Martian Culture:
Martians are grown in artificial wombs. Originally they were grown from refrigerated gametes brought from Earth, but later methods use binary cloning techniques, as they don't require both a male and a female donor, and they are easier to create.
Six months after removal from the Artificial Womb children are divided into five groups based on physical and mental abilities. Those with severely sub-par mental capacity are placed in Tier one. Those with far above average mental capacity are placed in Tier five. The other three tiers are those with near standard mental and physical abilities. Children are then given ANCIs based on their tier, with Tier one receiving cheap, easy to produce ANCIs on par with free government ones on Earth, and Tier fives are receive Organic ANCIs from the best doctors on the planet. They then begin their training.
At the age of six they are divided into ten different groups based on a more detailed assessment of their abilities and receive basic education based on those groups. This is known as core training. At the age of fourteen they choose a specialty that is a part of their group and begin specialty training, similar to college. At the age sixteen they begin on-the-job training as their job, instead of the menial jobs they've been doing practically interchangeably sense the age of ten. At the age of eighteen they finish their specialty training and apprenticeship and apply for one or more of the available jobs that match their specialty or, in rare occasions, their core training. They work at that job until they are fired, find a job where they are needed more, or they are unable to perform it. They then get a new job. Rarely people receive permission to start a new business, and they can then hire people to perform a newly needed role in society.
Even in such a closely regulated society, there is individuality. In fact, people are encouraged to be themselves as long as it doesn't jeopardize the colony or others. As such, all people are sterilized at birth. Should a pregnancy still occur (extremely rare) the child is taken into the raising program and is incorporated into it as the other children are. They are never told who their parents are, as it doesn't matter. Gene sequencing can take care of any medical uses for such knowledge, and incest is meaningless outside of the cloning/birthing facility.
Tier one people generally perform the low-grade physical labor and maintenance that robots aren't worth using for. This includes driving rovers, overseeing automated processes and alerting the other maintenance crew of breakdowns, and other times that adaptability beyond that of a robot is necessary. Tier one positions are slowly being phased out as better cloning and breeding methods are discovered. As of 2064 all Tier 1 positions are filled by people with IQs below 70.
Tier two are the positions that require a low amount of intelligence. They are generally taken up by those with an IQ between 70 and 90. These roles include overseeing the robots and adjusting which programs they execute, simple maintenance that robots can't adapt to, like unseen problems with machinery, and the like.
Tier three positions are typically filled by people with an IQ between 90 and 120. They write the programs the Tier 2 people put into the robots, build the more complex devices which require intuition, like mid-grade and above ANCIs, and basic supervisory roles of the lower three Tiers.
Tier four positions are generally research and/or art related. They are nurses, Doctors, artists, structural engineers, and basic researchers. They generally have an IQ between 120 and 150 and oversee themselves.
Tier four positions are the serious researchers and theoretical scientists. They lay the groundwork for the inventions of the Tier fours. They are also artists and architects. Many pilots also fall under Tier 5, though pilots can come from any of the upper four tiers. This is because people in Tier 5 have the mental abilities to control the complex controls of the more advanced crafts. Physical abilities are virtually meaningless to most Tier Five positions, so physical training isn't stressed during core training. Tier 5 people tend to have IQs above 150.
