Jacques Vallee
<p>Jacques Vallee has actually entertained the theory. In his book <cite>Messengers of Deception</cite>, Vallee writes:</p>
<blockquote>
<p>UFOs are real. They are an application of psychotronic technology; that is, they are physical devices used to affect human consciousness. They may not be from outer space; they may, in fact, be terrestrial-based manipulating devices. Their purpose may be to achieve social changes on this planet. Their methods are those of deception: systematic manipulation of witnesses and contactees; covert use of various sects and cults; control of the channels through which the alleged “space messages” can make an impact on the public.(21)</p>
