Ants don’t talk to each other. They don’t have meetings. They don’t send memos. What they do is leave chemical traces in the environment as they go about their work. Pheromones. The next ant comes along, reads the trace, and acts on it, then leaves its own trace, then the next ant. The whole colony coordinates not through communication but through accumulated signal in the shared environment.
There’s a word for this. Stigmergy. It’s how social insects build elaborate structures and run massive logistics without anyone being in charge of the whole. Once you know about it, you start noticing humans do exactly the same thing.
What the trail looks like for us.
Walk into a coworker’s office. Without anyone telling you anything, you can read the trail. How the desk is organized. What’s pinned to the wall. The state of the inbox. The kind of notes left in the margins of the printed agenda. Whether the calendar is color-coded or chaos. Whether they say hello to the assistant by name. Whether the dishes from yesterday are still on the desk. You haven’t had a conversation, and you’ve already learned more about how to work with this person than most conversations would have given you. You’re reading the pheromone trail.
Same in a house. The state of the kitchen after someone leaves it tells you who they are in ways nothing they say can. The way the coats land by the door. Whether the kids’ shoes are paired up or not. Whether the bills are sorted or piled. The trail is doing the talking. Same on a team. The state of the codebase tells you what the team values. The shape of the commit history tells you how they actually work versus how they describe how they work. The way the docs are or are not written tells you who’s been carrying the weight. The trail is the truth. The Slack chatter is the cover story.
Why this matters.
Once I really took stigmergy seriously, two things changed about how I work.
First, I stopped trying to coordinate everything by conversation. Most teams I had ever worked with treated conversation as the primary coordination tool. Meetings, Slack threads, status updates, syncs. The implicit theory was that if we just talked enough, we’d stay aligned. It doesn’t work past about ten people, and even before that it produces a lot of overhead. What works much better is to leave high-quality traces. Decisions written down. Code that explains itself. Dashboards that tell you what state the world is in without anyone explaining. Documentation that’s actually up to date because updating it is part of doing the work. The environment carries the coordination, and conversation is reserved for the things the trail can’t carry. The hundred-person company that coordinates through trails moves faster than the ten-person company that coordinates through meetings, because trail-reading scales and conversation doesn’t.
Second, I started reading people through their trails much more than through their words. What someone says about themselves is one signal. It’s not a bad signal but it’s not the strongest one. The strongest signal is what the environment around them looks like after they’ve been there. The person who says they care about quality and whose work product is sloppy. The person who says they value family and whose calendar tells a different story. The person who says they’re a good leader and whose team’s morale dashboard tells a different story. The person who says they’re organized whose inbox tells a different story. I’m not saying ignore what people say. I’m saying weight it less than what their trail says, because the trail is what they have actually been doing while nobody was watching, and the words are what they describe themselves doing.
A small thing about your own trail.
You leave a trail everywhere too. Most of us don’t think about it. We think about what we said in the meeting. We don’t think about how we left the room. But the people who work with you, live with you, follow you on the internet, hire you, refer you, recommend you, fire you, marry you, divorce you, are reading your trail more than they’re reading your words. Whether you knew it or not, you’ve been broadcasting all day.
This is not a guilt trip. It’s a practical observation. Once you take it seriously, a small thing happens. You start to care a little more about the trail you’re actually leaving. Not in the curated-Instagram way. In the much more boring way of “did I close the loop on that email” and “did I do what I said I’d do” and “is the state of this thing I’m leaving behind okay for the person who comes next.”
The trail compounds. The people who quietly leave good trails for a long time get a kind of trust nobody can explain, because the explanation isn’t in any conversation. It’s in the layer underneath the conversation. The people who leave bad trails for a long time develop a kind of reputation nobody can quite point to either, because that’s not in the conversation. It’s in the air. It’s in the place they were yesterday.
The pheromones are doing the work whether you notice them or not. Might as well notice.
