krysssjekking

Kryssjekking, ofte written kryssjekk or cross-checking in English, is a method for verifying information, data, or claims by comparing them with independent sources, alternative calculations, or different methods. The aim is to confirm accuracy and reduce the risk of errors or misinformation.

The term is widely used across fields such as journalism, science, finance, and quality assurance. In journalism, kryssjekking involves corroborating statements, dates, and quotes with multiple sources before publication. In research, it can take the form of data triangulation, replication of experiments, or cross-validation of results. In business and administration, it includes reconciliations between financial records, inventories, or system logs to ensure consistency.

Common methods include triangulation (using more than one source or method), data reconciliation, replication of procedures, and independent review. The process typically involves collecting relevant sources, comparing them for consistency, investigating and resolving discrepancies, and documenting the conclusions and any limitations.

Benefits of kryssjekking include increased reliability, reduced errors, and greater trust in information and decisions. Challenges can include time and resource requirements, access to independent sources, potential contradictions among sources, and the need to decide how to handle unresolved discrepancies.
