How ‘triangulating’ can help you identify more sources

Triangulating journalistic sources: diagram showing that each of the three types of sources (people, data and documents) leads to the other two types of sources

In this edited extract from the forthcoming third edition of the Online Journalism Handbook I look at how a ‘triangulation’ approach to sourcing can help broaden story research and improve reporting.

Two centuries ago journalists were called reporters because they drew their information from official reports — documents.

Then in the late 19th century a new source became part of journalistic practice: people, as interviews and eyewitness accounts were added to news articles. 

The late 20th century saw reporting undergo another expansion in sourcing, as digital data was added to the journalist’s toolkit.

Although reports had included tables and other sources of data, the properties of digital data — filterable, sortable and searchable — have been significant, and make data a qualitatively different type of source.

How documents, people and data all lead to each other

Considering sourcing along those three dimensions — people, documents, and data — can be particularly useful when planning sourcing.

Defending an investigation — and planning one: lessons from ProPublica’s Black Snow

Sugar Companies Said Our Investigation Is Flawed and Biased. Let’s Dive Into Why That’s Not the Case.

The story itself, Black Snow, is an inspiring example of scrollytelling — but equally instructive is the methodology article which accompanies it, responding to criticisms from the sugar industry.

Not only does it demonstrate how to respond when large organisations attack a piece of journalism — it also provides a great lesson on the tactics that are adopted by organisations when attacking data-driven stories.

In this post I want to break down the three most common attack tactics, how ProPublica deal with two of those, and how to use the same tactics during planning to ensure your project design isn’t flawed.

What Data Journalists Need to Know About Application Programming Interfaces (APIs)

A list of APIs on the Parliament website
The UK Parliament publishes a series of APIs for political data

I’ve written a post for the Global Investigative Journalism Network about how APIs can be useful sources of data for journalists. The article is based on an earlier video post.

The article explains what APIs are and how they differ from other data sources; the basic principles of how they work and how they can be used for stories; some of the jargon to expect — and where to find them. Read the article here.
