Use in the Aptitude Test
For the non-Divergent it will be almost like a dream, where they act on impulse rather than rationality. It determines the child's most predominant characteristics: bravery, selflessness, peacefulness, honesty or intelligence. For those with Divergence, they will be in a conscious-like state. The Simulation will appear more like lucid dreaming, where they are in control and can think things through. The Genetically Pure will more likely than not have more than one result from the test and does not fit into just one category. It also means that they are able to withstand some of the other serums.
The initiates are expected to choose according to their test results, but are allowed to make their own choice at the Choosing Ceremony.
For the serum to work, it needs to be consumed. For the Aptitude Test the serum is taken orally instead of injected. The one taking the test is connected to the Administrator from a different Faction by electrodes to both their foreheads. The Administrator can change the scenarios the other is experiencing. In Tris Prior's case, Tori changed the Simulation to be on the bus, so she could eliminate Candor. [
In theory, there are five different results from the test:
- Abnegation: the selfless,
- Dauntless: the brave,
- Amity: the peaceful,
- Candor: the honest,
- and Erudite: the intelligent.
However, it is also possible to qualify equally for more than one(usually two). This is called 'Divergent'. Tris is the only know case of qualifying equally for three factions, who showed an aptitude for Abnegation, Dauntless and Erudite.
