The golden thread for this option, step by step. A dashed step is missing — shown as a gap, never filled in. Provisional single-reviewer assessment; not an approved business case, and not government policy.

  1. Step 1: Topic headlineIn place

    Media

    Almost six in ten under-35s get most of their political news from social media. Among over-55s, fewer than one in twelve do.

    Priority: Support reliable news, a range of voices and accountability while protecting freedom of expression. What would change it →

  3. Step 3: EvidencePartly in place

    Outcome: Exposure, wellbeing and attitudes, alongside expression and privacy outcomes.

    Artifact cites platform experiments but mixed attitude effects; UK wellbeing benefit and transfer are not established.

    A proposed action with a sourced problem and a follow-up appraisal design. This does not establish the effect or whole-life cost of the intervention.

    What the evidence supports—and the next decision

    Feed exposure and harm are not interchangeable measures. The net effect of a particular amplification control remains design-dependent.

    AI-assisted analytical follow-up · 8 October 2026. Proposed appraisal design; the attributed scores below are unchanged. No funding or delivery agreement is implied.

    Define the change
    Specify one recommender-system change and eligible content, with independent access to an auditable test and comparison condition.
    Test whether it works
    Exposure to the defined harm, user wellbeing and unintended suppression, with age-specific measures. Engagement is not a wellbeing outcome.
    Establish the cost
    Engineering, researcher access, audits, enforcement and appeals; separate a pilot from continuing regulation.
    Protect against harm
    Protect privacy, expression and lawful content. Publish false-positive and appeal outcomes; no broad censorship score follows from a reach statistic.

    Read with the outcome evidence and sources in the full assessment. Monitoring proposals are not existing baseline measurements. A numerical benefit or cost score needs evidence for the defined increment, not just the scale of the problem.

    Full assessment of Controls on what feeds amplify: ten criteria, scenarios, delivery, costs and monitoring

    The ten criteria (0–3)

    Each criterion is scored 0 to 3 by the reviewer. “Not yet assessed” means unknown: it is never counted as zero.

    1. Scale and severity (Sc)2 of 3 — Serious harm to a defined group or widespread moderate harm

      Reviewer’s reason: Provisional problem-importance judgement from linked site pages; not the scale of achievable benefit.

    2. Increment beyond baseline (Ad)2 of 3 — Specific material change to existing delivery

      Reviewer’s reason: Specify ranking intervention and trial agreement; independent researcher access, consent/privacy safeguards and meaningful outcomes; separate later regulation. A missing rating requires a defined marginal change.

    3. Confidence in the proposed action (Ev)1 of 3 — Indirect, mixed, modelled or weak causal support

      Reviewer’s reason: Artifact cites platform experiments but mixed attitude effects; UK wellbeing benefit and transfer are not established.

    4. Expected incremental benefit (Bn)Not yet assessed

      Reviewer’s reason: Unknown unless a reasonably defined target-population benefit can be judged; no bonus merely for spanning domains.

    5. Residual harms (Hm)1 of 3 — Material harm/unresolved mitigation

      Reviewer’s reason: Expression/privacy risks; unintended engagement and exposure effects.

    6. Incremental affordability (Co)Not yet assessed

      Reviewer’s reason: Platform engineering, independent research, auditing, enforcement and compliance; a cheap pilot is not a costed regulatory system.

    7. Delivery capacity (Ca)2 of 3 — Stretched but plausibly obtainable

      Reviewer’s reason: Specify ranking intervention and trial agreement; independent researcher access, consent/privacy safeguards and meaningful outcomes; separate later regulation.

    8. Distribution (Fa)2 of 3 — Mixed or broadly neutral with safeguards

      Reviewer’s reason: Provisional distribution judgement for the stated target; verify who pays, who gains and excluded groups.

    9. Meaningful first outcome (Ti)2 of 3 — More than one and up to three years

      Reviewer’s reason: First meaningful outcome, not announcement: Exposure, wellbeing and attitudes, alongside expression and privacy outcomes.

