Então existem médiuns "verdadeiros"...??
Não sei se existem médiuns verdadeiros, mas sei que todos os médiuns que apareceram até agora falharam na manifestação de seus fenômenos mediúnicos ou foram flagrados em situações de fraude consciente ou inconsciente. Até o momento, também desconheço um estudo científico que nega ou afirma categoricamente a existência da mediunidade.
Veja por exemplo:
http://www.psy.herts.ac.uk/wiseman/papers/MediumBJP.pdf e a parte da conclusão descrita abaixo:
These findings can be interpreted in various ways. It is possible that genuine
mediumistic ability does not exist, and that the apparent accuracy of mediums’ readings
are entirely due to the type of psychological stratagems outlined in the first section of
this paper. This interpretation is consistent with much of the sceptical literature on
alleged mediumship (see e.g. Gardner, 1992; Hyman, 1977), previous work that has also
failed to find evidence of such abilities under controlled conditions (see Schouten, 1994,
for a review of this work) and those arguing that the studies that have obtained positive
results are methodologically flawed (e.g. Hyman, 2002, 2003). This interpretation is also
consistent with the fact that the presence of some of these strategies (e.g. length and
diversity of reading, generality of statements) appeared to be associated with the ratings
assigned by sitters to the readings obtained in this study. If this interpretation is correct,
then the most productive direction for future work in this area is to examine these
stratagems more closely, examining, for example, the types of people that tend
to endorse mediumistic readings and the forms of rhetoric that alleged mediums use to
convince sitters that they are receiving messages from their deceased friends and
relatives (see e.g. Wooffit, 1992, 2001). Alternatively, it is possible that genuine
mediumistic abilities do exist, but that this study failed to find evidence of them because,
for example, the mediums involved in the experiment do not possess such abilities or
the setting in which the study was conducted did not elicit such abilities. These
hypotheses can only be evaluated by systematically var ying these factors in future work,
providing that such work also eliminates the various methodological problems.
Outra coisa. Convém separar a manifestão dos supostos fenômenos "paranormais" mediúnicos da suposta manisfestação de espíritos. Uma coisa não tem nada a ver com a outra até que se prove que existam fenômenos mediúnicos autênticos, a existência de espíritos e que esses usam médiuns para se interagir com a nossa realidade. Até agora, não temos evidência alguma disso. Essa confusão é uma das inúmeras bobagens divulgadas por Kardec.
