I'm sure there must have been a time or two when we've all wished for a second to be re-plugged in become blissfully ignorant once more - no-zombie
It seems an ignorance position is somewhat desirable as it is usually easier. A JW only needs to do as they are told with no further thinking or decision making needed. They are not responsible for their actions but are only following directions given.
While many JWs are conditioned to think in an institutional manner, I believe some may be prone to think as a gambler does.
JWs are conditioned to believe they won't die and their loved relatives who have died, will be resurrected. Even if a JW recognizes the religion's problems and errors, the thought of abandoning it means they must accept they will die and loose hope to see their departed relatives again. No one wants to die or experience loosing someone they love so it's usually harder to accept, the JWs/WT may also be wrong about resurrection and death.
To a gambler that has bet much money but hasn't won, typically holds the belief that the next hand, coin or roll of the dice will be the one that pays off. Similarly, if the JW doesn't give up hope but remains a JW for just a short time longer, then it will finally pay-off.
