The Flesch-Kincaid test is designed to assess the readability level of written text, with a formula that translates the score to a U.S. grade level. Longer sentences and sentences utilizing words with more syllables produce higher scores. Shorter sentences and sentences incorporating more monosyllabic words yield lower scores.
So, longer sentences incorporating longer words are more readable? I don’t want to think about this anymore, although I’m tempted to make some sort of image macro relevant to this featuring George Orwell.
