Who guards the guardians?

Soon-to-be car buyers and Consumer Reports devotees, listen up: this article lays bare the various confounding factors that undercut the validity of CR's car ratings. You may be surprised at the author's appraisal of the extent of the damage--the long list of grievances includes experimentor bias, inconsistent data based on different levels of maintenance, ambiguous vocabulary, and a lot more. It's enough to make a dead statistician want to regress--but you don't need any kind of specialized know-how to understand that there are some "serious" issues going on over at CR.
