- Where we observed it: The strongest current observations come from Participatory Methods; aggregators are listed as additional observations, not origin proof. (1 source observed, including Participatory Methods.)
- What that means: we track where an exercise has been observed in public sources. We do not claim to know who created it, or how popular it is.
- No efficacy claims: appearing in this library is not a claim that the exercise is proven effective. Facilitator judgment and context decide whether it works for a given room.
- Corrections: if you have evidence of an earlier or more accurate source, read our methodology and trust boundary and tell us.
