Good discussion here on hypnotic language patterns.

You also need to understand there are other ways to influence peoples behavior without 'controling their mind'. If thru the meeting and literature they can plant ideas and suggestion that slowly regulate the way people think Mission accomplished.
One thing I note about Dubs is when they ask the dub Questions there is no more proof of the conditioning that has affected them.
Example:
(you see a dub you haven't seen in a while) Oh what hall are you at? When you guys assembly? (if you are a man who has 'served) oh we need to have you over to give a talk!
These are not normal patterns of speech and connecting with people they are forms of Dub conditioning. JW's have a conditioned pattern of speech and questions to find out the status of the Dub they are talking to and to convey their status.
Example:
(Again dub you see) Oh Iam aux pioneering this month! We just had our assembly! My child just...(gave his/her 1st talk got baptized etc.)
What I like to do is ask them why they ask such questions and try and get them to fall into a loop snarl of conflicting programing. Or better yet point out the control as its taking over their minds and next question.
Example:
(dub ask why I dont go to the hall) Why do you want to know is it so that you can categorize me and judge my worthiness or do you want to know the actual reasoning behind me decision?
That last example came from Blondie, I hope I did it justice. But if you can reconize the conditioning that goes on, especially as dicussed in the link above, you can better understand the mind-set and control that has affected the Dub reasoning.
