honoring the heroes of

skeptical inquiry

Apophenia: A natural psychological tendency in which patterns are discenred in random information, apophenia is the basis for other perceptual phenomena, such as pareidolia, auditory matrixing, confirmation bias, and divination. Critics of EVP frequently rely on apophenia as a catch-all explanation for why listeners identify anomalous voices in the audio medium and see ghosts in the photographic findings. Conscientious paranormal investigators, however, are vigilant self-observers and use skeptical thinking and the peer review process to avoid incidents of apophenia in their findings.

The Bitter Pill

One of the common problems that any paranormal investigation group eventually encounters is the delicate issue of prescription medications clients take, but which they are often reluctant to discuss with anyone but family.

PPI Presents...

Join real-life paranormal investigators from TAPS Family group, Pacific Paranormal Investigations, for a spooky Halloween multi-media presentation with a skeptical view of the science and the pseudoscience of modern paranormal investigating. Enjoy media clips from PPI’s private cases that will leave you laughing, dumbfounded, creeped out, or all of the above. Find out about modern “ghost” hunting technology, the methodology of skeptical inquiry, and the critical thinking tools needed to evaluate ghost “evidence” while at the same time avoiding the pitfalls of pseudo-science and cognitive bias. Learn how to get started as a paranormal investigator with recommended reading and an invitation to join local ghost and paranormal meetup group, SDGAP. It’s fun, always free, and open to the public.
