A reminder: please do not EVER ask me for sources. I will not provide them and I will delete your comment requesting them. I am not interested in providing sources on demand, and I do not care in the slightest if you decide to ignore what I say because I will not provide sources to you on demand.
I've been doing this since 2003. And one thing I have observed over the years not one single person who didn't believe the facts I cited and demanded sources in order to confirm that I was relaying the information correctly has ever subsequently changed his position as a result of being provided with an accurate source that states precisely what I said it did.
Furthermore, the instinctive demand for sources is a strong, though not reliable, indicator of gamma. Yes, there is occasionally the rare individual who actually intends to examine the source in order to do his own analysis, but such individuals are usually inclined to simply resort to a search engine rather than ask someone else for a hyperlink to a readily available URL or PDF file.
I don't provide sources for the same reason I don't provide explanations anymore: providing either is merely viewed as an invitation to argue over the source or the explanation. Since I'm not interested in doing that, I'm shutting down the whole process before it starts. This is a blog, not a science journal, what I write are opinions, hypotheses, and logical conclusions, not scientific papers, and I am under no obligation to undergo any peer review process here.
