An investigative look at a heretofore little known phenomenon. The full research paper referenced is available which is a plus. However, the piece is written in a manner, which to a certain degree, presumes familiarity on the part of the reader with the broader subject matter. A minor quibble and slight failing to be sure, but it can leave the uninitiated at somewhat of a disadvantage. My recommendation, time permitting of course, would be a light reading of the study, then a close reading of the piece, and lastly a casual but full read of the study. Now, while this strategy may only work for the truly intellectually inquisitive, it is nevertheless the best way to get a fuller picture of the topic, so to speak. All in all though a worthwhile read. Four stars!
