This document discusses the concept of groupthink, which refers to how people work together in groups to solve problems. Groupthink can be either positive or negative. The creator Janis Irving defined it as a mode of thinking where a group prioritizes consensus over realistically evaluating alternatives. However, some research has also shown positive aspects when groups build on each other's ideas. For groupthink to be constructive, every group member must contribute to the open discussion without bias.
