John Perry Barlow defined pronoia as the suspicion the Universe is a conspiracy on your behalf. The academic journal "Social Problems" published an article entitled "Pronoia" by Fred H. Goldner in 1982 (vol 30, pp.82-91). It received a good deal of publicity at the time including references to it in Psychology Today, The New York Daily News, The Wall Street Journal etc. It described a phenomenon that was the opposite from paranoia and provided numerous examples of specific persons who displayed such characteristics.
It was subsequently picked up in England and written about as described below. Wired Magazine published an Article in Version 2.05 (May 1994) titled Zippie!. The cover of the magazine featured a psychedelic image of a smiling young man with wild hair, a funny hat, and crazy eyeglasses. Written by Jules Marshall, the article announced an organized cultural response to Thatcherism in the United Kingdom of Great Britain and Northern Ireland. The opening paragraphs of the article describe "a new and contagious cultural virus" and refer to the term pronoia as "the sneaking feeling one has that others are conspiring behind your back to help you".
The article announces a cultural, musical, invasion of the United States to rival the British Invasion of 1964-1966, culminating with a "Woodstock Revival" to be staged at the Grand Canyon in August of 1994. The spokesperson for the Zippies, Fraser Clark, dubs this movement the "Zippy Pronoia Tour".
The principal proponent of pronoia in the 21st century has been the astrologer, writer, poet, singer, and songwriter Rob Brezsny. Brezsny's book Pronoia Is the Antidote for Paranoia: How the Whole World Is Conspirin'g to Shower You with Blessings', published in 2005, explores the philosophy of pronoia.
"Pronoia is the positive counterpart of paranoia. It is the delusion that others think well of one. Actions and the products of one's efforts are thought to be well received and praised by others. Mere acquaintances are thought to be close friends; politeness and the exchange of pleasantries are taken as expressions of deep attachment and the promise of future support. Pronoia appears rooted in the social complexity and cultural ambiguity of our lives: we have become increasingly dependent on the opinions of others based on uncertain criteria."This quote is taken from Goldner's article listed above.
