Contribution to the handbook
Supporting · Assessed 2026-10-28
The question offers a concrete algorithmic design possibility and the evidence identifies possible risks of ranking, while qualifying claims about polarization and reporting limited study detail. Its focus is social-media feeds rather than governance functions, so it is useful context rather than central system specification on this record.
Does this challenge the goal?
None identified
The question explores a possible way to shape social-media attention. It does not contest the handbook’s goal, and the definition does not prescribe a particular information or feed mechanism.
The evidence describes proposed designs and qualified concerns; it does not establish the effects of a bridging feed on public deliberation.
Why this category?
- Presents a specific possible mechanism for shaping attention across communities
- Supplies relevant but qualified risks and evidence limits
- The supplied material does not establish a direct governance-system application or effectiveness
The reported study effect is not described in enough detail here to assess its strength or generality; proposed bridging-feed effects remain hypothetical.
This is an AI assessment of contribution to the goal, separate from whether the question has an answer.

Read the exploration goalNew evidence is being assessed. Any answer below is provisional; parts whose evidence changed or was withdrawn are withheld.
Explain how attention or recommendations might change if feeds favored content that bridges different communities, without claiming the proposed approach is already effective.
What we can say so far
The authors propose using cross-community support to influence what receives attention: a feed could highlight content shared across several communities a person belongs to, and prioritize content supported by people with different views rather than a single like-minded group. This could make shared perspectives and context more visible than a feed focused on engagement or existing views. It is a proposed mechanism, not a demonstrated effect.
What remains open
- The material does not establish that this approach would broaden exposure overall or improve discussion.
- It does not explain how the proposed selection would handle inaccurate or harmful content.
- A reported study about exploration under Community Notes does not establish effects of the proposed feed-selection approach.
Conditions and limits
- The described feed changes are hypothetical; the material does not establish their effects.
- Which communities a person belongs to, and how the system uses that information, could affect what is recommended.
Objections to consider
- The source identifies a material risk that ranking can narrow what people see. The supplied evidence does not show whether bridging-based selection would prevent or offset that risk.

Bridging communities in social feeds The authors propose adapting Community Notes to map multiple communities and use a bridging approach to help choose which social media content receives attention. They say this approach could work at many scales and across intersecting groups, not only across a platform as a whole.
