OTWO,
I have found, repeatedly so, that the "need to be right" spills over into every aspect of a JWs life. If they are doing something incorrectly in their work, they will not accept correction no matter how delicately it is presented. You can show documented and proven why the correct procedure should be used. They will still do things their own way.
I can't help but wonder...is it because the WT breeds a certain kind of stiff necked arrogance among them that they cannot be wrong about anything? Or is it a personality flaw that JWs are born with naturally?
It is an enigma to me, but I see the pattern repeated in the few JWs that I know.
