origins and to ideas of brotherhood as values that have been polluted by historical evolution. Among ‘alternative’ historians and archaeologists this Golden Age is generally symbolised by an extraordinarily brilliant civilisation that has since disappeared (e.g. Atlantis, Mu, etc.). This is sometimes seen as being extraterrestrial in origin, and one from which ancient ‘known’ civilizations, e.g. the Sumerian, Egyptian, etc. are derived. In ‘Rennology’ the attempts to highlight a sacred geography via remarkable alignments of sites which have formed, since prehistoric times, vast geometrical figures with a mystical connotation around ‘the vaulted hill’, such as the pentacle, have also played their part in this quest for a primordial human harmony.
Belief in a supernatural plan to save humanity is an especially fertile scheme for explaining the course of history. In Christian mythology history is clearly oriented, with a beginning (Creation), an end (Last Judgment) and a path between the two which is illuminated and supervised by a God Who intervenes directly via miracles or indirectly via ‘providential’ human beings. From St. Augustine (City of God, 415-427) to Bossuet (Discours sur l'histoire universelle, 1681), this historical providentialism has dominated the West almost without challenge and has continued to do so until our own times. The theme of the Lost King, the Grand Monarque, as prophesied by Nostradamus, and introduced into the history of Rennes via the Priory of Sion, fits into this framework.
Conspiracies, for their part, occupy a privileged place in the contemporary world as a form of ‘lay’ social explanation. They seem to be the new engine of the mythological school of human history. They also give an illusion of understanding everything at a single stroke and providing some sort of meaning in random events, something that offers a certain psychological satisfaction.
The Rennies in particular have used this key idea as the basis for their inferences. The decipherment of complex ‘enigmas’ is deemed to lead to the revelation of ‘secrets’ capable of calling into question the ‘official’ version of the history of our civilisation. Their speculations initially focused on a political conspiracy – in particular, a dynastic usurpation to the detriment of the Merovingian line – before the Anglo-Saxon authors reoriented themselves towards a plot by the Catholic Church aimed at hiding from the Faithful the true nature of Christ, His true destiny, etc. Unsurprisingly, the revelation of the fraudulence of the Priory of Sion, far from putting an end to the conspiracy theories, has, on the contrary, opened up the way for yet another conspiracy designed to lead researchers astray. The current trend is to visualise a secret or at least discreet society hiding behind Saunière, who financed it with some obscure aim in mind, the majority of authors no longer being able to ignore the fact that his financial resources derived primarily from a frightfully prosaic traffic in mass-fees (see Chapter 14).
A conspiracy theory is defined as “an explanation of an event, a succession of events, or even of the whole or part of the history of a country or the world which relies on the dissembled, coordinated and malevolent actions of a restricted number of people (the ‘conspiracy’), whereas historical studies propose other explanations” . Four great principles provide this type of belief with some structure: nothing happens by accident; everything that happens is the result of hidden intentions or desires; nothing is what it appears to be; and everything is interdependent, but in a hidden way. 
In France, the Revolution of 1789 – the founding-event of political modernity – formed the ideal framework for the spread of such theories (a ‘Masonic conspiracy’, ‘a plot by the Bavarian Illuminati’, etc.). The topics on which contemporary pseudohistorians focus are characterised simultaneously by their predisposition to develop conspiracy theories and by their politico-religious dimension. The arrest and trial of the Templars or the Albigensian Crusade are fertile soil from this point of view. In their tragic destiny the Templars and the Cathars do indeed seem to have been just the playthings of the ‘cold monsters’ of the Church and State. The conspiracy theme therefore opens up a very rich field of possible inferences, all the more so as it has an interface with religious concepts, which have the ability to trigger within our brains systems of inferences “that control our most intense emotions, model our interactions with our peer-group, give us a sense of values, and help us to organise social groups” , all things that, in Levi-Strauss's phrase, are bons-à-penser (‘things that are good to think with’).
Until a short while ago we were restricted to simply noting the existence of this tendency of the human spirit to spontaneously privilege the hypothesis of a ‘hidden hand’ to explain salient events. However, a series of experiments recently carried out by two American psychologists  has made it possible to better understand the circumstances in which people preferentally adopt conspiracy theories. Jennifer Whitson, of the University of Texas at Austin, and Adam Galinsky, of Northwestern University in Evanston, Illinois, have shown that when people are placed in a situation of loss of control they display an increasing propensity to see structures, patterns, links or trends where none exist. They detect coherent and significant relationships in a collection of stimuli that are without interrelationship. They also tend to imagine (actually non-existent) causal relationships between various actions and subsequent events, and suspect that conspiracies are lurking behind ambiguous narratives, etc.
