The surgery did what scientists said it did; the question is why did they judge this to be a good thing for those said to be mentally ill? It was that evaluation process that provided a context for Freeman and others to do the surgery.
So, could something like this happen today? Could psychiatry -- or some other branch of medicine -- adopt a form of care that we would later come to see as harmful? The history of medicine certainly warns us that doctors can be deluded about the merits of their therapies, and today that whole decision-making process is greatly influenced by pharmaceutical companies' money, which only increases the possibility of medicine going astray. The lobotomy story really should remind us of that possibility.
