Accuracy and Evidence
We do not publish information simply because it is already circulating in the media, on social networks, or among individuals. Every significant claim must have a verified basis.
Decoder investigates issues of public importance, collects, verifies, and analyzes information, establishes facts, exposes abuses, and explains complex processes in clear language.
Evidence, independence, and accountability are at the core of our work.
Work on an investigation begins with monitoring processes and events, analyzing open data, decisions by authorities, public procurement, registries, court records, and other sources of public interest.
To establish the circumstances, we use primary sources, official documents, open registries, responses to information requests, interviews, and publicly available data.
Information on its own is not yet proof of our conclusions. We compare data from different sources, establish chronology, verify links, and separate confirmed facts from assumptions.
Before publication, information is carefully checked. We assess the origin and reliability of sources and whether the information can be independently verified.
Our findings are based on a combination of verified facts. We aim to show what each conclusion is based on and provide readers with enough context to evaluate it.
Before publishing material, we contact the people and organizations directly affected by significant claims or conclusions and give them an opportunity to comment.