The absence of any control over the events triggers a spontaneous need for order (even an imaginary one) in order to minimise the degree of uncertainty. Controlling and organising the resources of one's environment so that they facilitate one’s survival and procreation are the fundamental motivations behind human behaviour and the basis of what we call politics. The fact of seeing an organised will behind a specific event, whatever it may be, restores a form of comprehension of one's environment and the hope of rediscovering a certain power of intervention and control. Superstitions and protective rituals meet the same needs.
If each and everyone, in certain circumstances, can therefore be led to adopt such a mode of behaviour then there must be other (non-pathological) subjects who are biologically predisposed to it by virtue of their personal ‘cocktail’ of neurotransmitters. Peter Brugger, a neuropsychologist at Zurich University Hospital in Switzerland, has actually shown that significant levels in the brain of one such neurotransmitter, dopamine, affects the propensity to find significance in events which for other people are mere coincidences, and to identify pertinent elements or sequences where none exist. 
Current research in the neurosciences suggests that a ‘paranoid’ vision of the world and an attraction to certain types of beliefs are two facets of the same phenomenon. They seem in any case to offer the most promising line of enquiry for a better understanding of the beliefs of occultists and conspiracy-theorists.
8. The role of human testimony in the pseudosciences
“We know relatively little, in the final analysis, about Bérenger Saunière. Indeed, in the France of the Belle Epoque, a provincial priest was not an especially important figure. There is therefore nothing surprising about the fact that documents describing his actions are quite rare, since first-hand witnesses died a long time ago. In short, to try to understand the priest's complex personality, researchers and journalists the world over have been able to place their faith only in the testimonies of his descendants: of Saunière and his contemporaries there remains only that what their children can remember.”
Yves Lignon (Les Enigmes de l'Etrange, First, 2005)
Noël Corbu (1912-1968) drew abundantly on oral sources to ‘invent’ the legend of Rennes-le-Château. Subsequently, investigators of every kind have made massive demands on the memories of the locals, whose knowledge of history rested mainly on family legends. In those days, before mass-tourism and the ravings of the occultists, the villagers’ tongues were readily untied. For the oldest inhabitants, to be reminded of the days of Saunière was also, and especially, to be invited to talk about the days of their first flush of youth.
Local historian René Descadeillas (1909-1986), who began his investigations shortly after the Rennes affair first burst onto the scene, states that the ‘information’ he was able to gather ‘was provided by very different people, some of whom had personally known Abbé Saunière, while others, the majority, could only testify according to statements their parents or forefathers had made’. He then compared the vaious accounts in order to cross-check them . A close reading of his successive texts leaves one somewhat sceptical, especially regarding the crucial point of the alleged discoveries in the church based on multiple testimonies derived from recollections a long time after the fact.
After the stonemasons, former child-members of the choir and other foster-sisters of Saunière's maid , all of whom were allegedly actors in or witnesses of these discoveries (see chapter 15), the Rennies garnered contributions from various occupational groups: ‘The oral tradition within the social circle of generations of grave-diggers in Rennes-le-Château says that somewhere in the cemetery there is a place where you cannot dig more than six feet without the perimeter-wall collapsing. There must be a strange hole in the ground there.’  And the same author, a little later on, writes: ‘Rumour has it that the priest dug more than ten feet down and was sieving the soil all night, with the faithful Marie Dénarnaud holding a torch’ [].
The post-office on the other hand steered their enquiries in a different direction: ‘The post-mistress in Couiza remembered the impressive number of postal-orders that arrived daily’ ; ‘the postman of the time complained about the weight of the mail addressed to the Abbé’ .
The local teachers provided somewhat different information. In 1974, after the broadcast of a Television documentary on the enigmas of Rennes-le-Château, the village-schoolmistress in the second half of the 1920s, then a Mademoiselle Taillau, remembered, according to Pierre Jarnac, that “the villagers of the time were convinced that the Abbé and his maid had taken advantage of being told about an underground passageway connecting the church to the castle. They were convinced that there were many underground chambers which radiated outwards and that each one of these galleries contained treasure. In the village there was no doubt that Saunière and ‘Mademoiselle Marie’ had then found ‘gold coins and objects encrusted with precious stones’. There was even talk of a crown… Popular belief claimed that they had uncovered by digging, starting from the presbytery, the entrance to an ancient burial-ground. These hollows filled with small treasures which the priest came across as he progressed were explained by the vaults that he upset and emptied of their contents.”  Since Marie Dénarnaud with whom she shared the presbytery at that time and other adult villagers had little to say on the subject, the schoolmistress got her information from the children, who reported to her the conversations that they had overheard.
