In the Oct. 1 "Chatterbox," Timothy Noah wrote, incorrectly, that in an interview with Katie Couric of CBS News, Sarah Palin could name no Supreme Court decision apart from Roe v. Wade.

In the Sept. 30 "Explainer," Noreen Malone originally understated the independence of the Office of Special Counsel and included a reference to Patrick Fitzgerald that was unclear about the actual scope of his authority.

In the Sept. 30 "Shopping," Laura Moser mistakenly referred to the Federal Bureau of Investigations, plural. It is the Federal Bureau of Investigation.

In the Sept. 26 "Jurisprudence," Charles Homans stated that Ted Stevens' wife, Catherine, was seated in the second row of the courtroom during his trial. She was not.

In a Sept. 26 "Movies," Josh Levin misquoted a line from Eagle Eye. The correct quote is "she could probably turn a train into a walking duck."
