“Sex and Significance” 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 Slate 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 Slate’s seemingly comprehensive Corrections 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?
