Headstrong

Tuning a stone-age brain for the 21st-century world

Something has shifted — and most of us can feel it, even if we can’t name it. Not broken — just operating in a world that wasn’t part of the original design.

The people I see in my office are not weak, not lazy, not failing at life. Many of them are accomplished by every metric the culture rewards. They sleep poorly. They concentrate in fragments. They feel disconnected from people they love and from work they used to find meaningful. They are anxious in ways that don’t track to anything specific, and tired in ways that don’t resolve with rest. When they ask me what is wrong with them, the honest answer is usually: probably nothing. What’s wrong is the fit.

For forty-five years I have watched human nervous systems try to do their job inside environments those nervous systems were never designed to handle. The brain you are reading this with was shaped over hundreds of thousands of years for a world of small groups, physical work, dark nights, predictable food, and conversations that happened face-to-face. It is now asked to function inside a world of glowing screens, fragmented attention, manufactured food, chronic low-grade alarm, and relationships mediated through software optimized to capture rather than connect. The mismatch is not subtle. It is the dominant fact of modern mental life, and most of the suffering I see in my practice traces back to it in some form.

This is the premise of Headstrong.

I am not here to tell you the mental healthcare system is broken — although in important places it is. The mental health field, for all its hard-won knowledge, has spent too much of the past three decades narrowing its lens to symptoms it can name and medications it can prescribe, while the upstream conditions that produce most of those symptoms have gone largely unaddressed. That is a real problem and I will not pretend otherwise. But system critique is not the work. The work is what you do with the brain you actually have, in the life you actually live. That is where Headstrong wants to live.

A Word About Me

I am a clinical psychologist. I run a private practice, lead a clinical and training organization, and chair the board of a foundation focused on advancing neurotherapy as a serious field. I have spent more than four decades watching what helps and what does not, in patients and in myself, and I am writing now because the gap between what the science actually tells us and what most people are doing about it has become too large to leave alone.

There are excellent voices in this space already, and I am not trying to compete with them. I am trying to do something most of them are not built to do: synthesize across domains, translate across audiences, and ground every claim in clinical reality rather than laboratory abstraction. If that is useful, stay. If it is not, no harm done.

What You Can Expect

Honesty about what we know and what we do not. I will tell you when the evidence is strong, when it is suggestive, and when I am extrapolating from clinical experience because the studies have not caught up. Skepticism toward simple answers, including my own. A willingness to say that a popular intervention is overhyped, or that an unfashionable one deserves another look. And a baseline assumption that you are an intelligent adult who can handle complexity, ambiguity, and the occasional uncomfortable conclusion.

What you will not get. Hacks. Hustle. Supplement stacks. Morning routines optimized for someone else’s life. The promise that any of this is easy. It is not easy. The mismatch between your nervous system and the world it has to operate in is structural, and meeting it well takes more than a checklist. It takes a framework, a few durable habits, and a willingness to do the unsexy work of paying attention to what your own biology is telling you.

Why Now, For Me

My clinical and organizational work continues, but I have chosen this moment to reflect on what forty-five years of practice has actually taught me — and to say it plainly. The timing is partly biographical. It is also that the questions I have spent a career working on are no longer specialist questions. They are questions every thoughtful adult is now being forced to ask, whether they have the language for them or not. I have some of the language. I would like to share it.

The plan is straightforward. A long-form essay roughly every other week, here. Shorter notes and prompts in between to keep the conversation going, and an open door in the comments and chat. The pace is deliberate. Thinking takes time, and so does reading something worth thinking about.

A preview, then we are done for today.

When you look at the research on what predicts healthy human adjustment — across cultures, across decades, across methodologies — four factors are cited again and again. They are older and more demanding than what wellness culture sells, and they are not arbitrary: the architecture of a stone-age brain explains why these four, and not others, are the ones that matter. The next post lays them out, and that framework is what everything else here will hang from.

Welcome. I am glad you are here.
