Paradigms as physiological filters

“Our paradigms act as physiological filters - we see the world through our paradigms. This means that any data that exist in the real world that do not fit our paradigm will have a difficult time getting through our filters. The data that do fit our paradigm not only make it through the filter, but are concentrated by the filtering process. Therefore, what we actually perceive is dramatically determined by our paradigms. What may be perfectly visible, perfectly obvious, to persons with one paradigm, may be quite literally invisible to persons with a different paradigm.”
