I am reading The Presentation of the Self in Everyday Life by Erving Goffman at the moment. It sheds much light on the experience of 'performing' the role of being a Jehovah's Witnesses: how a Witness will strictly adhere to Watchtower standards when we are 'frontstage' with an audience either of peers or outsiders, and how they may relax those standards when they are 'backstage', not in a setting where their fidelity to the identity of 'Jehovah's Witness' is being scrutinized.
An interesting point it makes is that we can present our roles either with 'sincerity' if we believe in the performance as much as we would have the audience, or with 'cynicism' if we perform our role without believing in it, but expecting that the audience will. But rather than being a neat spectrum from sincerity, through ambiguous sincerity, all the way to cynicism, Goffman argues that a performer will tend to one extreme or the other: either believing utterly in the role he is presenting, or presenting it totally without conviction for the benefit of the audience only.
Thinking on my own experience of being a Jehovah's Witnesses who developed doubts, and from observing others, I find this to be true. When I believed it was the truth I presented myself as a Witness with utter conviction in the role I was performing. As soon as I started to doubt in the belief system, all the actions of being a Witness lost their inner meaning for me: answering up, presenting magazines at the doors, conversation with other believers. I was suddenly aware of the enormous expectation to perform and signal according to standard Jehovah's Witness practice in order not to alarm those around me, and in order to appear coherent even if mentally I was confused and unsure. The accumulation of doubts was a gradual process; however the movement from performing the role of being a Jehovah's Witness shifted from a presentation based on conviction to one of inner cynicism very quickly, even while many doubts remained unresolved.
So if it is true that Jehovah's Witnesses who on an individual basis are each performing the outward signs of being a Jehovah's Witness can be divided into those who are 'presenting' with inner conviction and those who are 'performing' purely for the benefit of the audience, with little scope for anything between those two, then it makes observing the behaviour of other Witnesses all the more interesting, trying to figure out which camp the performance of each fellow believer comes under.
