What is it called when a group reaches a broad agreement during brainstorming?

The term used when a group reaches a broad agreement during brainstorming is known as consensus. Consensus refers to a collective decision-making process where all members involved express their opinions and work towards an agreement that everyone can support or at least accept. This approach emphasizes collaboration and inclusiveness, ensuring that every participant feels heard, and fosters a sense of shared ownership over the final decision.

While collaboration involves working together to achieve a common goal and can lead to consensus, it does not necessarily guarantee that a broad agreement has been reached. Negotiation typically involves discussing and bargaining to resolve differences and may not always lead to unanimous support. Deliberation suggests a careful consideration of different viewpoints but may not explicitly result in a unified agreement among all members. Thus, among these options, consensus is the most accurate term to describe a situation where a group has successfully reached a broad agreement during a brainstorming session.
