Collective Information Sampling: Surface What Only One Person Knows

The group repeats what everyone knew

Collective Information Sampling explains why group discussion can repeatedly validate common knowledge while decision-critical evidence remains distributed across individual members

Premise

A team can collectively possess the evidence for a better decision and still never assemble it in conversation. Collective Information Sampling explains why: information known by several members has more opportunities to enter discussion than information held by only one. Shared facts are therefore more likely to be mentioned, repeated, confirmed, and treated as representative of what the group knows.

The executive problem is not simply participation. A meeting can be lively and inclusive while reconstructing only the common portion of the evidence. When the value of a committee depends on complementary expertise, the relevant question is whether discussion recovers distributed knowledge before preferences, status, and public commitments make the leading option harder to revise.
