Your town hall moved information. Belief moves on synchrony.

The transformation announcement went out on schedule. Town hall delivered, cascade pack distributed, FAQ page live. On paper, every person in the organisation has now 'heard the change'. Sometimes that is enough. More often, the pulse survey six weeks later confirms what the change lead already suspected: the information arrived, and belief didn't.

There is a physical reason for that gap. When two people are in real conversation, their brains measurably couple. In a Princeton study (Stephens, Silbert and Hasson, 2010, in PNAS), listeners' brains synchronised with a speaker telling a story… and in the best listeners, parts of the brain ran slightly ahead, anticipating where the story was going. Dikker and colleagues found the classroom version in 2017: the degree of brain-to-brain synchrony across a room tracked how engaged students were with the lesson and with one another. Dr Fiona Kerr, whose research features in the article, describes human connection as a physical event. Engagement, in the literal sense, has physics.

Hold that against how most change programmes communicate. Broadcast is efficient at moving information, and close to useless at creating the synchrony that belief travels on. A town hall can tell a few hundred people at once what is changing. The experience of being heard, challenged and answered, where the coupling actually happens, lives in conversation. And conversation is usually the first thing cut when the programme schedule tightens.

The research also rehabilitates a skill many leaders have learned to apologise for. If you have ever walked out of a meeting and said 'the vibe was off', you were reporting data your dashboard cannot collect: your own nervous system registering how much synchrony was in the room. I have had to retrain that instrument for remote work… scanning the video grid, noticing who laughs on mute (a skill in itself), and taking the conversations that matter outside the formal meetings.

(Unashamed side note: this is exactly the territory Pragma works in. When a change is technically on track but the belief clearly isn't travelling, bring it your real situation and work it through in my tone. The FAQ covers how leaders are using it.)

The full article tells the story that earned the headline: the high profile role I walked away from because of the foyer, whether that makes me a hypocrite given how hard I push reference class forecasting, and an epilogue at a pub that settled it. Read I turned down a high profile role because of 'vibes' in the foyer; the research backs me up on markwinter.com.au.
