All 'anti-vaccine' and 'damorish' types I met were undereducated in one way or another. Not necessarily in terms of university education, often it was some gap in basic self-education resulting in the lack of quality reasoning or soft skills or breadth of knowledge. On the side of an average person, there are many other enemies of science like absence of intellectual honesty, sincere pursuit of truth and ability to work towards it (often combined).
