The main idea here is how group participation boosts the amount of information available for a decision. When many people contribute, they bring different facts, experiences, and sources to the table. That collective input creates a larger pool of information, so the group can accumulate more data points, verify details through cross-checking, and identify gaps or biases that a single person might miss. This information accumulation builds a stronger, more comprehensive evidence base to bases the decision on.

Knowledge diversity helps by bringing varied expertise, which supports gathering broader types of information, but the specific advantage tied to information gathering is the overall accumulation of information as the group combines inputs. Better understanding of the decision rationale and deeper commitment to the decision are valuable outcomes of group discussion as well, but they relate more to why the group chose something and how committed members are, rather than the act of gathering and compiling information.
