Trust and Trade
This Trust and Trade post follows a pattern you’ll often see. A story from recent history will introduce a behavioral foundation from our deep origins. I chose to begin with Maurice, introduced to me by Robin Pierson’s excellent podcast The History of Byzantium.
Workplace advice rarely begins with the murder of innocent children.
Perhaps it should.
In the winter of 602, Emperor Maurice of Byzantium made a decision that would cost him everything. His army was exhausted after years of campaigning north of the Danube. Supplies were thin. Winter was brutal. Tradition dictated that troops return home.
Maurice ordered them to stay. To cut costs, he halted supply shipments and delayed payments. He remained in Constantinople, far from the frozen camps.
A low-ranking officer named Phocas rallied the starving troops. Mutiny turned to revolution. Maurice was captured and forced to watch the execution of his five sons before he himself was killed.
Maurice was one of the greatest emperors in the 1000-year history of Byzantium. He reformed military law. He stabilized borders. He wrote the Strategikon, a manual that would influence generals for centuries.
But he violated something older than empire. He violated trust.
And that mistake did not begin in 602. It began more than one million years ago.
The Deep Origin of Trust
Between 1.5 million and 800,000 years ago, our ancestor Homo erectus began forming long-distance trade networks. Tools, pigments, and crafts moved across landscapes. Groups encountered one another not only in conflict, but in exchange.
Trade requires something dangerous: delayed reciprocity. You give now and trust they will give later. That shift changed everything.
Neural Foundations
To sustain exchange, new neural capacities strengthened. The prefrontal cortex supported planning and self-regulation. Temporal and parietal regions supported perspective-taking. Limbic systems integrated emotion with valuation and memory. Together, these systems enabled self-awareness, self-identity, empathy, and a theory of mind.
We should remember that trust behaviors emerged well before true iconic language. For H erectus, learning happened by observation and patterns of repetition. Physical presence of a well-known individual could signal safety. Repeated and good exchanges built a trust & trade network. Bad exchanges signaled an enemy.
For over half a million years, and across Africa and Asia, the H erectus cultures mastered peaceful exchange. Over time, trade cultures would out-compete the smash-and-grab cultures that did not, or could not, participate in exchange networks. Trust & trade became an adaptive advantage.
The Four Trust Behaviors
From these deep origins we can extract four foundational behaviors. Each of these were built when our very lives depended on trustful relationships between groups of people.
First, know your role. Exchange requires identity and presence. Your partner must recognize who you are and what you contribute.
Second, show authentic empathy. Observe needs. Respond clearly and visibly.
Third, anticipate reactions. Theory of mind allows you to imagine how your exchange will be valued as beneficial.
Fourth, repeat and respect transaction patterns. How, when, and what. Trust is built by consistency and tradition.
These are not soft skills. They are evolved tendencies refined over hundreds of thousands of years. Every soldier in Maurice’s army carried these neural systems.
Maurice Through an Evolutionary Lens
At the critical moment of 602 along the northern banks of the Danube, Maurice failed to express trust behaviors.
He was absent, a distant authority rather than a visible partner. He ignored the suffering of his troops and misjudged their likely reaction. He broke longstanding cultural expectations of payment and winter return.
To the army’s evolved social brain, Maurice shifted categories. He moved from trusted partner to villain. Once that reclassification occurs, outcomes change quickly.
The mutiny was political, but the trigger was biological.
Trust in the Modern Workplace
Modern collapses follow similar patterns. When leaders break implicit exchange agreements, show indifference to team stress, disappear from shared experience, or violate established norms, trust erodes rapidly.
Teams fragment. Startups implode. Customers withdraw.
By contrast, organizations that scale trust through transparency, empathy, and consistent exchange expand faster and endure longer. Trust reduces transaction costs. It increases coordination speed. It multiplies creative exchange.
Trust is not a moral decoration. It is an evolutionary technology.
The Foundation Layer
In the Working Origins timeline, Trust & Trade followed earlier adaptations of emotional drives and social bonding. It preceded language, writing, law, and formal institutions.
Trust is the platform layer beneath every advanced workplace behavior: instruction, belief, agile cultures, education, and modern governance. Remove trust and the stack collapses.
Maurice built reforms. He wrote manuals. He structured law. But for one key moment, he neglected the layer beneath them — a layer under construction for more than a million years.
Takeaways
Today a workplace leader should ask questions Maurice did not. Where in the network of partners, suppliers, customers, and teams are durable patterns of trust? Where is trust quietly eroded by broken promises or one-sided exchange?
But this is not only a leadership concern. Each of us builds a career through trust. Promotions, sales, alliances, partnerships, and even hire-fire decisions are shaped by visible patterns of identity, reliability, and mutual gain.
Modern tools amplify both trust and its absence. Video calls, short-form text, chat, AI agents, and labor-saving automation reduce physical presence — one of the oldest trust signals we possess. We must compensate intentionally.
Every scam and con exploits the deep origins of trust. They hijack empathy, familiarity, and reciprocity — instincts that evolved long before contracts or cybersecurity.
Here are the key points.
One: trust is foundational to every successful workplace and trade network.
Two: trust is built through consistent patterns of role, presence, identity, and mutual benefit.
In the next post, we’ll move forward along the ESTIMATE timeline to the rise of instruction and iconic language — the adaptation that allowed trust to scale beyond sight and repetition.
Until then, remember the Working Origins motto:
Working together well is the most human thing we ever do.
