As a serious researcher on the psychology of belief systems, I was very disappointed at the deceptiveness of the authors' approach. While they seemingly did a great deal of research, it was selected mainly for its usefulness in their plan to engender fear in order to promote conversions. They even repeatedly stated that the material should make the reader fearful. Please, gentlemen, if you yourselves are so fearful, spare us your hysteria.Material which could well deserve careful and sensitive analysis was instead treated with the utmost credulity, a criticism that has also been leveled at Missler's treatment of the Apocalypse and even the Y2K computer problem (the so-called Millenium bug).
