In response to widespread complaints, the National Jurist has reviewed its use of data from Ratemyprofessors.com. While NJ still insists it was appropriate to use this haphazardly collected data for one-fifth of each school’s rating, it has been forced to revise the RMP score for two-thirds of ranked schools. Let’s say that again: The National Jurist went to press with a ranking system that included mistakes for two-thirds of the ranked schools. Even if one were to believe that it was reasonable to use RMP scores in the first place — and it was not (as discussed here and here) — this degree of sloppiness is appalling. It was utterly irresponsible for NJ to go to press with rankings based on such slipshod work, and a disservice to the prospective students NJ was purporting to serve. Brian Leiter is correct — NJ should simply confess error, deep six these rankings, and start over from scratch.
