Reality Tunnel

''a (myopic) system of thoughts (mostly consistent) that a human chooses or is foisted upon them by parents, culture, society, institutions, etc. to guide the human biosystem through his/her environment. Most people seem to go through the tunnel without ever questioning what is outside it and who built it, and what other choices there are as far as models.'' (cut'npasted from fUSION Anomaly)
