- Groupthink
- T3 — Information pooling failure: shared-information bias vs. dissent suppression.
This sourceDocuments the hidden-profile / biased-sampling problem — discussion is dominated by commonly held information while uniquely held information is under-shared.
Supported in partVerified against the publisher's abstract
The abstract states the biased-sampling model outright: discussion is dominated by commonly held information, so groups fail to pool unshared information; it never mentions dissent suppression or conformity.
“The proposed biased sampling model of group discussion, however, suggests that group members often fail to effectively pool their information because discussion tends to be dominated by (a) information that members hold in common before discussion and (b) information that supports members' existent preferences.”

Mechanisms¶
- Evidence Briefing Packet
- … most valuable when a group's disagreements are partly factual and would otherwise be settled by rhetoric, and when levelling the base changes who wins — it directly counters the hidden-profile problem, where groups over-discuss what everyone already knows and neglect the decisive information only one person holds.
This sourceShows that shared information dominates discussion, unique decisive information is neglected, and complete information can change the favored alternative.

- Its strength is that it counters the hidden-profile problem
This sourceShows that group discussion overweights information already shared by all members and often fails to pool uniquely held facts needed for the best decision.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 3 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
