Obviously, the faster we process information, the more rich and complex our models or glosses - our reality-tunnels - will become.
Resistance to new information, however, has a strong neurological foundation in all animals, as indicated by studies of imprinting and conditioning. Most animals, including most domesticated primates (humans) show a truly staggering ability to "ignore" certain kinds of information - that which does not "fit" their imprinted/conditioned reality-tunnel. We generally call this "conservatism" or "stupidity", but it appears in all parts of the political spectrum, and in learned societies as well as in the Ku Klux Klan.
