<P> The title of the song refers to Douglas Coupland's novel Shampoo Planet, wherein the main character, Tyler Johnson, says: "I am writing a list of tragic character flaws on my dollar bills with a felt pen . I am thinking of the people in my universe and distilling for each of these people the one flaw in their character that will be their downfall--the flaw that will be their undoing . What I write are not sins; I write tragedies ." </P> <P> "I Write Sins Not Tragedies" is Panic! at the Disco's first single to have a music video .
