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".
– Robert Anton Wilson[2][3] 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.
This is attempted through various processes of deprogramming using neuro-linguistic programming, cybernetics, hypnosis, biofeedback devices, meditation, controlled use of hallucinogens, and forcibly acting out other reality tunnels.
In line with Kantian thought,[5] as well as the work of Norwood Russell Hanson, studies have indeed shown[6][7][8][citation needed] that our brains "filter" the data coming from our senses.
This "filtering" is largely unconscious and may be influenced—more-or-less in many ways, in societies and in individuals—by biology,[9][10][11] cultural constructs[12] including education and language[13] (such as memes), life experiences,[14] preferences[15] and mental state,[16][17] belief systems (e.g. world view, the stock market), momentary needs, pathology, etc.
Similarly, the philosophy of life Pyrrhonism seeks to overcome these conditioned realities by inducing epoche (suspension of judgment) through skeptical arguments.
