Nearly 10 percent of college graduates think television’s Judge Judy serves on the Supreme Court, according to a new report released this month.

The report, titled “A Crisis in Civic Education,” was based on a survey of 1,000 adults in August and concludes that “recent college graduates are alarmingly ignorant of America’s history and heritage.”

“They cannot identify the term lengths of members of Congress, the substance of the First Amendment, or the origin of the separation of powers,” the report said, referring to college graduates.

The lack of civic knowledge extended to the Supreme Court, where 9.6 percent of college graduates incorrectly identified Judith Sheindlin — who handles small legal disputes on the TV show “Judge Judy” — as a justice. Another 5.5 percent of college grads picked John Kerry, the former senator who is now Secretary of State, as a member of the court.
