Who said that? #2

  "The security provided by a long-held belief system, even when poorly
  founded, is a strong impediment to progress.  General acceptance of a
  practice becomes the proof of its validity, though it lacks all other
  merit."   - Dr. B. Lown, invented defibrillator
Or more simply put:
"There are some people that if they don't know, you can't tell 'em."
         - Louis Armstrong
"The mind likes a strange idea as little as the body likes a strange
  protein and resists it with similar energy.  It would not perhaps be
  too fanciful to say that a new idea is the most quickly acting antigen
  known to science."   - Wilfred Trotter, 1941
This describes a kind of "ideological immunity'
 How do you explain this kind of willful ignorance?
On the other hand how do you explain exceptions, how do you explain the ready acceptance of new ideas?
