The lowest medical malpractice insurance rates are found in Minnesota, Wisconsin, Iowa and the Dakotas. Why is that? Probably not because doctors there have managed to achieve anything resembling error-free practice; and probably not because the five states, taken as a whole, are distinguished by any unusually pro-defendant set of tort laws. MedInnovationBlog takes up the question here and here, and speaks with a mutual insurer executive in search of explanations, which may include (among others) a "culture of collegiality among doctors and society as a whole", a hard line against doubtful claims, and a paucity of giant verdicts of the John Edwards variety.
