Very few “ normal intelligent “ people join the religion. Those that did were pretty reasonable people and they didn’t believe everything Mother taught them.
In our area a very successful Medical Doctor joined the religion. Several year prior he left his wife & children to marry a DFd JW employee. Now that slutty DFd JW woman was married and not "sleeping around" she was reinstated; got him to "study"; and he was reeled in.
I have yet to come to understand how someone intelligent enough to have a medical degree, can believe all the Genesis bullshit that JW's believe is all literal! Does such a person just close their eyes to the BS and do what it takes to make the young wife happy?
