Minecraft wiki entry for Villager, associated text: Villagers can store certain memories about players in the form of gossip. These get spread to other villagers whenever they talk with each other. Each piece of gossip is one of five types, and it stores a value as well as a target. Gossips generate and increase in value as a result of various player actions. The target is the player who caused the gossip. Together the gossip values determine a player's reputation with the villager, which influence trading prices and the hostility of naturally spawned iron golems.
