Or, to put it another way, would you want to read a story
by someone who doesn’t know what they're talking about?
Me neither.
In fact, even if someone sounds like they don’t know what they’re talking about, that’s
enough to turn off most people. They don’t want to read that guy’s story, or
listen to his views, or spend any time in his presence.
When it comes to communicating with people, especially people you don't know personally, to ‘sound
like’ you know what you’re talking about is more important than actually
knowing what you’re talking about.
