De la contagiosité de l’électrohypersensibilité

Abstract

Electro-hypersensitivity (EHS) is a phenomenon that emerged in the 1980s and which seems to attribute the occurrence of some symptoms to an exposure to electromagnetic fields (EMF). Since it has appeared, the number of cases has not stopped increasing, suggesting some kind of contagion. However, the correlation between exposure and the onset of symptoms has been tested repeatedly and has never been confirmed. The hypothesis that a psychogenic effect named the “nocebo effect” could be at work then took shape, bringing us to an awareness of our ever-increasing exposure to anxiety-inducing news about the presence of EMFs. This context of negative expectations reinforces the action of the nocebo effect (an effect which is inherently contagious) but does not, in itself, explain the path of a majority of victims in whom the onset of symptoms preceded knowledge of a possible harmful effect of EMFs. Different studies have shown that in the latter case, it could be a phenomenon of wrong attribution of symptoms. The victims, left unanswered by the medical community, will seek a cause and will be confronted with the orientation of the cognitive market towards EMF. This confrontation will be all the more unbalanced as the victim is unaware that it is subject to many cognitive biases in its way of understanding the information offered to it. Once the attribution is established, the nocebo effect can again come into play and strengthen the feeling of being a victim of EHS. Whatever the path, the victim enters a vicious circle from which it appears very complicated to escape.
