David Clarke summarizes in his book the psycho-social hypothesis in the following fundamental concepts .
- There is no such as the UFO phenomenon, but there are lots of phenomena that cause UFO
- There is no such thing as “True UFO”.
- Extraordinary claims require extraordinary evidence.
- Accounts of UFO experiences form the core of the syndrome but stories do not constitute “evidence”, they are folklore.
- Culture not experience creates the UFO interpretation but some experiences are independent of culture.
- The UFO syndrome fulfils the role of the supernatural “other”.
- The extraterrestrial hypothesis and other exotic theories cannot explain UFOs.
- The idea of a superconspiracy to hide the truth about UFOs is unfalsifiable.
- The common denominator in UFO stories is the human beings and see in believe in them. People want to belief in UFOs.
