My point is that perceptual bias can affect nut jobs and scientists alike. If we hold too rigidly to what we think we know we ignore or avoid evidence of anything that might change our mind.
Science is simply common sense at its best that is rigidly accurate in observation and merciless to fallacy in logic.
Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.
