What type of person might not “fit in” to a carefully planned and organized community and selected 12 as the age for transitioning into adulthood?

This question calls for your opinion. In order to fit into the community, a twelve would have to completely accept the Elders' decision for their career, their future spouse, and choosing their children. There are no choices, no options..... the twelves receive assignments, and there is no recourse. Thus, a twelve who is artistic, independent, and outspoken likely wouldn't fit in. Can you think of any other reasons.
