Preserved
The item has an identifiable source and enough original context to recover what was actually said.
Promising ideas deserve investigation. They do not deserve stronger labels than the evidence can support.
TerraEvidence records what was reported, how it was measured, where it may apply, what contradicts it, and what remains unknown. Interest can choose the next question; it cannot choose the answer.
A directly verifiable detail, such as the wording, value, unit, method, date, location, organism, or condition stated in a source.
Something seen or measured in a defined setting. An observation may be accurate without establishing its cause or generality.
A proposed explanation or prediction that remains open to testing, competing explanations, revision, and rejection.
A calculated or inferred quantity whose assumptions, inputs, range, and uncertainty must remain attached.
An action judgment that may require evidence beyond the underlying observation, including local conditions, benefits, costs, safety, regulation, and qualified professional guidance.
Preserve the original wording, source, date, and link without silently strengthening the claim.
Mark the material as fact, observation, hypothesis, estimate, recommendation, or unresolved combination.
Record place, country, climate, soil or medium, organism, treatment, method, comparison, timing, and measurement conditions when available.
Look for independent evidence, appropriate controls, comparable methods, repeat findings, limitations, null results, and contradictions.
Use a visible label that reflects the review completed—not the importance or excitement of the idea.
Release only material that is useful at its current evidence status. Keep raw recovery separate from public conclusions.
Make sources and limits visible enough that a reader can identify an error, missing condition, or conflicting result.
Update the conclusion or status when better evidence arrives. Preserve meaningful contradictions instead of erasing them.
A status is a record of what has been checked so far. It is not a guarantee that a claim will never change.
The item has an identifiable source and enough original context to recover what was actually said.
The idea may be useful, but sourcing, method comparison, contradiction review, or scientific interpretation is incomplete.
The item has been checked for wording, source traceability, method context, limits, and fit with the conclusion presented. Reviewed does not mean universally proven.
Not every source reports every field. Missing information remains marked as missing rather than being guessed.
Conflicting results can reveal hidden differences in soil, climate, organisms, doses, timing, methods, endpoints, or experimental design. TerraEvidence does not force unlike findings into a false average or select only the result that supports a preferred story.
Record the scope and evidence status of each result before trying to reconcile them.
Ask whether the studies measured the same property with compatible methods, units, treatments, and conditions.
Soil texture, pH, climate, crop, microbial community, dose, timing, and management history may change the response.
“The evidence conflicts” is more useful than a confident conclusion built by hiding uncertainty.
