I recently saw a clip of someone speaking about "coming out of the closet," and her definition of a "closet" was any situation in which one perpetually pretends. She mentioned that the body will inevitably produce cortisol when it's under that kind of stress, and for the first time I realised that indefinite pretending could really damage a person. It was a scary thought, as it's hard to visualise an end point in slow-moving and potentially never-changing situations. At least, within the parameters of current perception, that is.
One can always find reasons to stay when cognitive dissonance is in effect. Talesin, you gave a hell of an example. It made me think about the rationalisations of the abused being equally applicable in relationships and at the hands of fundamentalist groups.
I also just remembered Stockholm Syndrome - the sense of being addicted to one's captor. I suspect it may have some overlap with the experience of cognitive dissonance. Can anyone relate to this, whether within the org or within a relationship?
