Is Congress getting dumber?

The Capitol Building in Washington, D.C.

Think members of Congress act like a bunch of high school students? You might be on to something. A recent study from the Sunlight Foundation found that members of Congress tend to speak at about a 10th-grade level.

The Sunlight Foundation analyzed
every word spoken by every member of Congress on the floor of the House
or Senate. Sunlight imported the words into a searchable database and
then "ran them through an algorithm to determine the grade level of
congressional discourse," according to a buzzy story from NPR.

The finding: Congress is speaking
at a lower academic level. Back in 2005, members of Congress spoke at a
level equal to a high school junior. Now, the numbers have dropped off.
Congress talks like a bunch of sophomores. Sunlight used something
called the "Flesch-Kinkaid" scale to determine speech level. Longer
sentences and words with more syllables equal higher grade levels.

Some interesting factoids from the Sunlight Foundation's study:

—"Prior to 2005, Republicans on
average spoke at a slightly higher grade level than Democrats. Since
then, Democrats have spoken on average at a slightly higher grade level
than Republicans."

—On average, Congress members who are moderate speak at a higher level. Those on the far right and left speak at a lower level.

—Don't assume you speak at a higher level than your representative. The
average American speaks between an eighth- and ninth-grade level.

It is tempting to see these results and say, "Congress is getting dumber," but a piece from the Atlantic suggests another theory.
Perhaps Congress is just getting better at getting its points across.
After all, why make an issue or speech or anecdote more complicated than
it has to be?
