Obfuscation Studies

Obfuscation: deliberately increasing the complexity of a piece of writing without changing the content

Have you ever changed the words in an academic essay to make the essay sound more valid or intelligent by using complicated language? 75%

When you write an essay, do you turn to the thesaurus to choose words that are more complex to give the impression that the content is more valid or intelligent? 66%

Step 1:Take a normal string of text

Step 2: Replace every noun, verb, and adjective with the longest thesaurus entry.

•No replacement if original word is longest

•If multiple words are of equal length choose highest alphabetically

•Change ‘a’ ‘an’ etc. to keep grammar
