The History of Bad Ideas: Overdiagnosis
12 August 2026
We come to the end of this series of bad ideas with a conversation with neurologist Suzanne O’Sullivan about the problems of living in an age of diagnosis, when all medical conditions need a label and new labels appear all the time. What happens when the classification criteria for conditions like autism and ADHD get broader and broader? Are doctors or patients driving this? When does predictive testing do more harm than good? Why does advocacy for sufferers get in the way of good health? Is de-diagnosis achievable?
