About The Dopamine Theory

This site exists for people who’ve always felt like they were wired differently — and are starting to realise that’s not a problem to fix.

What we cover

The Dopamine Theory explores personality psychology — MBTI types, cognitive functions, the Enneagram, attachment styles, and what modern psychology says about how we think, relate, and recharge.

We go deeper than most personality sites. We’re not interested in listicles that confirm what you already want to hear. We’re interested in what’s actually true about how different minds work, what that means for relationships and careers, and how to build a life that fits your actual wiring instead of the one you were handed.

Who writes here

The Dopamine Theory is written and edited by Keith Lacy — a writer, former agency CEO, and INTJ who spent the better part of twenty years studying people in high-stakes professional environments before turning that lens inward.

Keith’s work has always lived at the intersection of psychology and performance — understanding why certain people thrive in certain environments, why smart people make bad decisions under pressure, and what personality frameworks actually get right about human behaviour. He writes from experience, not just research.

Our editorial approach

Every article on this site is written by a human and reviewed for accuracy before publishing. We cite primary research where it exists, and we’re honest when the science is mixed or incomplete. We don’t publish clickbait, we don’t pad word counts, and we don’t write things we don’t believe are true.
