I think it explains what I sometimes find unfathomable as a born-in who left - why on earth does anyone ever join the WTS when there is lots of information about them. It's not that they are suckered or conned as many imagine, it's that they are actively looking for something that matches the WTS brand of religion.
Yes I struggle to understand anyone joining as an adult, especially now in our information rich society. When we left we got involved with a research group of sociologists and anthropologists at the London School of Economics called INFORM, Information focus on new religious movements. My husband was asked to give a talk at one of their seminars.
They believed that the problem is with raising kids with a basic religious belief like Anglicanism for example is that they are taught an unrealistic and idealistic view of human behaviour. Nobody tells them that actually people aren't kind all the time, they don't always love their neighbour and far from turn the other cheek it's human nature to hold grudges and be unforgiving.
So these kids are then rich pickings for cults that stand outside colleges and universities and tell them that there are true Christians who really care about their fellow man and the planet and they are welcome to come meet them. We know the rest, these possibly lonely, away from home, teenagers who have been raised with unrealistically high expectations af humanity are then love bombed by wonderful new 'friends'. They think here at last are the people I was taught to believe existed when I was small and went to Sunday school.
It made sense to me. I could see how people get sucked into cults even when they are not particularly religious or looking for anything because a) they've been given unrealistic expectations of people from childhood and b) cultists pretend to be those perfect people until they are too emotionally involved to get out.
