To prescribe or not to prescribe! Watch a lively debate from Intelligence Squared U.K. on the benefits and hazards of the increase in prescribing medication for mental disorders. The proposition is "Psychiatrists and the Pharmaceutical Industry Are to Blame for the Epidemic of Mental Disorders", and those arguing for this proposition point out that doctors don't know how these medications and even when the drugs do work, they don't perform much better than placebos. They say pharmaceutical companies are hyping disorders that only their profitable new drugs can fix.
The couple arguing against this proposition argue that the drugs do work and that mental disorders aren't really at epidemic levels thanks in large part to these drugs. They say that by demonizing these drug treatments, people are only increasing the mental health stigma that prevents people from getting treatment in the first place. It's a wide-ranging debate that touches on a lot of issues personal to many people, and the audience voting at the end has an interesting outcome.
