The Psychology Branch of the Air Force's Aeromedical Laboratory took a pass at the psychological angles. They said, "there are sufficient psychological explanations for the reports of unidentified objects to provide plausible explanations for reports not otherwise explainable." They pointed out that some people have "spots in front of their eyes" due to minute solid particles that float about in the fluids of the eye and cast shadows on the retina. Then they pointed out that some people are just plain nuts. Many people who read the Grudge Report took these two points to mean that all UFO observers either had spots in front of their eyes or were nuts. They broke the reports down statistically. The people who wrote the report found that over 70 per cent of the people making sightings reported a light- colored object. (This I doubt, but that's what the report said.) They said a big point of these reports of light-colored objects was that any high-flying object will appear to be dark against the sky. For this reason the UFO's couldn't be real. I suggest that the next time you are outdoors and see a bomber go over at high altitude you look at it closely. Unless it's painted a dark color it won't look dark. The U.S. Weather Bureau wrote an extremely comprehensive and interesting report on all types of lightning. It was included in the Grudge Report but contained a note: "None of the recorded incidents appear to have been lightning." There was one last appendix. It was entitled "Summary of the Evaluation of Remaining Reports." What the title meant was, We have 23 per cent of the reports that we can't explain but we have to explain them because we don't believe in flying saucers. This appendix contributed greatly to the usage of the analogy to the Dark Ages, the age of "intellectual stagnation." This appendix was important--it was the meat of the whole report. Every UFO sighting had been carefully checked, and those with answers had been sifted out. Then the ones listed in "Summary of the Evaluation of Remaining Reports" should be the best UFO reports--the ones with no answers. This was the appendix that the newsmen grabbed at when the Grudge Report was released. It contained the big story. But if you'll check back through old newspaper files you will hardly find a mention of the Grudge Report.
