"In a 2004 survey conducted by Pace University, the Post was rated the least-credible major news outlet in New York, and the only news outlet to receive more responses calling it "not credible" than credible (44% not credible to 39% credible).[65]
The Post commonly publishes news reports based entirely on reporting from other sources without independent corroboration. In January 2021, the paper forbade the use of CNN, MSNBC, The Washington Post, and The New York Times as sole sources for such stories.[66]"
