honoring the heroes of

skeptical inquiry

Eyewitness Testimony: Many subscribe to the old adage, "Seeing is believing," but eyewitness testimony is among some of the more unreliable findings admitted into any investigation. Paranormal investigations are no exception. Although clients provide personal accounts of activity as part of the Prelim process, investigators cannot use these as findings. Rather, they must depend on a combination of their own personal accounts and the documented findings they capture on the investigation. Even the eyewitness testimony of investigators remains the most subjective and least reliable form of findings in the report. It is significant only if there are correlations between subjective experience and documented findings, or patterns among independent reports of experiences.
