“The sensation of being alive in the early 21st century consisted of the sense that our ability to pay attention — to focus — was cracking and breaking,” writes Johann Hari in his new book, “Stolen Focus.” Later he says, “It felt like our civilization had been covered with itching powder and we spent our time twitching and twerking our minds, unable to simply give attention to things that matter.” Same. Attention is the most precious resource we have — it’s the window through which we experience our lives. And for many of us, that window is fogging. The knee-jerk response is to blame ourselves. If our attention is waning, it’s because we’re too distractible. But if there’s a single thesis of “Stolen Focus,” it’s that we have a lot less control over our attention than we like to believe — and not just because the apps on our smartphones are cunningly designed. The book explores 12 factors that Hari believes are harming our ability to pay attention. And in it, there’s a clear distinction between what I’ve come to think of as the “demand side” and the “supply side” of attention. The demand side is the story we’re more familiar with: Entire economies and technologies are built around capturing, manipulating and directing our attention. But the supply side is just as important: A whole host of social conditions, from the food we eat to the amount we sleep to the chemicals in our air and the money in our bank accounts, determine the reservoirs of attention we have to draw on in the first place. For Hari, that means that the state of our attention isn’t merely the product of individual failing or corporate manipulation — it’s an outgrowth of some of the most fundamental aspects of our society, our culture and our economy. And as a result it can’t be fixed by a few tweaks at the margins. To do that requires a sustained, rather radical, political project. As you’ll hear in the conversation, I don’t agree wholly with Hari’s argument. But I think it’s a much needed push to look at the most fundamental of human facilities through a new lens. Life is the sum total of what we pay attention to. What forces are in control of our attention — and how we get it back — is a defining question of our age.

“Trauma is much more than a story about something that happened long ago,” writes Dr. Bessel van der Kolk. “The emotions and physical sensations that were imprinted during the trauma are experienced not as memories but as disruptive physical reactions in the present.” Van der Kolk, a psychiatrist by training, has been a pioneer in trauma research for decades now and leads the Trauma Research Foundation. His 2014 book “The Body Keeps the Score,” quickly became a touchstone on the topic. And although the book was first released seven years ago, it now sits at No. 1 on the New York Times best-seller list, a testament to the state of our national psyche. The core argument of the book is that traumatic experiences — everything from sexual assault and incest to emotional and physical abuse — become embedded in the older, more primal parts of our brain that don’t have access to conscious awareness. And that means two things simultaneously. First, that trauma lodges in the body. We carry a physical imprint of our psychic wounds. The body keeps the score. But — and I found this more revelatory — the mind hides the score. It obscures the memories, or convinces us our victimization was our fault, or covers the event in shame so we don’t discuss it. There’s a lot in this conversation. We discuss the lived experience of trauma, the relationship between the mind and the body, the differences between our “experiencing” and “autobiographical” selves, why van der Kolk believes human language is both a “miracle” and a “tyranny,” unconventional treatments for trauma from E.M.D.R. and yoga to psychedelics and theater, how societies can manage collective trauma like 9/11 and Covid-19, the shortcomings of America’s “post-alcoholic” approach to dealing with psychic suffering, how to navigate the often complex relationships with the traumatized people we know and love, and much more.
