I would hesitate to get ahead of myself in this line of reasoning. Generalizations can certainly be made. There may even be hard data that illustrates poor education levels among professed JWs. After all aspirations usually top out at regular pioneer or Bethel service. Good grades in school are not necessary. College is not encouraged.
Yet, there is an undeniably percentage of active JWs that are highly educated and financially secure because of it. Certain congregations are noted for the level of prosperity simply by the cars parked in the lot.
Education and thinking abilities are not all it takes to “wake up” or escape from the cult.
In my experience some of the simplest minds were able to break free first.
Before we pat ourselves on the back, I think we have to acknowledge that even extremely intelligent people can be controlled by undue influence.
If we assume this shit eating grin stance, it might be more than the effort we want to waste in rescuing “ignorant” ones from the cult.
There are watchtower apologists that could eat most everyone for breakfast in this forum or others. Ask yourself, are you up to the task to take them on? Sure they are few and far between, but don’t get lazy assuming everyone still stuck in the cult is stupid.
