Even good doctors can get sued. But it speaks to more about why people sue; (doctors did a bad human-interaction job rather than they did a negligent job)

I do wonder about the nature of doctoring. Do you happen to get 3% (arbitrary number) wrong; and if you are also bad at people-skills, this bites you. whereas if you get 3% wrong and you are good at people skills you avoid being sued 99% of those 3% of cases.
