Progress can cause people to go two ways, they go with it, or they go against it. Which is of course obvious except that those who fight against it usually snap back very hard. They don't just stay where they are, they end up gravitating to the very hard rules of what they perceive as the way things were. This lets them feel much more comfortable as the world around them changes. The more it changes, more people hit some limit and start snapping back. Science isn't the only thing that progresses one funeral at a time.
