Statistics and Genealogy

My son, the Astrophysicist, recently wrote a blog post entitled, "Is Salt Lake City America's Vainest City? Correcting Forbes." This article is an excellent example of why you do not want to get into a dispute with someone from my family. On the other hand, it is also a very good example of why people and genealogists in particular, need to be aware of the pitfalls of relying on popular media articles quoting statistics of any kind whatsoever.
