3 concepts from archive studies that every data journalist should know

Until last month I hadn’t heard of diplomatic studies. It’s the discipline of studying historical documents, and comes from the word ‘diploma’, as in ‘verifying that someone hasn’t faked their records’ (I’m paraphrasing here). But this discipline of verification has some useful lessons for journalists — particularly data journalists — because it provides a very handy framework for picking apart what makes a record (data) credible, and what we should be looking out for when establishing that.

Particularly useful are three terms that are used to distinguish different aspects of a record’s credibility: authenticity; reliability; and accuracy.

Ethics in data journalism: accuracy

This, says FSB, is a lie that demonstrates the “pretence” that “‘crunching the numbers’ is somehow an an abstract, scientific, mathematical task”. Continue reading

Complaint over attack on hyperlocal blog upheld by PCC

You may remember ‘investigation’ by The Hull Daily Mail into HU17.net, a hyperlocal publisher that was operating on its patch back in March, and the resulting backlash against the newspaper by observers who saw this as a commercially motivate hatchet job. Now the Press Complaints Commission has upheld a complaint on the basis “that readers would have been misled as to the scale of the complainant’s involvement in adult websites. The result was a breach of Clause 1 of the Editors’ Code.”
