The Cybercrime Wave That Wasn’t

The Cybercrime Wave That Wasn’t | Anomalies | Scoop.it

Ill-gotten gains are artificially bounded by zero, as there is no data on losses experienced by cybercriminals. Thus the shape and skew (mean and stdev too!) of frequency distributions are incorrect. Also: "Cybercrime surveys... exhibit a pattern of enormous, unverified outliers dominating the data... 90% of the estimate [was] from the answers of 1 or 2 individuals."  The significant harm experienced by users rather than the small gain achieved by hackers is the true measure of the cost of cybercrime.

Gary King, PhD has a nice collection of outlier event-themed research work, covering a wide range of fields of study. I think the website uses Harvard's OpenScholar CMS, which is an additional feature worth noting.

* The image that accompanies this was my choice (Prof. King has nothing to do with any errors in judgement I might make). It is a photograph of a recent annular eclipse, as observed in Southern California (Spring 2012) via Flickr.
