# What constitutes a correction?

"<a href="http://slate.com/id/2122093/">Sex and Significance</a>" originally said: "That means 10 heads in a row is significant evidence that the coin is biased; eight heads isn't." This is not right, so I emailed the author and <cite>Slate</cite> corrections department; the author subsequently wrote back saying that it should be changed, and a few hours later the sentence was changed to read: "That means 10 heads in a row is significant evidence that the coin is biased; eight out of ten isn't."

The mistake and subsequent change wasn't noted on <cite>Slate's</cite> seemingly comprehensive <a href="http://slate.com/id/2122277/">Corrections</a> column. (Seemingly comprehensive because it includes such corrections as "blogger Colin Henderson was referred to as "Harrison" on a second reference due to an editing error." Isn't this unnecessarily self-flaggellating? Can't you just fix this?) So, what corrections get reported, and what don't?
