The Roadrunner's Guide to English: Mechanics (Type 2 Errors)
Type 2 Errors
While the Type 2 errors don't have the "do or die" importance of the Type 1 errors, learning about them and avoiding them in your writing will make you sound more educated and will give what you have to say more weight. That means you'll be more convincing, and your readers will be more impressed with you and with your message. Who doesn't want that?
