Alexios Mantzarlis at the journalism website Poynter.org reported "Conservative websites are far more likely to attack fact-checkers than their liberal counterparts." Something called the Duke Reporters' Lab issued a study of ten "partisan" websites and determined that the conservatives were much more hostile to the fact-checkers, while the liberals were overwhelmingly supportive. Mantzarlis took ten paragraphs to get to the important detail that the study's co-author was a founder of PolitiFact.