One of her successors in the pre-war period, a Monsieur Guilhem, stated that the former maid had told him: “The villagers will tell you that the priest found a treasure; but that is not true. It was some women who sent him money.” 
New testimonies have continued to emerge until very recently. In 1988, Gérard de Sède recounted the self-styled ‘memoirs’ that were communicated to him in 1971 by a Madame Baron regarding life in the Saunière-Dénarnaud household during the Belle Epoque: “I believe I am one of the last people still living to have known Abbé Saunière and Marie Dénarnaud at all well: I knew them very well because the door of the presbytery was largely open to us; my sister and I felt at home there. Mademoiselle Marie ran the house, while the Abbé, who was very hospitable, was happy to meet all the expenses, and those were considerable I can tell you. I can see the two dogs Faust and Pomponnet now, as well as the two monkeys Capri and Mora, the kitchen-garden, the large terrace, the rabbit-hutches full of lots of rabbits of all kinds, the birds and the fishes, and the orangery where we spent some pleasant moments learning a sentimental song that the Curé taught us about a dying soldier writing a final letter to his fiancée.” 
Ten years on Germain Blanc-Delmas would report in writing (from memory?) some remarks attributed to her late adoptive father, who was a native of Rennes, on the situation in the village about a century before:
“We didn't really have anything to do with what the priest was up to. We had plenty to do in the fields. [...] At the time in question, when I was about 12, I was already working, and when the priest was doing his building work the young people, who were just a little older than me, were mowing, harvesting and generally slaving away. [...] We would get a good view of the priest when he went to wait for Marie, who would return from the factory by going up the road to Estons. [...]
“When Saunière got rich we started to see barouches struggling up the hill, which was difficult to climb because it only had a gravelled surface. We saw men in frock-coats and top hats accompanied by smart ladies all dolled up in their crinolines and sheltering under broad-brimmed hats or parasols. [...] Marie was pretty and along with her foster-sister did not lose much in comparison with all these smart ladies straight out of a fairy-tale. All this made their friends in the village a bit jealous, because it meant they were reduced to ‘walk-on parts’ as it were. But us boys, it didn't worry us at all. [...] We quickly realised that it was all just a fairy-tale which was really none of our business. […]
“The priest was respected and was one of the local notables along with the mayor and the schoolteacher. It was unthinkable, even in the case of a life as busy as his was, to try to understand the how and the wherefore of his activities. Admittedly, when he finally his luck he came into conflict with the municipality because he was trading on his neighbours' toes. [...]” 
We could extend immeasurably the list of such testimonies, which were collected decades after the alleged events occurred. Scientific research has unfortunately shown that human memory is far from being able to form a sort of instantaneous photograph of an initial stimulus. This does not necessarily mean that every old memory is false but, without cross-checking with other sources, it is simply not possible to reliably sort out various items of communicated information.
In a recent book devoted to the famous legend of the crash-landing of a UFO at Roswell Gilles Fernandez, who holds a doctorate in cognitive psychology and is a former lecturer at L'Université René Descartes (Paris V), clearly highlights the biased approach of the ufologists – statements that apply equally to their colleagues, the Rennies:
“Everything adduced derives above all from witness-statements. However, the first disturbing and disconcerting fact is that there are no individual chapters or valid argumentation to address the hypothesis in the light of false memory syndrome and psychosociological contamination either in respect of the first-hand witnesses or the even more delicate subject of the indirect witnesses to the event. The subject is either not tackled at all or just dismissed with a sweep of the hand.”
“For some investigators [...] it seems that human testimony is infallible and non-refutable. This is undoubtedly because witness-statements are often the only foundation for their arguments. For want of anything better human testimony then acquires the status of evidence. This is an annoying and fallacious manoeuvre when considered in the light of what scientific research on memory or even criminology has revealed.” 
In all the parascientific disciplines human testimony – whatever the age and/or exceptional character of the alleged facts – is readily advanced as evidence. Typically, to dispute its reliability is tantamount, for the average parascientist, to insulting the witness in question, to implicitly describing him or her as a liar, as insane, a drunkard or an old fool. That a person who is sincere and has all their mental faculties can be mistaken does not seem possible to them. Consequently, simply to show sincerity seems to be treated as a necessary and sufficient condition for validating the entire content of their testimony. For that purpose there is generally simple recourse to the argument of authority, which involves presenting the witnesses “as being of good faith and being credible by virtue of the simple fact of their profession, their level of education or some other characteristic automatically seen as positive. This psychological bias, which has been well documented in cognitive psychology, produces what are known as ‘halo effects’. This is the tendency that individuals have, when confronted with a human characteristic deemed to be positive [...], to give a more positive account of all or part of the other characteristics of that person, and of their opinions, discourse, statements etc., sometimes even without knowing what they are in advance.” The statements of such witnesses, thus ‘qualified’ for all types of reports, then become factual data.
