In this episode of Dharma Lab, Cortland Dahl and Richard Davidson are joined by Center for Healthy Minds researchers Simon Goldberg, Polina Beloborodova, and Matt Hirshberg to examine the “shadow side” of meditation. When people report anxiety or other difficult experiences during practice, how can we tell whether meditation caused them? The group discusses what studies of meditation apps and mindfulness programs reveal, why intensive retreats are a different question, and how loneliness, support, and our expectations of practice shape what happens when we sit down to meditate.

Does meditation put us at risk for difficult mental, emotional, perhaps even physical experiences? Polina: We found in this paper that about 30% of the participants across both of our studies did have some sort of negative experiences during their meditation training. Again, these may not have been caused by meditation training, but have been subjectively attributed by participants to the meditation training. Matt: What’s the view that people bring to meditation? What’s the conceptual understanding of what meditation is supposed to do? Because if your motivation is to not feel sad, and you believe meditation should be the absence of sadness, and you experience sadness in meditation, then your subjective experience of that is going to be very different than someone who feels like, “Well, my motivation is to train the mind and develop equanimity. And I expect that anything that can arise will arise in meditation.” And so when sadness arises, then, like you said, Cort, like people have just reflected, that actually might be an invitation to develop that equanimity. 01:32 Meet the Researchers Cort: Welcome, everyone, to another episode of Dharma Lab. I am Cortland Dahl, your co-host, along with world-renowned neuroscientist Dr. Richard Davidson, who many of you probably know. We are here to have a really important and what I think will be a very interesting discussion about the shadow side of meditation. There have been a lot of headlines coming out of a lot of the research that’s happened over the years about a supposed dark side to meditation. Does meditation put us at risk for difficult mental, emotional, perhaps even physical experiences? This has been a major topic of research, including the research that we’ve done at the Center for Healthy Minds. So we’re going to unpack that a little bit. What does the science really say? There are actually some very surprising and even counterintuitive findings here, and we have an all-star panel to have this discussion. Here joining Richie and me are Polina Beloborodova, who is a social psychologist and a postdoctoral research associate at the Center for Healthy Minds. We’ve also got Simon Goldberg. He’s an associate professor in counseling psychology at UW–Madison, also one of our colleagues at the Center for Healthy Minds. And finally, Matt Hirshberg, another colleague from the Center for Healthy Minds and a research assistant professor at the Center. All three of our colleagues, in addition, of course, to Richie, are some of the leading researchers on this topic. So, Richie, why don’t I turn it over to you? Maybe you could provide a little bit of context. Why is this even on the map of scientific research? And then we can dive into the specific paper that was published recently and some of what we’ve learned. 03:17 Why Study Meditation’s Side Effects? Richie: Meditation and related practices today are being used in a wide range of contexts, one of which is with individuals with elevated rates of depression and anxiety and other kinds of psychiatric issues. Whenever we are dealing with interventions, particularly when they’re applied to patient populations, in addition to looking at the beneficial outcomes, we always want to monitor for side effects, if you will. This is something that is true of really all areas of clinical science, whether it’s a medication trial for a physical disease or a behavioral intervention for a psychiatric problem. We really need to, as researchers, be attentive to the possibility that, of course, although our motivation in utilizing these interventions is to benefit people, there are times when the interventions that we’re working with can actually either not have much effect or potentially even produce harm. It’s our obligation and responsibility to carefully and honestly characterize these potential side effects and publish them so that we can be alert to these possible dangers. Of course, one of the most important issues is: Can we predict who might be likely to have a possible negative effect and, in that way, ameliorate the possibility up front, if you will, so that we can tailor the interventions more specifically to those who are most likely to actually have benefit? So that’s the broad framing. In the area of meditation, there have been a number of scientists at very respectable institutions who have published some observations about possible negative side effects. It underscores the importance of taking this seriously, and this is something that we at the Center for Healthy Minds have been doing for quite some time. We really have the all-star team here. I’d like to first turn it over to Polina, who has published a very recent paper. She’s the first author of this paper on potential adverse experiences associated with digital forms of meditation training, something that has not been extensively examined in the past. So, Polina, please tell us what you found and give us some insights about … This is a public episode.