    10. Readiness (Rd)2 of 3 — Named commissioning/allocation/coordination step

      Reviewer’s reason: Researchers, platforms and regulators; government/Parliament for legal changes; UK mechanism and outcome study

    Four weightings

    Normalised as 10 × weighted sum ÷ sum of weights, on a 0–30 scale. Where a criterion is not yet assessed, the range is the lowest and highest result if it were later scored 0 or 3 — not a score, a confidence interval or a rank.

    • Equal weights: Range if completed: 14.0–20.0 out of 30. Not yet assessed: expected incremental benefit (Bn), incremental affordability (Co). Funding gate: not passed.
    • Evidence doubled: Range if completed: 13.6–19.1 out of 30. Not yet assessed: expected incremental benefit (Bn), incremental affordability (Co). Funding gate: not passed.
    • Scale doubled: Range if completed: 14.5–20.0 out of 30. Not yet assessed: expected incremental benefit (Bn), incremental affordability (Co). Funding gate: not passed.
    • Cost ignored (the funding gate still applies): Range if completed: 15.6–18.9 out of 30. Not yet assessed: expected incremental benefit (Bn), incremental affordability (Co). Funding gate: not passed.

    Funding gate: Not passed — the cost is not yet assessed or no allocation is committed for this scope. Ignoring cost in a weighting never removes the gate.

    Delivery risk and gate

    Delivery risk shown: AmberReview’s claim: Amber. Best the recorded evidence allows: Amber.

    Review’s reason: Platform engineering, independent research, auditing, enforcement and compliance; a cheap pilot is not a costed regulatory system.

    Why it is not Green yet

    • Scope (population, place and increment) not verified against the delivery baseline.
    • No verified owner with the powers in place.
    • Delivery capacity not verified.
    • Lifetime incremental costs not complete.
    • No credible funding (a committed allocation for the scope).
    • Safeguards not specified.
    • Monitoring lacks a metric, a data source or a baseline.

    Green needs verified scope, a verified owner with the powers, verified capacity, complete lifetime costs with credible funding, specified safeguards and monitoring with a metric, source and baseline. Amber means appraisal gaps remain; Red means a material delivery obstacle. Red does not mean unimportant.

    Gate: Pending — appraisal incomplete (review label: “Pending: incomplete appraisal”).

    Why: Scores incomplete; Funding gate not passed (cost unknown or no credible funding).

    The gate is separate from national list membership: being listed does not make an option eligible, and an eligible option need not be listed.

    Cost and funding

    Lifetime costing: Not established. Review: “Full incremental costing not established in reviewed material”.

    Still to cost: Platform engineering, independent research, auditing, enforcement and compliance; a cheap pilot is not a costed regulatory system.

    Funding status: not established in review.

    Owner, powers and capacity

    Proposed owner: Researchers, platforms and regulators; government/Parliament for legal changes (proposed, unverified).

    Powers: needs a decision or allocation. Capacity: unverified.

    Powers and capacity read from the review’s Rd and Ca anchors; no proposed owner has agreed to act (the review: “Proposed owners have not agreed to act”).

    Evidence for the outcome

    Review record

    Assessment status: Provisional single-reviewer assessment; not an approved business case.

    Reviewer: Original assessment author (name not supplied). Reviewed: 6 October 2026.

    Scored in the working review of 6 October 2026 on the shared ten-criterion scale (one reviewer); not independently calibrated.

    First 90 days (review): Produce a signed scope and current-delivery baseline; Specify ranking intervention and trial agreement; independent researcher access, consent/privacy safeguards and meaningful outcomes; separate later regulation. Obtain incremental costs and an accountable decision before expansion.

    Decision route: UK mechanism and outcome study

    An editorial screening framework by one reviewer, not a formal appraisal or business case. Proposed owners have not agreed to act.
