Some of them probably know deep down inside that the answer to that question is a lot of things and they aren’t ready for that. Finding out the answer to that question also means having to research and do your own thing different from what most do. Some people probably aren’t ready for that to.

9/11 is a classic example. It’s a pretty horrifying realization for some people, many who have been raised to have a general trust in authority, to come to grips with the fact that not only does their government not have their best interests at heart, but will gladly kill them and millions of civilians to support a narrative in the name of profit and massively expanded powers to conduct surveillance.
Because it would require change. Not many are willing to change. Ignorance is bliss
