vallée also proposes that a secondary aspect of the ufo phenomenon involves human manipulation by humans. witnesses of ufo phenomena undergo a manipulative and staged spectacle, meant to alter their belief system, and eventually, influence human society by suggesting alien intervention from outer space. the ultimate motivation for this deception is probably a projected major change of human society, the breaking down of old belief systems and the implementation of new ones. vallée states that the evidence, if carefully analyzed, suggests an underlying plan for the deception of mankind by means of unknown, highly advanced methods. vallée states that it is highly unlikely that governments actually conceal alien evidence, as the popular myth suggests. rather, it is much more likely that that is exactly what the manipulators want us to believe. vallée feels the entire subject of ufos is mystified by charlatans and science fiction. he advocates a stronger and more serious involvement of science in the ufo research and debate. only this can reveal the true nature of the ufo phenomenon.
