Muphry’s Law is the editorial application of the better-known Murphy’s Law. Muphry’s Law dictates that:
- if you write anything criticising editing or proofreading, there will be a fault in what you have written;
- if an author thanks you in a book for your editing or proofreading, there will be mistakes in the book;
- the stronger the sentiment in (a) and (b), the greater the fault; and
- any book devoted to editing or style will be internally inconsistent.
