Koestler Parapsychology Unit

Arthur Koestler, the Hungarian born writer best known for the novel Darkness at Noon, had a lifelong interest in psychical research and left a substantial bequest in his will to fund a university chair in parapsychology in Britain, stipulating that it be held at a university of good standing. After Koestler's death by suicide in 1983, alongside his wife Cynthia, his estate approached several British universities, and the University of Edinburgh agreed to establish and house the chair, becoming home to the only endowed professorship of parapsychology in the United Kingdom.

The university appointed Robert L. Morris, an American psychologist who had trained at J. B. Rhine's Institute for Parapsychology in North Carolina and built a reputation for methodologically careful, skeptically minded experimental work, as the first Koestler Professor of Parapsychology from December 1985. Morris used the position to recruit additional staff and postgraduate students, forming the Koestler Parapsychology Unit as a working research group within the university's psychology department rather than leaving the chair an isolated position, and the Unit quickly became a training ground for a new generation of researchers including Deborah Delanoy, Caroline Watt and Julie Milton, several of whom went on to lead parapsychological research programs of their own elsewhere.

Much of the Koestler Unit's research program centered on the ganzfeld procedure, an experimental design using mild sensory deprivation intended to test telepathy under conditions that reduce ordinary sensory cues, which had become the most actively debated method in the field after psychologist Charles Honorton and skeptic Ray Hyman published a joint statistical analysis of earlier ganzfeld studies in 1986.

Unit researchers Julie Milton and Richard Wiseman published a widely cited 1999 meta-analysis of ganzfeld studies conducted after that joint statement, finding that the apparent psi effect had not been replicated across the newer body of experiments, a result that became a central piece of evidence for skeptics even though it was produced by researchers working inside a parapsychology unit rather than by outside critics.

The finding illustrates the Unit's general approach under Morris, which emphasized methodological self scrutiny and was often more critical of weak evidence than outside observers expected from a dedicated parapsychology laboratory. Morris served as Koestler Professor until his death in August 2004, after which the university continued to support parapsychological teaching and research, including the Koestler Parapsychology Library, within its School of Philosophy, Psychology and Language Sciences, maintaining Edinburgh's position as the principal United Kingdom academic center for the field even as the endowed chair itself was not immediately refilled.
