" It’s not in keeping with the scientific model to investigate a purportedly haunted location with the intent to prove that ghosts exist. The paranormal researcher should remain neutral and unbiased throughout the investigation and let the data prove a definitive conclusion, whether that’s the one they wanted or not. They should walk into an investigation thinking, “I will document what happens and then examine the data for conclusions. "
