According to an analysis by the Sunlight Foundation, members of Congress are either a) becoming more plainspoken, or b) getting dumber. I know which one I'd put my money on, but here's what the report has to say:
Congress now speaks at almost a full grade level lower than it did just seven years ago, with the most conservative members of Congress speaking on average at the lowest grade level, according to a new Sunlight Foundation analysis of the Congressional Record using Capitol Words.
Of course, what some might interpret as a dumbing down of Congress, others will see as more effective communications. And lawmakers of both parties still speak over the heads of the average American, who reads at between at 8th and 9th grade level.
Today’s Congress collectively speaks at a 10.6 grade level, down from 11.5 in 2005. By comparison, the U.S. Constitution is written at a 17.8 grade level and the Declaration of Independence at a 15.1 grade level. The Gettysburg Address comes in at an 11.2 grade level and Martin Luther King’s “I Have a Dream” speech is at a 9.4 grade level. All these analyses use the Flesch-Kincaid test, which equates higher grade levels with longer words and longer sentences.
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.
