Ghosts

My Positions

  1. There is no good reason to believe that ghosts are real.
  2. I do not hold that ghosts exist, and I act in the world as though they do not.

Notes

  1. Ghost claims rest entirely on anecdote, and anecdote is the weakest form of evidence (Experiential Argument). No ghost has ever been detected under controlled conditions, despite over a century of organised attempts, beginning with the Society for Psychical Research in 1882.
  2. The reported phenomena (cold spots, noises, apparitions, the sense of a presence) have well-documented natural explanations: infrasound, carbon monoxide poisoning, sleep paralysis and hypnagogic hallucination, pareidolia, suggestion, and the ordinary unreliability of memory.
  3. The concept is incoherent on its own terms. A ghost is supposed to be immaterial yet visible, able to pass through walls yet stand on floors, and to wear clothes, which raises the question of why cotton has an afterlife.
  4. If consciousness is a product of the brain (Consciousness, Mind-body dualism), then there is nothing that could persist after the brain stops to do the haunting. The ghost claim is a special case of the afterlife claim and fails for the same reasons.
  5. Belief in ghosts remains common (roughly a third to a half of adults in UK and US surveys) because the brain is a pattern-detecting, agency-attributing machine, and the cost of a false positive ("something is there") was historically lower than the cost of a false negative. See Confirmation Bias and Appeal to Ignorance ("you can't prove it wasn't a ghost").
