The Computer decided that sex and birth were very inefficient methods of creating citizens. Instead, Alpha Complex produces all of its loyal citizens in clone vats. Six citizens are produced at once, all identical. When If a citizen dies, their next clone is sent by means of a rapid replacement system. In practice, this normally means that a replacement clone turns up within five minutes of The Computer being notified of the death of the previous one.

Despite any evidence to the contrary, everybody believes that a replacement clone is free of any deformities that the previous one may have had (be this a mutation, secret society membership or knowledge of what's really going on). To point out to The Computer that two clones from the same batch have mutations is a bad idea unless you have very good evidence to back this claim up. The Computer doesn't make that kind of mistake.
