Hi Franzio  I dont make light of the overlaps or risk factors but a phone poll by a marketing company asking about common paranormal beliefs does not provide much valid evidence in this regard As the rest of the article cites academic and peerreviewed work I dont see the need to make an exception for such a weak piece of research particularly when more rigorous work is already cited  The issue isnt specific to schizophrenia and applies to the spectrum of psychosis and psychosislike experience Should we put the same discussion in every article about a psychosisrelated condition Its is much better included in the article on delusions In fact there could really do with an article being created on the continuum model of psychosis that deals with the spectrum of both these sort of beliefs and anomalous perceptual phenomena  Particularly with an article of this length reducing clutter is a priority and in light of the existing citations to quality research a poll by a marketing company certainly strikes me as clutter
