nonjwspouse: Are JWs "mind trained" to be habitual liars?
Yes.
A basic requirement of honesty is that an individual knows what the truth is to begin with. A cult does not foster individual introspection or the development of an authentic personality. The only personality/identity allowed is the cult identity.
So, therefore, what you basically have with a JW, or someone raised in a cult environment, is a shell. An empty shell. A cult person on the outside with nothing on the inside. Anything on the inside that doesn't fit that outside personality is suppressed and denied. To be a cult member, you have to lie - you have to lie about who you authentically are.
When a person has no truth inside to tell, they will lie. They have to. They wouldn't exist otherwise...their lie is the only thing they have.
To become authentic is painful. It hurts. So it is easier to take that personal pain and give it to other people. By lying. The lie eases the pain of either not having an authentic personality, or having to suppress the authentic person that you really are.
