  "summary": "A recommendation can be judged differently depending on who signs it. This means neither that expertise is incidental nor that a recognised signature guarantees better-grounded judgement.",

      "heading": "The premature conclusion",
      "point": "One might conclude that recommendations should simply be signed by the most recognised person available."

      "heading": "What the evidence cannot guarantee",
      "point": "The classic experiments do not reproduce an organisation’s lasting relationships, hierarchical dependencies or regulatory responsibilities."

      "heading": "A practical check in Lausanne",
      "point": "As part of SHR’s “Communication” programme, a Lausanne team could test a fictional recommendation with no operational consequences, randomly assigning participants to two otherwise identical versions: one gives the real author’s name and role, while the other adds their relevant, verifiable expertise."
