In a Nov. 12 "Politics," Timothy Noah referred to the Medicare tax, which taxes all earned income at 1.9 percent, as regressive. A flat tax like this one is merely not progressive. To be regressive, a tax must be higher for people at lower incomes.

In the Nov. 10 "Explainer," Christopher Beam originally gave the wrong year for the D.C. sniper attacks. They took place in 2002.

In the Nov. 10 "Moneybox," Daniel Gross misidentified the name and current affiliation of one of the authors of a paper he cited. Margaret McConnell is a research fellow at Harvard's Center for Population and Development Studies. He identified her as Mary McConnell, a graduate student.

In a Nov. 10 "Prescriptions," Timothy Noah misspelled the name of the U.S. representative for Illinois' ninth district. It's Jan Schakowsky, not Schakowki.

In the Nov. 9 "Ad Report Card," the first name of Courteney Cox was originally misspelled due to an editing error.

In the Nov. 9 "Explainer," Brian Palmer mistakenly referred to reloading a handgun by inserting an empty, rather than a full, magazine into the grip.

In a Nov. 6 "Book Club" entry, the name of the National Center for Complementary and Alternative Medicine was misspelled in a way that suggested the therapies in question would be flattering to patients or offered free of charge.

In an "Explainer" published Oct. 26, 2001, and reprinted Dec. 4, 2008, Chris Suellentrop misidentified scopolamine as a barbiturate rather than a tropane alkaloid.
