“One of the great ironies of the fact-checking enterprise is that despite their mission to bring transparency and truth to the marketplace of ideas, fact checkers themselves operate largely as black boxes.

As Facebook’s financial influence over the fact-checking landscape grows, new questions arise about fact checkers’ financial transparency and external influences.”  – Real Clear Politics
