Finally! Slate brings us a use for Big Data we can all endorse: "In his blog, Matt Daniels, a data scientist, compared the lyrics of 85 rap artists using a method called token analysis. A computer program counts the number of unique words that appear in a text of a given size." Using this program, one can determine which Supreme Court justices in history have the most complex vocabularies and how those justices compare to rappers.
For those of you wringing your hands, troubled you may have a less complex vocabulary, take heart.
"[N]ot all great justices are great writers. John Marshall, who scores even lower than DMX, was the greatest justice of all time."
