The only way to create a true counter weight is the amount of time encompassing the false hood should be the same amount of time given to the retraction. 1 day of false hood should equal 1 day of retraction.
Will this mode of operation exist, most likely not. The closest the USA had to such would be the Fairness Doctrine. [0]
The NYT intentionally runs stories that are highly dubious or they know to be false, then later issue a small retraction in a footnote.
The latest fake news they published was the story around Zohran Mamdani where they used hacked data from Colombia University to claim he checked "black" on the admission documents to gain an unfair advantage. That's because they are partisan hacks. I don't necessarily like Zohran, but he represented a threat to mainstream Democrats therefore the NYT had to do something about him.
I saw a similar theme in right-wing American propaganda wherein American conservatives know that their media is biased, but they assume that "mainstream media" is just as bad.
It seems like in all of these cases, propagandists aren't trying to get people to believe the propaganda, but rather to discredit the entire idea of objective facts or reliable reporting.
