I think developing judgement and insight are part of the process of recovery. Learning to see beyond the presentation changes how you see meetings.
Personally, I think that it is the culture of only sharing experience, strength and hope that brings about the issue you are discussing. In my experience, when people try to share their trouble or be honest about the negative things in the life, the greeter and others tell them that they are living in the problem rather than the solution.
How to foster honesty? Praise it when you hear it. You know some folk are working against it, so it is up to individuals to support any honesty we hear. Our first instinct is to fight dishonesty. I think that is a losing game. Encouraging honest is slow but effective.
