Note the URL for that headline: http://www.newyorker.com/***humor***/borowitz-report/scalia-...

Although it is saying something that the top 3 most popular stories are from the humor section.

It does feature satirical articles and columns, including the Borowitz Report, of which that Scalia article is one installment. (One of its most famous regulars was James Thurber, creator of Walter Mitty and a rare kind of humorist, still widely read decades after his death.) But it is not a satirical magazine cover-to-cover. It's particularly well-known for its short fiction and criticism.

If you look at the URL for that article, you'll see it's filed under the "humor" folder. Other articles on the site are legitimate.
