Christina Baldwin said this quote

When story and behavior are consistent, we relax; when story and behavior are inconsistent, we get tense. We have a deep psychological need for our stories and behaviors to be consistent. We need to be able to trust the story, because it's the lens through which we see reality. We will go to great lengths in the attempt to make a story that explains an action and supports or restores consistency. If we cannot make story and action fit, we either have to make a new story or change the action. ... [But] The drive for consistency and the ability to redefine abhorrent action so it fits the story are very complex issues. We have a huge ability to continue believing stories we are told are true in order to stay comfortable with actions we don't want to change, or don't feel capable of changing.