Moreover, in such micro-environments “the mode of collecting these testimonies is not standardised, but is simply ‘journalistic’ and sometimes deliberately biased. It is thus methodologically fallacious, in the sense that it induces or can induce certain tendencies to create ‘false memories’ by suggestibility as has been demonstrated in experimental psychology. The testimonies produced and the facts that people recount can therefore be explained by a so-called ‘conformity bias’ in memory, retrospection, the inflation of imagination, errors of attribution, etc., something which has also been well documented in the scientific literature.” Such explanations must be given consideration in all cases before making recourse to more elaborate explanations.
In the final analysis, “if these investigators base the majority of their opinions on remembered testimonies then they should logically be interested in the validity of the remembered testimony as considered scientifically, and, at least, should use a standardised data-collection technique in this context such as is found for example in criminology (the ‘cognitive interview’). The serious investigator should address the phenomenon of false memory in general, asking whether this has not occurred in respect of their own witnesses, as would be the case with any witness who tried to remember events going back 30 years or more. Sometimes false memories are found in connection with events going back just one week. This should be sufficient to cause [the investigator] to at least consider the possibility, in order to be able to decide whether to accept or reject this type of counter-argument within the context of the hypothetico-deductive reasoning that leads to his conclusions.” 
Even more than the alleged witnesses of Roswell, those of Rennes-le-Château were questioned on very remote events by interviewers who, consciously or not, acted suggestively and insistently on certain points rather than others. In both cases also these witnesses were questioned at a time when the surrounding culture had already internalised the historical events in question , which might suggest to them that their help was being sought in respect of something extraordinary, and that the investigator had already formed a personal opinion about it, which he could communicate, deliberately or not, to his witness. But suggestion and suggestibility are the principal explanatory factors in false memory syndrome, which is the Achilles' heel of human testimony, accompanied as it is by an inability to produce accurate physical estimates of such things as distance, size, speed, etc.

 According to Anne Brenon, in practice, and in spite of everything, there are within the historical field certain ‘accursed subjects’ which are ‘so mythologised that they put off people with good intentions’. As an historian who specialises in one such subject herself she feels that the simple fact of being interested in these subjects is enough for you to be regarded as ‘somebody not quite serious’ (Radio Suisse Romande, 19 October 2008).

 The scientific approach also implies a preliminary adherence to certain principles, including methodological naturalism, i.e. the idea that no phenomenon can be explained by a supernatural cause, and to the principle of the economy of hypotheses, i.e. the idea that the explanation that involves the fewest ad hoc assumptions should be privileged until evidence to the contrary is adduced.
 Charles-Olivier Carbonell, op. cit., p. 87.
 A point that one can on the other hand legitimately dispute, the exceptional success of the novel owing much to the fact that its author manges to make the reader believe, by fictional means, that he is revealing certain hidden truths.

 The fundamental axiom of ‘Rennology’ is that something extraordinary was (re)discovered at the end of the 19th century in the area of Rennes-le-Château, while that of parapsychology is that psi actually exists, and that of Ufology that the UFO phenomenon is original and irreducible to everyday explanations, etc.
 The human spirit “needs and generally has a way of organising information in order to impart sense to what has been observed and learned. That enables man to go beyond the information collected or, in the jargon of the psychologists, to generate inferences on the basis of the information gathered. It is this which explains the complexity of cultural transmission. Information is not duplicated but inferred, i.e. spontaneously created on the basis of other information.” (Pascal Boyer, op. cit., p. 46)

The distorted memories of real events – the ‘tidying up’ of the cemetery in 1894-1895, when Saunière ‘[...] reorganised, lifted up or pushed everything into a corner’ against the advice of many of the villagers, the discoveries of certain ossuaries in the 1900s, associated with certain items of furniture, including one realised by a friend of Saunière (see chapters 19 and 20) – seem to have been amalgamated here with the imaginary stories of underground passageways surrounding the old castle to produce a single legendary narrative. We can guarantee that each of the intermediaries would have made his or her own small contribution to the finished canvas.

 The oldest testimonies relating to the discovery in the church in Rennes of certain objects (other than the ‘flagstone of the knights’) were collected after the publication of this alleged fact in the press by the owner of the hotel in the village. However, experiments have shown that presenting falsified evidence to subjects can also contribute to the development in them of false autobiographical memories and false beliefs.
