Robert Kegan’s wikipedia entry has a pretty good summary of the idea.
This 15 min. youtube video is also a nice introduction.
In short, the real reason people don’t do the things they consciously want to do might be related to a sort of immune system that tries to keep things as they are because there are competing commitments that steam from unconscious assumptions. e.g. a person might not take their heart medication because taking medication is associated with end of life and they have a competing commitment to not perceive themselves as being at the end of their life.
The truth I was referring in the previous comment is Scientific understanding.
Also, when I said story I did not meant a work of fiction but more like an work of vision.
Something like a reimagining of what life could be for the human race and the commitment to implement that vision as expressed by the people telling the story and living the story.
