What Fireworks and Face-to-Face Have in Common

Happy Friday. Its a great day to read your latest Human Prowess article. We live in a world where machines are getting better at nearly everything, and yet the one thing that remains irreplaceable is human excellence itself. That is human prowess, and it is what we are constantly striving toward. You are reading this because you are striving for it too. Let's get into it.

One week from today, millions of people will do something their brains were literally designed for. They will gather. They will be in rooms and yards and fields with other people, close enough to read each other's faces, close enough for something to happen neurologically that no screen has ever been able to produce. We have spent this Signal Series building a case for in-person communication. This Friday, we are giving you the science. Next Friday, you get to live it.

In our last letter we acknowledged that the standard for communication in society has dropped, and that it has dropped quietly. That drop has created a gap that intentional and deliberate people can step into. We discussed what excellent communication builds, which is trust, and what trust unlocks, which is the willingness of other people to take a risk on you, and in turn the options and freedom that come with that.

We left something on the table intentionally, as this is Letter II of IV in our summer Signal Series. We addressed that in-person communication will always beat digital interaction, but it is important to understand why, because this heavily influences how we choose to structure our time and our relationships.

There is something that occurs when two people are in the exact same room There is something that occurs when two people are in the exact same room that does not happen anywhere else. It cannot take place on a call, a Zoom, a FaceTime, or through a screen. It sits at a biological level, and it is something that your brain does in person that it physically cannot do through a device, no matter how sophisticated that device becomes. That is the defensible human mode. Once you understand what this something is, you might never look at your communication choices the same way again.

In 2012, neuroscientist Uri Hasson at Princeton University published research that would change how scientists think about conversation. Using a neuroimaging method called hyperscanning, which measures the brain activity of two people at the same time, it was found that when a speaker tells a story and a listener receives it, the brain of the listener begins to mirror the speaker's brain, activity pattern by activity pattern, in real time. This is called brain coupling, and the stronger the coupling, the greater the listener's comprehension (Hasson et al., Trends in Cognitive Science, 2012, Vol. 16, No. 2, 114 to 121).

Let that shit sink in. Two human brains, when genuine communication takes place, begin to synchronize on a neurological level.

A companion study published in the Journal of Neuroscience compared brain activity during face-to-face dialogue versus back-to-back dialogue, and the results were unambiguous. The coupling required both the live visual exchange and the turn-taking behavior of real dialogue. Remove either element and the synchronization between two brains collapses (Liu and Pelowski, Journal of Neuroscience, 2012, Vol. 32, No. 45, 16064 to 16069).

Your brain operates at a reduced capacity when the person in front of you is on a screen rather than in a room.

The last piece is oxytocin, which is a neuropeptide released in the brain during physical proximity and face-to-face interaction. It is the chemical foundation of trust, social bonding, and what researchers describe as the experience of feeling safe, known, and worth investing in. A 2026 review found that while face-to-face interaction reliably stimulates oxytocin responses linked to social bonding and stress reduction, text-based communication produces effects neurochemically comparable to having no contact at all (Wieczorek et al., ScienceDirect, 2026).

Read that again. Texting someone, in terms of what it does to the brain's bonding chemistry, is closer to silence than to presence.

No machine or digital intervention will ever deliver what that feels like. It is fundamentally human, and probably always will be.

We are not arguing against digital communication. We use it and we leverage it. This letter comes to you digitally. But there is a real difference between a tool that supplements human connection and a habit that replaces it. Those who understand what a screen cannot carry, and who make deliberate choices about when to upgrade the communication channel, are the ones whose communication will build the kind of trust that our brains were designed to generate and respond to, and that build relationships aligned with human excellence.

Next Friday, most of us will be in a room with people we love. Let yourself be present for it. Your brain has been waiting for exactly that.

This letter does not reach you by accident. Human Prowess is a private newsletter growing the way good things do, hand to hand, between people who are serious about the work. If someone came to mind while you were reading, the kind of person who would value this the way you do, send it their way. Some things are better passed hand to hand.

See you in two weeks, Jaron
