What this is
There is a particular kind of psychology finding that, when you encounter it, makes you sit slightly differently for the rest of the day. Not advice. Not life-hack. Not "five signs you're an empath." Something that changes, in a small way, how you read a room. HeadFacts is the channel for those.
Each video is a one-finding essay. One claim, one paper or program of research it comes from, and one honest framing of what the finding does and does not say. The aim is to be the thing you'd send to a friend who reads Sapolsky for fun — a level deeper than a TED summary, a level shallower than a literature review.
A theory of mind without a theory of when the theory fails isn't a theory of mind. It's a slogan. — from a working note
The shape of a HeadFacts essay
Every clip follows the same five-beat structure, which we've found gives the listener room to think between claims rather than being drowned in them.
- The image.
- The finding.
- The qualifier.
- The why.
- The sit.

What we don't do
HeadFacts isn't a self-help channel. It doesn't tell you how to "rewire your brain" or what your sleep schedule should be. It doesn't sell a course. It doesn't have an opinion on your morning routine. The behavioral sciences are far more interesting when you stop asking them for life advice and start asking them what's actually happening in the room.
