The rewards and rules of human collaboration systems shape the behavior of the human participants, often leading to behaviors the human computation system designers never envisioned. Most software designers make the mistake of assuming that people will follow the intent of the rules they set up in the program.

People will do anything they can to achieve rewards, and sometimes the reward means breaking the system for the joy of figuring out how to solve a puzzle.
