“Secret statistical methods for picking and assessing employees seem to promise a competitive edge,” Professor Pasquale writes. “Whether these methods deliver or not is unclear, and they feel ‘creepy’ to many workers, who fear having a critical aspect of their lives left to mysterious and unaccountable computer programs.”

This article is a bit narrow minded, IMHO. It speaks too much of the company and hiring and firing employees. There are an estimated 53 million freelancers in the US alone. (See https://www.freelancersunion.org/blog/dispatches/2014/09/04/53million/). This trend is only continuing as the friction of obtaining talent on a per project basis continues to fall. The job of the future is the anti-job. Now, this doesn’t mean the thesis of the article is incorrect. More and more metrics and the reputation market will continue to play an important, nay critical role. In fact, that’s part of what’s leading the revolution to freelancers.
