For consumers of news from left-leaning viewpoints, the task of finding credible news can be difficult. While news on the right is increasingly restricted to a handful of sources, left-leaning outlets are numerous and varied. As a result, finding the best news to read is increasingly challenging. 

The allure of ad revenue incentivizes news sources to publish more frequently. But is good for publishers may not be good for the consumer. Finding well-researched, minimally biased, and credible articles is hard but essential for making daily choices. And everyone deserves the tools to do so.

At The Factual, we provide data to help readers identify the best news sources across the political spectrum. To do so, we built a dataset of over 828,000 articles, representing the (near) total publishing history of 54 major news sources and online publishers from January 1, 2020 to May 18, 2021. Then, we can measure which news sources consistently produce the most credible, highly researched news according to each outlet’s average Factual Grade. This week, we’ve used this dataset to highlight the top five left-leaning news outlets.

Where Is the New York Times?
You might be curious about how other major news outlets and key players in the progressive media landscape scored. In a nutshell, they score variably from fairly high to fairly low. Prominence in the media landscape does not seem to be correlated with article credibility, at least as measured by our metrics. CNBC scored 71.5%, the New York Times scored 68.4%, NPR scored 67.2%, the Washington Post scored 66.1%, and CNN scored 53.6%.

How Does The Factual Rank the News?

The Factual’s news-rating algorithm measures how objective (or factual) any news article is based on four metrics. Each answers simple questions about the quality of an article:

  • The number and diversity of links and meaningful quotes
    Does an article provide ample, diverse evidence? Does it include direct quotations? This metric helps capture whether an article is supported by facts.
  • The writing tone
    Is the article written to educate or infuriate? Is the writing strongly opinionated or trying to convey information? By using natural language processing, this metric can help identify objectivity and subjectivity.
  • The topical expertise of the author
    Has the author written on the topic (e.g., U.S. politics, homeland security, immigration) before? How have past articles by the same author scored? This helps measure whether the author has a reputation of producing credible news on a topic.
  • The article history of the publishing site
    How have other articles from the same source scored? Are they typically well researched? This tells us whether the publishing site has a record of producing quality journalism.

These four metrics make up the Factual Grade for each article. Articles that score 75% or higher are very likely to be credible. That means an article is well researched, written by an author with topical experience, is published by a reputable site, and is written in a neutral tone.
