A basic observation about the internet is that there are differing accuracy standards in different contexts. For example, the accuracy standards of a newspaper are supposed to be higher than that of a “hot take”. This here blog has standards somewhere in the middle. I’m not speaking extemporaneously, so I’m expected to do some fact checking. But I’m also not paid to do that for you, so reader beware.
Conflict can occur when content of certain accuracy standards get judged by different accuracy standards than was understood by the author. The classic example is when someone tweets out a casual thought they had while in the shower, and then it goes viral because it contains some error. A small indiscretion–a stupid thought like what we all have–gets turned into a large one.
Audience size has a lot to do with it. The price of an error is spreading misinformation, which is proportional to the size of the audience. The price of fact-checking is spending time to do your homework, which is unrelated to the size of the audience. So for a larger audience, the cost-benefit analysis leans more and more towards fact-checking. For a small audience, at some point it’s like, why bother? You can issue a correction later if you have to.
