"If you Google this string, you'll find the arguments" is a logical fallacy. You are claiming that there are arguments for why this rule is true, but not providing any. If anything, the only thing this statement proofs is that you are not able to explain why doing this is even a good idea.
And FWIW, I actually google this and none of the first 5 results actually explained why this rule makes sense. They were all posts of the form "20 rules to blindly follow when writing a resumee".
