Use in Aptitude TestsEdit
In the Aptitude Tests, simulations are used to determine a child's predominant characteristics. The results are an indicator of which faction the child should choose. Test results of the Divergent are inconclusive.
The Simulation Serum is usually administered orally in liquid form for the Aptitude Tests, however, it can be injected in a vaccine-like manner if need be.
One version of the simulation is to choose between a knife and a piece of cheese. The Dauntless choose the knife, while the Amity choose the cheese. However, it is also possible to refuse both, as in a persons case, after which she submitted to the dog that occurred with an Erudite response. A child appeared, and the dog ran at her. Tris threw herself at the dog - a Dauntless and Abnegation response.
There are other scenarios in the simulation too, like cats clawing your eyes out-or something like that.
Use in Dauntless InitiationEdit
The Simulation Serum is used in the emotional stage of the Dauntless initiation.It was also used for the fear landscape test.
The initiates are given a serum shot containing a transmitter that sends the data to a computer and connects the mind to the simulation.
