Of course, today, we realise that this treatment is useless. But at the time, it was the best solution available based on the best knowledge at the time: Doctors knew that the blood transferred disease around the body, so if we remove the blood, we remove the disease.

Jung, Freud and all the fathers of psychology did pioneering work on understanding how the brain works. They weren’t wrong…as the 18th century doctors weren’t wrong about blood taking disease around the body. However, we are now realising that these views are incredibly simplistic. We have built our organisations, performance management systems and training around these accepted models. But now, through neuroscience, we are learning how the brain REALLY works. We are at the start of a new frontier….
