The Roots of Coincidence

Blurb

The Roots of Coincidence is a 1972 book by Arthur Koestler, an introduction to theories of parapsychology, including extrasensory perception and psychokinesis. Koestler postulates links between modern physics, their interaction with time and paranormal phenomena. It is influenced by Carl Jung's concept of synchronicity and the seriality of Paul Kammerer.
The psychologist David Marks criticized the book for endorsing pseudoscience. Marks noted that Koestler uncritically accepted ESP experiments and ignored evidence that did not fit his hypothesis. Marks coined the term "Koestler's Fallacy" as the assumption that odd matches of random events cannot arise by chance. Marks illustrates the fact that such odd matches do regularly occur with examples from his own experience. John Beloff gave the book a mixed-review, describing it as "a typical Koestlerian performance" but noted that some of his claims about psychical research were inaccurate.
