I think it boils down to the fact that people don’t want to THINK. It is a big, scary world out there, full of uncertainty, danger, and ultimately death. As long as they are comfortable enough, they will swallow any lie they are given. If they start to question the narrative, they will quickly see that everything collapses. This is a scary thing to accept, and would shatter what most people perceive as reality. They would rather be comfortable in the matrix, than know the truth and be in a war.
