He is particularly interested in global health and pandemic prevention, anti-poverty efforts, economic policy and theory, and conflicts about the right way to do philanthropy.

As strange/great/alarming as Americans' pop culture-based naming habits are, the numbers involved are fairly low. It's striking that 241 babies were named after the Dothraki word for "queen" in Game of Thrones last year, but that's a trivial fraction of the total number of babies born in 2013. If we really want to see what's trendy in baby-naming, we need to look at total volume as well as the speed with which a given name is gaining popularity.

So that's exactly what David Taylor of did. To find the trendiest names throughout the years, he devised a "trendiness" score, borrowing a technique from chemistry. The score for a given name is equal to the peak frequency of the name divided by the number of years between when it first hit 10 percent of that peak frequency — as it got more popular — and when it last hit the 10 percent market, on its way out. The resulting quotient is maximized by names that get very, very popular for very, very brief periods — trendy names, in other words.
