Amity is the faction that dislikes war. Amity was formed in order to have a peaceful society free from conflict and sadness caused by wars and instigation. Amity doesn't recognize a leader, but use Johanna Reyes as their representative or "mouthpiece". They are a democratic faction, unanimously voting on almost everything. The bread that they eat even had a Peace Serum in it while other factions' members were present in Amity to prevent them from fighting. As the faction that symbolizes happiness and freedom from human conflict, Amity members generally wear clothing that is bright and pleasant. Their attire consists of clothes that are earthy shades of red and yellow. Their dress code is less formal than other factions and an Erudite-born Amity transfer could wear blue jeans without causing uproar. They occasionally also wear green or brown clothing. They generally wear loose skirts, pants, and shirts made of comfortable material. Girls generally wear their hair long and loose.

Amity people value peace and kindness as well as blame conflict and hatred for the world's problems. People of Amity value neutrality, so they remain neutral in times of war. In Amity, opposed to Candor, believe that is acceptable to lie in order to keep the peace. They believe that the down-fall of society was caused by violence.

Very little knowledge of Amity's initiation process is revealed in the books. What is known, though, is that it involves fruit-picking and singing songs. Like the other factions, Amity has their own serum. The factions serum relate to each other's beliefs, like how Candor has their Truth Serum. Amity has the Peace Serum, that puts its user in a friendly, cheerful state.
