When you hear left-leaning news, you may think CNN, The New York Times, or The Washington Post. While these large media sources produce a large volume of stories, are they actually the most credible left-leaning sources?
In an increasingly saturated and liberal-leaning news space, readers are faced with the challenge of cutting through the noise and simultaneously forming their own opinions. With over 320 left-leaning news outlets, parsing through that amount of information seems a nearly impossible task.
To make the search for credible news easier, we used our algorithm to find the highest-ranking liberal news sites, to follow up from our previous analysis of the highest-ranking conservative news sites.
The Factual’s algorithm analyzes individual articles for credibility based on the author’s topical expertise, the diversity of sources via links and quotes, the neutrality of the writing tone, and the historical reputation of the publishing site. The average credibility rating of a news source accounts for all of the articles produced during that time period. Articles rated over 75% have a high confidence of credibility. To learn more, see How It Works.
We analyzed 58,000 articles published between May 1 and May 21 and curated top 10 left-leaning sources that have posted at least twenty times within that period. To find a list of all left-leaning sources we analyzed and their ratings, see appendix.
Here is the breakdown of the top 10 publications based on their average Factual credibility grade:

What does this data mean? We were surprised to find that most of the big name left-leaning sources did not make the top 10. The New York Times scored 69%, CNN, the most popular left-leaning source, scored 54%, and BBC scored 66% — putting them below the niche outlets featured in this list. This begs the question of quantity versus quality when it comes to reporting, as smaller sites often feature expert analysis that takes longer to curate, resulting in less frequent articles. For example, on the topic of civil liberties, The Intercept scores consistently higher than The New York Times, and on matters concerning elections, FiveThirtyEight leads the discussion. In this way, our algorithm serves as a proxy for expertise, as niche sites often have an extensive history of writing on a topic with well-researched articles.
Across the aisle, popular right-leaning publications such as Fox News or the Wall Street Journal have an average credibility grade of 57% and 66% respectively, which would also put them below the top 10 here. Does this mean that left-leaning sites are more credible? Not necessarily. While Fox News and the Wall Street Journal may be the biggest names on the Right, we discovered that there are many niche right-leaning sources that are just as credible as the publications listed above, including Reason and Military Times.
This indicates that, regardless of political leaning, news sources dedicated to a certain topic rate more highly than high-volume, general news sources, as they tend to provide more well-researched context.
At The Factual, we hope to use sound methodology and direct our readers to quality news across the political spectrum. This way, individuals can sift through the information and make better-informed decisions in light of the constantly changing world around us. We fundamentally believe that including a variety of perspectives is a key component to acknowledging and accounting for the implicit bias from both authors and readers. We hope this list of sources encourages our readers to consider diverse outlets in their search for the truth.
Lastly, we know that finding multiple credible perspectives on every topic, every day, can be exhausting. That’s why The Factual’s mission is to apply its algorithm to the 10,000+ articles published every day, cultivating the most credible stories on the hottest topics across the political spectrum in our daily newsletter.

Appendix: Left-leaning sources analyzed and their average credibility scores.
Note: We removed sources with less than 20 articles published during this time period, since there was not enough data to make an accurate representation of their average score. Also, some outlets are behind a paywall which makes it difficult to access all their articles to analyze.
