I respect Mary Roach as a scientist, for going out and researching really specific and odd things. Her other book that I've read, Stiff, is just as fascinating, although much grosser. She honestly inspires me to go into journalism.
Some things that I learned from this book include:
- The debunking of spirit encounters via infrasound
- The history of EVPS
- The beginning of spiritualism in America
I'm going to focus on the first two things because those excited me the most. Infrasound, according to Roach, are "inaudible, low-frequency sound waves...[and] runs from zero to twenty hertz." The effects of infrasound on the human body include "strange feelings in the stomach", the raising of hair on the back of the neck, vibrating eyeballs (what the hell), cold chills, and increased heart rate. Infrasound has already been used to explain some of the phenomena occurring at Warwick Castle in England (pg. 227).
I'm looking forward to seeing how infrasound, in addition to EMFs, can be used as a debunking tool in paranormal investigations. You can order infrasound detectors online or use an app on your smart phone.
EVPs are endlessly fascinating to me, which is why I was excited that Roach included a chapter about the history of them. I knew nothing about the history of EVPs before this delightful book. EVPs (*Zak Bagans voice* or electronic voice phenomena) grew popular around the same time that radio, television, and microwaves did. People found the new technology just as mystical and otherworldly as the possibility of communicating with the dead. The idea that you could get spirit voices via electronics seemed pretty reasonable. Also humans have a knack of finding voices in white noise. We're programmed to pick out faces and voices, even when there aren't any. This explains why we have so many photos of alleged "faces in windows" and whatnot.
Not to say that all ghost photographs and EVPs are fakes, it's just important to recognize the phenomena of matrixing.
