origin: [1930's] American; "Fort" + -ean from Mr. Charles Fort, the original & real life Agent Mulder.
adjective (noun = Forteans)
Pertaining to supernatural activity, or strange phenomenas that science may not have been able to properly classify or explain: aliens, The Lock Ness monster, spontaneous human combustion, etc.
Mr. Charles Fort wrote The Book of the Damned; the title of the book referred to what he termed the "damned" data - data which had been damned, or excluded, by modern science because of its not conforming to accepted guidelines. The way Fort saw it, mainstream scientists are trend followers who believe in what is accepted and popular, and never really look for a truth that may be contrary to what they believe. He also compared the close-mindedness of many scientists to that of religious fundamentalists, implying that the supposed "battle" between science and religion is just a smokescreen for the fact that, in his view, science is, in essence, simply a de facto religion. - Wikipeadia
