I think it's a lot more reasonable to expect change journalism. Or maybe not journalism per se, but information dissemination/world model updates. News/journalism is just the form we've sort of settled on for that kind of job, but it's fundamentally the wrong thing. It's like asking for a faster horse when we want a car. Or asking for email notifications when we really want is a way to know the current status of something.
> Media literacy in that context would just refer to reliable sourcing, reliable sources post retractions/corrections.
I think the reach of those corrections is as much a problem as if they are published. Posting retractions to a printer that is directly hooked up to a shredder is technically "posting retractions", but practically it's not. Same as most news sources really. The retractions are functionally buried for almost all sources, including the most prestigious source Nature.
