The Global Disinformation Index is the world's first rating of the media sites based on the risk of the outlet carrying disinformation. We offer metrics and ratings - using both automated and human review - which provide a neutral and transparent way of assessing the disinformation risk for a specific media outlet. We operate on three core principles of neutrality, independence and transparency. Neutrality: The GDI is non-political. The governing board consists of independent trustees with no commercial links to the media. Our Advisory Panel consists of international experts in disinformation, indices and technology. Independence: The GDI is a UK not-for-profit organisation. Our funding comes from a range of sources including governmental, philanthropic and from companies. No single funding source is to make up more than 33% of the total funding base. Transparency: Our index methodology is published, and we will include the scores behind the ratings of all news domains rated. Our funders is continually updated online. We are cross sector of disinformation, artificial intelligence (AI) and measurement experts from around the world. Our work provides needed metrics to help governments, advertisers, media, digital media and the public understand the disinformation risks of news sites.
