The most accurate starting point I have is a Tuesday in Q3. A rep closed the biggest deal in company history. The celebration was real. The room felt empty.

Not tired. Not distracted. Empty. Something had stopped landing the way it used to, and I didn't have language for it.

I did what most leaders do. Attributed it to stress. Ran harder. Tightened the plan, added a meeting, got more precise about the things that were already precise. The numbers kept moving. The emptiness didn't.

Eventually I stopped trying to outrun it and started looking for language. Not in leadership content. In consciousness research. Neuroscience. The science of what actually happens between people when something real is passing between them versus when it isn't. That territory is less crowded and more honest.

What the research shows is not complicated, just underused. Teams synchronize physiologically during real communication. Brain activity aligns when something important is actually landing. Heart rate variability tracks leadership effectiveness better than most 360 tools. The nervous system has been measuring the room the whole time. I was measuring something else.

The research keeps pointing at the same phenomenon from different directions. Neural coupling. Physiological synchrony. Collective coherence. The name isn't settled but the thing is real. Something measurable exists between people in a room, and it determines nearly everything about what happens there. I call it the field.

The Tuesday in Q3 wasn't an anomaly. It was a reading. The room was telling me the work had drifted from something true toward something performed. I had been the last one to notice.

The gap between those two states, present and performing presence, is not soft. It's measurable. People feel it before they can name it. Rooms respond to it. The variable isn't strategy or structure. It's what the person at the front of the room is actually carrying in.

Co-authoring a book with Dr. Carlos Warter (Park Street Press, spring 2027) on the nature of the field itself — what it is, how to sense it, and what it means for how humans organize, decide, and evolve. Field Notes is the public record of getting there.

Still working out what that Tuesday was pointing at. Fifteen years in and this is still where the interesting questions are.
