A leader who believes in others and the value of their opinions and conveys self-confidence without authoritarianism shows good faith. That leader turns questions over to the group whenever possible, rather than casting himself or herself in the role of expert or authority. This technique is most appropriate for open-ended questions that can draw upon the wisdom of the group for answers. I'm not sure about that. The leader demonstrates faith that people can find their own answers.
Good leaders have a positive attitude toward group members.
They try to emphasize what participants are doing right, not what they are doing wrong. Leaders believe the participants have the ability for further growth. For example, it is important for you to convey the attitude that each dad wishes he could be a better dad, that all have things they do well and all have things they regret doing as a dad. Thus, all dads, including the leader, are in the same boat, on the way to being better dads. Nobody, not even the leader or people who write books on fathering, has all the answers.
