Today I sit down with Willoughby Britton and Jared Lindahl, the interdisciplinary team from Brown University that is responsible for the “Varieties of Contemplative Experience” study on the challenges and adverse effects of meditation. We talk about the design, findings, and outcomes of the study, and how it opened up a new field of interdisciplinary investigation. Along the way we ask: if someone suffers harm from practicing meditation, whose fault is it? What is the ultimate cause? And who gets to interpret the experience?
