Reading a source does not mean looking for a sentence that confirms a position. For Decido, the useful work is slower: who produced the information, what question it answers, which limits it declares and how it can be translated into everyday criteria.
This matters because many food, material and textile topics sit between incomplete data, regulatory decisions and scientific results that are not always final.
Primary sources first
When possible, we start from regulations, public authority opinions, scientific papers and technical documents. Journalistic summaries can help orientation, but they are not enough to explain dose, exposure, scope and uncertainty.
An EFSA opinion, an EU regulation and a WHO guideline may answer different questions. Substance safety, usefulness of a behavior and accuracy of a claim are separate layers.
Correlation, causality and context
An observational study may find useful associations, but it does not automatically prove causation. An experimental study may control variables better, but still have small samples or conditions far from everyday use.
That is why we avoid shortcuts such as “a study proves”. Better questions are: who was studied, at what dose, for how long, how large was the effect and do other studies point the same way?
Regulation is not a shortcut
An authorised ingredient is not a promise of irrelevance. A regulatory limit is not an individual diagnosis. A ban in one region may depend on new evidence, precautionary choices or different legal frameworks.
The honest work is to separate what the source says from what it would be convenient for it to say.
Reading checklist
- Identify author, date and type of source.
- Clarify the question: safety, exposure, labelling, claims or usefulness.
- Separate hazard, risk, dose and frequency.
- Look for declared uncertainty and limitations.
- Turn evidence into practical criteria without making prescriptions.
Conclusion
The method does not make every choice perfect. It prevents overly simple answers. Decido aims to open the sources, show context and leave the final judgement to the person.
