I am not presenting this as directly relevant, or with an specific angle on the JW issue, so much as just on it's own merits as a really great take on phenomenon of social conformity:

"We can be self defeating in our conformity: Say we have a group of people holding opinion X. Unbeknownst to the group, half of them secretly disagree. But, due to the social penalties dished out to a few individuals who have disagreed, they keep quiet. By conforming, we add to the statistics of groups we don't actually belong to, and perpetuate the idea of majorities who may not actually exist."
