I believe that many older people find critical thinking to be taboo, and prefer to take things at face value because they confuse passivity with wisdom. Why question something when someone will come along any minute to make you feel comfortable anyway?
They tend to be wrong when they think independently because they were never any good at critical thinking to begin with, so they just parrot what they were told makes sense. What's going to keep their lives "the same."
This article does a better job than I ever could explaining my reasoning... https://journals.sagepub.com/doi/abs/10.1177/014616721243921...
