Will the shock of Covid change anything?

Earlier this month, a curious report caught my attention. Apparently there exists no rigorously established evidence that electric shock therapy, or ECT (electroconvulsive therapy), works. At all. In Electroconvulsive Therapy for Depression: A Review of the Quality of ECT versus Sham ECT Trials and Meta-Analyses, Dr John Read, Professor Irving Kirsch and Dr Laura McGrath have shown that the therapy, commonly administered for severe depression, has not (despite claims) been shown to have any significant positive effect, ever. It can be dangerous, carrying a small risk of death and a higher risk of serious memory loss, yet (the authors say) more than a million people worldwide are undergoing this therapy today, for no proven benefit.

I doubt I ever thought otherwise, and nor perhaps did you. I’d have labelled ECT as quack medicine, but had no idea how prevalent — even popular — it is, nor how widely it is believed in.
