The results were surprisingly close (and I know my writing skills are objectively nowhere close to Twain's). The Tone Analyzer breaks writing down into three tones: emotional tone, social tone, and writing tone. Within those categories, Twain scored 4 percent emotional, 88 percent social and 7 percent writing. I went 2 percent emotional, 90 percent social and 6 percent writing. (The unaccounted percentage points seem to be proper nouns and other words the computer couldn’t understand.) It also picked other notes out of our writing, like words it deemed cheerful. Twain had 4 cheerful words (dear, pleasure, thanks and pleasant), and I had only 1 (hope).
