I'd say the notion that providing lots of citations leads to people taking me more serious needs at least a citation. I don't think it works that way in general. It is also not as easy: how does pointing to another random person on the internet (my citation) make me a more credible random person? Even studies by actual scientists can be bogus. How am I to know which sources you trust? Also, I made a claim that was very easy to verify ("there are lots of studies on topic x"). Should I also provide sources if I claim "the sky is blue"?
