The power of vocabulary: Candidates that dumb it down do better

Americans may not want a simpleton for president, but they like candidates who speak like one. 

That's according to a new analysis by the Boston Globe that rated 19 of the 2016 presidential candidates and found the ones who use the most elementary language perform best in the polls, while those who employ more complex, sophisticated speech do the worst. 

Consider the best- and worst-scorers: Donald Trump announced his candidacy in fourth-grade language according to the Globe's analysis. He's outperformed all expectations and has led almost every poll almost since he declared.  

Compare him to the candidate who, at a 10th-grade level, is spinning the most sophisticated sentences of the pack: former governor of Virginia and a Republican candidate Jim Gilmore. Never heard of him? Perhaps, given his relatively high-falutin' speech, it's no surprise. The former governor polls at less than one percent according to Public Policy Polling, so low he didn't even make the cut for the two GOP undercard debates. 

Whether it's linguistic austerity à la Ernest Hemingway or just plain inarticulateness, Americans appear to be looking for a candidate who's more Dr. Seuss than Shakespeare. In fact, political rhetoric has steadily become simpler, practically since the nation's founding, and experts say it's not necessarily a bad thing. 

For its analysis, the Boston Globe scored the announcement speeches of 19 presidential candidates, Democratic and Republican, using the Flesch-Kincaid Readability Test, which takes into account the average number of words per sentence, the average number of syllables per word, and other factors, to determine at what grade level a candidate is speaking. 

The outspoken (and plainspoken) Mr. Trump, who relies heavily on words such as “very” and “great,” and attacks his foes by calling them “losers,” “haters,” “dumb,” “idiots,” “morons,” “stupid,” “dummy” and “ disgusting,” clocked in at a 4.1 grade level, the lowest of the bunch.  

"He speaks in punchy bursts that lack nuance," reports the Globe. "It’s all easily grasped, whether it’s his campaign theme (“Make America Great Again”), words about his wealth (“I’m really rich”), or his disparagement of the Washington culture (“Politicians are all talk, no action”)."

What does it tell us about the state of our democracy that a man who speaks in sound bites is soaring in the polls?

Quite simply, that in an age of snappy sound bites and 140-character Twitter tweets, candidates must communicate in pithy bursts to get voters' attention.

And even more important than getting voters' attention, simple language also helps candidates connect with voters. 

"A leader's job isn't to educate the public," Jon Favreau, a former Obama speechwriter, told the Globe. "It's to inspire and persuade them."

It's possible that simpler language also quells voters' anxiety. When the issues in the world appear more complex and threatening than ever, perhaps Americans want to feel that there's a confident leader with a simple, or at least simply-worded, solution. 

And in the case of plainspoken candidates like Trump and Ben Carson, a neurosurgeon who separated conjoined twins but speaks to his supporters at a sixth-grade level, talking like "regular Americans" helps reaffirm their outsider status.

"Trump’s rejection of 'convoluted nuance' and 'politically correct norms,' mark him as authentic in certain corners and advance his cred as a plainspoken guardian of the American way. By not conforming to the standard oratorical style, he distinguishes himself from the pompous politician," Politico wrote in August. 

And it turns out that Trump's simplified speech is part of a much larger historical trend. Our politicians' rhetoric has been growing more and more elementary since the nation's founding. 

George Washington's farewell address in 1796 ranked at the graduate-degree level (Grade 17.9), while Abraham Lincoln's "Gettysburg Address" in 1863 was 11th-grade complexity. John F. Kennedy's 1961 inaugural​ in which he uttered the famous words, ​"Ask not what your country can do for you,"​ ranked at 13.9. Today, most State of the Union addresses, including President Obama's, clock in at an 8th-grade-level. 

“It's tempting to read this as a dumbing down of the bully pulpit,” Jeff Shesol, a historian and former speechwriter for Bill Clinton, told the Atlantic last year. “But it’s actually a sign of democratization. In the early republic, presidents could assume that they were speaking to audiences made up mostly of men like themselves: educated, civic-minded landowners. These, of course, were the only Americans with the right to vote. But over time, the franchise expanded and presidential appeals had to reach a broader audience.” 

It's a secret Trump, whom nearly one-third of registered Republicans support, seems to know very well.
