My mother was receptive to the JW in 1955 because:
1. Her father died when she was just entering her teens, and she was "Daddy's girl;" she missed him very much. So the promise of a resurrection "any minute now" had tremendous appeal for her.
2. She was in an unhappy marriage and wanted to have God make things better for her "any minute now."
3. Like EVERYONE at that time, she was concerned about the threat of nuclear annihilation; God would make things better for everyone "any minute now."
4. She was uneducated; when her Father died, her Mother took her out of school and put her to work on her white-trash hillbilly farm. (My grandmother was probably at least half crazy AND ignorant AND cruel.) My mother never developed a mature perspective on the world that could have neutralized the Watchtower's yammering. She didn;t have any idea about how "the world" worked.
She's 90 now and a desperate "Klingon."
"Klingon to The Kingdumb like you didn't know better."
