We sit down with Danielle Fuller, creator of Scientific Enneagram, to preview her brand-new podcast coming to our channel in January 2026.

Danielle is an engineer and a systems thinker who sees a huge gap between the world of Enneagram teaching and the world of science and research. Her passion is to become a bridge-builder between those two spaces, helping us ask better questions, see the limits of what we know, and slowly build a real body of work around Enneagram and science.

In this conversation we talk about:

• Why doing good science with the Enneagram is so hard (self-reporting, motives vs. behavior, and the limits of current tools)
• How psychology has moved through introspection, behaviorism, psychoanalysis, and the cognitive revolution—and where the Enneagram might fit in that story
• The tension between qualitative narrative work (like panels and coaching) and quantitative data (stats, brain scans, validated scales)
• The ways cultural bias shows up in psychological research (WEIRD samples, Western assumptions, college-student data) and what that means for a tool that claims to describe 8 billion people
• Why motive may be one of the most important things science could study—and how the Enneagram offers a lens, not the final word

We also get into funding, grad students, file-drawer problems, conspiracy thinking, and why Danielle is doing this as a passion project even though there’s basically no money in it.

If you’re a scientist, grad student, therapist, or researcher who’s Enneagram-informed (or even Enneagram-skeptical) and want to talk, Danielle would love to hear from you: [email protected]

I’m genuinely thrilled about this show. My hope is that The Scientific Enneagram becomes a hub for serious conversations about motive, method, and what we can actually know when we bring the Enneagram into the lab.
