About
Why this exists
Microbiome science is one of the most over-claimed areas in popular health writing. The underlying research is genuinely fascinating — bacteria really do signal, cooperate, cheat, hold territory and travel between people — and it is routinely stretched into things the data does not support.
Small Talk is an attempt to hold both at once: take the social parallels seriously, and be relentlessly explicit about the difference between what is established, what is emerging, what is contested, and what nobody knows.
How a claim gets here
- 01
Papers come in
Saved searches run against open scientific literature databases and surface new work matching each theme. Nothing enters the library automatically — a curator reads and rates it first.
- 02
Everything gets a plain summary
Each paper is rewritten in ordinary language, with the study type stated up front so you can weigh a review differently from a rat experiment differently from a large human cohort.
- 03
Claims are rated, not asserted
A claim only appears once it is tied to specific papers and given a confidence label. Where the popular version overshoots the data, the caveat says so directly.
- 04
Gaps are published on purpose
When the evidence runs out, that becomes an entry on the Open Gaps page rather than a silence. Each gap names what study would close it.
- 05
Citizen input is reviewed, then labelled
Public contributions are read by a human before publication and are always shown as personal accounts — never mixed in with peer-reviewed evidence.
The confidence labels
- Well established
- Repeatedly demonstrated, with agreement across independent groups.
- Emerging
- Real evidence exists, but it is early, limited, or not yet replicated widely.
- Contested
- Studies disagree, or the popular version of the claim runs ahead of the data.
- Not yet known
- Open question. Nobody has answered this properly yet.
What this is not
- Not medical advice, and not a substitute for a clinician.
- Not a product recommendation. We do not sell or endorse probiotics or tests.
- Not a claim that human relationships are reducible to bacteria. The parallels are a way in, not a theory of people.
