Oh, I don't disagree. It's just that in this specific instance it was confusing. My comment was just because I'm sure other people might be confused as well. There's a Jared Diamond like half a mile from my house, so it just popped into my head first.
I have to admit that when I first saw the title my first thought was also about the jewelry business. I guess I can blame it on brain washing from TV commercials.
It is certainly not weird at all to include the author's name if the author is a famous writer.
