If you don’t know something, and know you don’t know something, you’re likely not going to do something bad with that information. For example, if you don’t know anything about engines, you’re probably not going attempt to fix one.

But often times we think we know something, and are confident that what we know is true, when it really isn’t. And that’s what gets us in trouble. For example, thinking you know something about engines, but instead you flood the cylinders and require a real mechanic to fix it instead.
