Reality tunnel is a theory that, with a subconscious set of mental filters formed from beliefs and experiences, every individual interprets the same world differently, hence "Truth is in the eye of the beholder". It is similar to the idea of representative realism, and was coined by Timothy Leary (1920–1996). It was further expanded on by Robert Anton Wilson (1932-2007), who wrote about the idea extensively in his 1983 book Prometheus Rising. Wilson and Leary co-wrote a chapter in Leary's 1988 book Neuropolitique (a revised edition of the 1977 book Neuropolitics), in which they explained further: The gene-pool politics which monitor power struggles among terrestrial humanity are transcended in this info-world, i.e. seen as static, artificial charades. One is neither coercively manipulated into another's territorial reality nor forced to struggle against it with reciprocal game-playing (the usual soap opera dramatics). One simply elects, consciously, whether or not to share the other's reality tunnel. Considerations Every kind of ignorance in the world all results from not realizing that our perceptions are gambles. We believe what we see and then we believe our interpretation of it, we don't even know we are making an interpretation most of the time. We think this is reality. – Robert Anton Wilson The idea does not necessarily imply that there is no objective truth; rather that our access to it is mediated through our senses, experience, conditioning, prior beliefs, and other non-objective factors. The implied individual world each person occupies is said to be their reality tunnel. The term can also apply to groups of people united by beliefs: we can speak of the fundamentalist Christian reality tunnel or the ontological naturalist reality tunnel. A parallel can be seen in the psychological concept of confirmation bias—the human tendency to notice and assign significance to observations that confirm existing beliefs, while filtering out or rationalizing away observations that do not fit with prior beliefs and expectations. This helps to explain why reality tunnels are usually transparent to their inhabitants. While it seems most people take their beliefs to correspond to the "one true objective reality", Robert Anton Wilson emphasizes that each person's reality tunnel is their own artistic creation, whether they realize it or not. Wilson — like John C. Lilly in his 1968 book Programming and Metaprogramming in the Human Biocomputer — relates that through various techniques one can break down old reality tunnels and impose
