Frequency Over Force

In 1975, millions of moviegoers watched Jack Nicholson convulse under electroconvulsive therapy (ECT) in One Flew Over the Cuckoo’s Nest. Strapped to a gurney, jaw clenched, body writhing, he became the enduring cultural image of psychiatry’s reliance on electricity: blunt, violent, and terrifying. For decades afterward, ECT was remembered less as a medical treatment than as a cinematic trauma.

Yet psychiatry embraced it for a reason. ECT worked. For patients with severe depression, catatonia, or psychosis, it often succeeded where every other therapy failed. It could pull people back from the edge of suicide. But it required overwhelming the brain - flooding it with current, triggering a controlled seizure that somehow restored function in ways medicine didn’t yet understand.

ECT worked, and perhaps just as importantly, it looked like it worked.’ The convulsion was legible proof that something had happened. In an era when psychiatry was desperate to be taken seriously as scientific medicine, this mattered.

To outsiders, this was the paradox at the heart of modern psychiatry. To heal the most delicate organ, doctors used an invasive intervention. Electricity was a blunt instrument, and doctors wielded it hoping that in overwhelming the brain, something might reset.
