Journalism Historian on 1852 NY Tribune Integrity for Podcast

Historical question about journalistic integrity I have a podcast that I'm doing some research for. It's small and sad, but it's mine and I'm proud of it. Most of the time. Anyway, I'm working on a story that references an article in the New York Tribune from 1852. At the time, Horace Greeley was the editor. Everything I've read suggests that Greeley was a good guy in general, and an aboveboard editor and journalist. That being said, what are the chances that an article could have been printed in the Tribune that was pure fabrication for the purpose of sensationalism and sales? Thank you in advance!
