Of course, every JW contends with doubts and cognitive dissonance. I suspect every JW’s has doubts that wax and wane, but never fully goes away. But the barrier of undue influence is steep and keeps them from making a real examination of things like 607, 1914, whether world conditions have been getting worse since 1914, the organization’s many failed predictions…
Until there is such a real examination or reality testing, doubt can easily go both ways. If a JW comes to the conclusion that the end is not around the corner, they might have fearful doubts about that conclusion. “What if it is?”
To some extent, I believe many JWs, while to some extent do believe it, have an authentic corner of their identity that does not fully buy in to the full implications to the teaching that the Armageddon is very close and that most of their non-JW acquaintances, family, coworkers, neighbors, and seven billion others are about to be murdered for all eternity. Of course, this might include inactive and irregular JW, and to some extent, those who were active and could’ve arranged their circumstances to preach more. Otherwise, they would do as the Org prescribed and pioneer, or sell their homes and move to where the “need was greater”, or try to get into Bethel.
Many do live practical lives with day jobs, having a place to live and making plans for the near future to some extent. Of course, Armageddon does still loom in their minds and effects their decisions. They seem caught between fear and the practical. That tension is not easy.
