A Politico post says that President Obama’s State of the Union speech in January registered at an 8th-grade reading level. The score in question was calculated using the Flesch-Kincaid Readability Test, which looks at average word length and average sentence length to determine the reading difficulty of a given text.
Obama’s detractors may not want to read too much into the statistics, however. The formula has its limitations, namely that it assumes that a longer word (more syllables) is always more difficult to understand than a shorter word (fewer syllables). While many readers may agree with this assumption when the words are pulchritudinous and comely, they may not agree when the words are toboggan and pulk.
