I agree with the thoughts expressed, different strokes for different folks.
I do take your question that you are asking as getting out of her mentally and not because they were horny of some such but still believed.
Some witnesses don't really know why they think it is "the truth" they just do.
Some like me have a slightly rough idea of the storyline "607-1914-chronology-1918-chosen-etc" and just accept what we have been told without checking because THEY wouldn't lie to us.
Some don't really care too much they have family/friends and they don't do much, don't study, only come so often, and only go "OUT" once a month to keep regular.
For me, it wasn't until I said to myself that I need to KNOW what I say I believe and started researching things.
Whatever it is, it has to get them to that "Well DAMN!" point.
