The Agenda with Steve Paikin S12E147 - How Effective Are Antidepressants? & A Great American Essayist

Canada has some of the highest rates of antidepressant use in the world. These drugs are ubiquitous, and are prescribed to adults as well as children. But how much do we know about how they work, and how effective they are? The Agenda discusses the science behind antidepressants. Then, Nam Kiwanuka talks to celebrated novelist and essayist Marilynne Robinson about her latest collection of essays, "What Are We Doing Here?" On the agenda: America's political polarization, the Christian right's embrace of Donald Trump, and whether Christianity has a place on the left.
