Summarise Research on a Scientific Topic for a Curious Layperson

The popular articles all say something slightly different and none of them cite anything. This summarises the research on a topic for you, separating what's well-established from what's still preliminary, so you understand the evidence rather than the spin. For people who want the real state of play without a journals subscription.

2. What the evidence currently shows (with a confidence level: established, emerging, or contested)
3. What is not yet known and where the active debate is
4. One practical implication for an ordinary person, calibrated to the evidence quality
