The term ‘haunting’ is generally applied to cases involving recurrent phenomena, of a supposedly paranormal nature, that are associated with particular places. Approaches to understanding hauntings can be divided into two categories: those that attempt to explain the manifestations ‘naturalistically’ (e.g. in terms of the misinterpretation of normal sounds or the effects underground water), and...

Dear Editor: The article “Finding and Correcting Flawed Research Literatures” by Delgado-Romero and Howard (2005) provides an ironic example of flawed research. I will restrict my comments just to their treatment of the ganzfeld telepathy test. Delgado-Romero and Howard (2005) were motivated to reexamine the ganzfeld effect because they suspected that the previous meta-analytic estimates of the...

This paper will explore the relevance of the subject of psi phe­ nomena to important topics in psychoanalysis and psychotherapy, such as intersubjectivity, projective identification, and the inte­ gration of primary and secondary process experience. “Psi” is a general term referring to kinds of information transfer or com­ munication that exceed common understanding of how such communication ta...

Imagine that Alice and Bob, unable to communicate, are both given a 16bit string such that the strings are either equal, or they differ in exactly 8 positions. Both parties are then supposed to output a 4-bit string in such a way that these short strings are equal if and only if the original longer strings given to them were equal as well. It is known that this task can be fulfilled without fai...

We describe a method of quantifying the effect of Questionable Research Practices (QRPs) on the results of meta-analyses. As an example we simulated a meta-analysis of a controversial telepathy protocol to assess the extent to which these experimental results could be explained by QRPs. Our simulations used the same numbers of studies and trials as the original meta-analysis and the frequencies...
