Welcome back friends! Today we've got a first for you: our very first audio essay by... not me. I would call it a guest essay, but it's by our longtime Assistant Producer, Urte Laukaityte. If you're a regular listener of the show, you've been indirectly hearing her work across dozens and dozens of episodes, but this is the first time you will be actually hearing her voice.

Urte is a philosopher. She works primarily in the philosophy of psychiatry, but also in the philosophy of mind, the philosophy of biology, the history of medicine, and neighboring fields. She's particularly interested in a colorful constellation of psychiatric phenomena—phenomena like hypnosis, mass hysteria, psychogenic conditions, and (the topic of today's essay) the placebo effect.

There's almost certainly more to placebo than you realize—it's a surprisingly many-layered phenomenon. Here, Urte pulls apart those layers. She talks about what placebo can and cannot do, the mechanisms by which it operates, the ethical dimensions of its use, its evil twin nocebo, how it is woven through the history of medicine, and a lot more. She argues that, though we've learned a lot about the placebo in recent decades, we have not yet harnessed its full potential.

As always, we eagerly welcome your comments about the show. Feel free to find us on social media, or send us a note at [email protected]. We would love to hear your suggestions for future episodes, your constructive criticisms, really your feedback of whatever kind.

Alright friends, now on to our audio essay—'Rehabilitating placebo'—written and read by Urte Laukaityte. Enjoy!

A text version of this episode will be available soon.
