In my post titled “I can’t tell you what ‘insight’ looks like, but I’ll know it when I see it” (28 May 2009) I mentioned a study conducted by Jonah Berger and Gael Le Mens on the rise and fall of popularity in given names. The latest issue of Knowledge@Wharton describes this research, and a link to the article, “How adoption speed affects the abandonement of cultural tastes.” For your convenience, clicking on this title here will take you to the article.  A key finding from this study is that the faster a name rises in popularity, the more quickly it falls out of favor.
