Probably not. They'll just write another article with an opinion that reflects the new information. Apology is unlikely. I write for a poker news site and while I don't really consider myself a "journalist," as I rarely get my information first-hand, I do try to make sure I always have the facts straight. If I'm not sure of all the details, I make sure I write as much and/or present multiple possibilities. Most of the time, I don't editorialize, as I'm just writing news, but when I do write an opinion piece, I try to be fair. It's funny, I ran into a situation recently where I basically wrote an article where the main point of it was totally incorrect. The World Series of Poker was getting ready to announce the schedule for this year and they tweeted some teasers, one of which was that there would be no "November Nine" this year (for those who don't follow poker, a few years ago, the final table of the big $10,000 Main Event that most of you have probably seen on ESPN was moved to November from July for various reasons - changing it back to July would be a very big deal). As soon as I saw that tweet, I posted an article ASAP because hey, that's huge stuff. The next day, when the schedule was announced, it turns out that the "November Nine" was simply moved to October because of the Presidential Election. I was soooooo pissed. Rather than removing the article or writing a new one (though I wrote a separate one with schedule details), I changed the headline to reflect the fake-out by the WSOP tweet, added an italicized note at the top of the article, and did a bunch of strikethroughs to show any changes. I did all that partly out of stubbornness and partly for humor purposes so people could see how the WSOP totally screwed me up.
