Personally I think most people prefer to be ignorant because its easier that way.
I don’t know if it is most people but it surely is true for many people.
Responsibility frightens some people and ignorance relieves them of the responsibility that comes with becoming informed. They cling to ignorance as an excuse to avoid reality. Indeed, they can avoid reality but they can’t avoid the consequences of avoiding reality.
Many of those same people also display a fear of freedom because of the responsibility that comes with freedom.
