Country Methodology Media Bias Fact Check
Starting in 2025, we have a new methodology that aims to assess media outlets’ ideological bias and factual reliability systematically. It uses a comprehensive, weighted scoring system to evaluate political, social, and journalistic dimensions. This approach ensures an accurate and transparent assessment of a source’s political alignment and commitment to factual reporting, providing readers with a better understanding of media credibility and bias. (All reviewed and re-reviewed sources are subject to this methodology beginning Jan 1, 2025.) Bias is inherently subjective, and while no universally accepted scientific formula exists to measure it, our methodology uses objective indicators to approximate and represent bias. Each evaluated source is placed on a bias scale, visually represented by a yellow dot, to indicate its position.
This is complemented by a “Detailed Report” that explains the source’s characteristics and the reasoning behind its bias rating. While this updated methodology reduces the influence of a strictly U.S.-centric political spectrum, it remains primarily tailored to the political landscape of the United States. This ensures that evaluations are relevant to a significant audience while acknowledging that some biases in the U.S. context may not apply exactly in other countries where terms like “Liberal” may have a different meaning. Readers should consider this when comparing sources with political systems from other countries. For example, a left-leaning source looks like this:
A strongly right-leaning source looks like this: Media Bias/Fact Check (MBFC) is a long-running site that catalogs more than 3,900 media outlets and publishes daily fact-check compilations and bias ratings; MBFC says it uses a structured methodology updated in 2025 to...

Right Bias: How we rate the bias of media sources The data presented below reflects Media Bias/Fact Check’s (MBFC) longstanding commitment to objectively rating media sources based on factual reporting and political bias. All evaluations are conducted using a consistent and structured methodology developed to reduce subjective influence. The numbers in the table represent live totals that evolve as new sources are added or re-evaluated, but the principles behind those ratings remain constant. MBFC uses a composite scoring system that rates each source on a scale from −10 (Extreme Left) to +10 (Extreme Right). This score is derived from four weighted categories: Economic Policy (35%), Social Values (35%), Straight News Balance (15%), and Editorial Bias (15%).
The intent is to assess the ideological character of the content, not the publisher’s intent or ownership. Scores are based on actual content and sourcing, not affiliation. A left or right-leaning outlet is rated as such only when its output consistently reflects those leanings. Factual reporting is rated using a weighted formula based on four criteria: The average bias rating of +1.12 reflects a volume effect, not methodological bias. Several interconnected factors contribute to this outcome:
These sources have minimal bias and use very few loaded words (wording that attempts to influence an audience by using an appeal to emotion or stereotypes). The reporting is factual and usually sourced. These are the most credible media sources. See all Least Biased sources. Bias Rating: LEAST BIASED (-0.1) Factual Reporting: VERY HIGH (0.0) Country: USA MBFC’s Country Freedom Rank: MOSTLY FREE Media Type: Organization/Foundation Traffic/Popularity: High Traffic MBFC Credibility Rating: HIGH CREDIBILITY FactCheck.org is a nonprofit website that describes itself as a non-partisan “We are a nonpartisan, nonprofit “consumer advocate” for voters that aims to reduce the level of deception and confusion in U.S.
politics. We monitor the factual accuracy of what is said by major U.S. political players in the form of TV ads, debates, speeches, interviews and news releases. Our goal is to apply the best practices of both journalism and scholarship, and to increase public knowledge and understanding.” FactCheck.org has won multiple Webby Awards in the Politics category.

Major media-bias assessment projects and academic studies show that many mainstream outlets are often rated as center-left or “lean left,” but findings vary by method and country and are contested by other observers (see... Public perceptions of a leftward tilt are widespread—especially from conservative critics—but empirical studies and multi-perspective rating systems emphasize nuance: some mainstream reporting shows left-leaning patterns while commentary/opinion tends to be more partisan [4] [3]. 1. What the major bias charts actually say: placement, not proof
Media-mapping projects such as AllSides and Ad Fontes place many well-known outlets toward the center-left or “lean left” on their charts, based on panels, surveys, or multi-rater methodologies; AllSides says its ratings reflect a... These charts map perceived ideology and/or content patterns — they do not prove institutional intent or uniform bias across all reporters and stories [1] [7]. 2. Academic studies: evidence of leaning on some dimensions, but complexity reigns Use the drop-downs to sort our source ratings by Bias, Factual Reporting, Country of Origin, Traffic Estimates, and Credibility.
