All the Feels: The Evolved Function of Every Human Emotion and Sensation
Re:Writers, 2026
Seventy-four feelings, from hunger to heartbreak, each one asked the same question: what is it for?
I am an evolutionary psychologist and the author of three books about why people are the way they are.
I write The Living Fossils on Substack, and I help run a paint-your-own-pottery studio in South Philadelphia.
New: All the Feels: The Evolved Function of Every Human Emotion and Sensation, out September 30, 2026.
I study the evolved design of the human mind: why we have the feelings we have, why we are so sure of our own good sense, and why our opinions line up so neatly with our interests.
I trained with Leda Cosmides and John Tooby at the University of California, Santa Barbara, and I was a professor of psychology at the University of Pennsylvania for more than a decade. These days I write, I talk with podcasters, and I am the junior partner in my sister's studio, The Pottery Spottery.

Why political views track people's interests far more closely than they track their stated principles, and why almost no one notices.

The mind is a collection of parts that do not always agree with one another. That explains a lot.
The Living Fossils is my Substack on evolutionary psychology and behavioral economics: the parts of our minds built for a world that no longer exists, and what they do now.
