How Ideas Spread

How Humans Have Always Shared News, Trust, and Influence Rick Slark | Slark Consulting Group

A few weeks ago, I found myself thinking about the ancient city of Ephesus.

Not the theology of it necessarily. Not even the letter written to the church there.

I was thinking about communication.

About how a message moved through the world before modern media existed.

A letter was written by hand. Carried by a person. Read aloud to a small group. Repeated in homes, marketplaces, workshops, docks, roads, and relationships. One person told another person. A merchant carried the idea to another city. A family repeated it over dinner. A traveler discussed it at a port.

And slowly, something spread.

That got me thinking about something I see constantly with startup and early-stage businesses.

Many of them are obsessed with reaching strangers.

Followers. Algorithms. Broad audiences. Mass attention.

Meanwhile, they often overlook the people already around them:

• family

• friends

• coworkers

• neighbors

• local groups

• former colleagues

• church members

• people who already know their name

And the more I thought about it, the more I realized something.

For most of human history, nearly everything important spread through small relational networks.

News. Religion. Commerce. Stories. Warnings. Reputation. Political movements. Business.

Almost all of it moved from person to person long before it ever reached the masses.

Technology changed the speed of communication. But I’m not convinced it fundamentally changed how human trust works.

Before Mass Communication

Long before newspapers, radio, television, or social media, human beings still needed to answer a basic question:

“How do we tell one another things?”

The answer was surprisingly simple.

People.

Anthropologists and historians have long noted that early human communities depended heavily on oral communication. Stories, warnings, customs, and knowledge were passed through tribes and families around fires, at meals, during travel, and through ritual.

Before written language became widespread, memory itself became a cultural tool.

Stories were repeated because they mattered.

Knowledge survived because communities carried it together.

Even after writing systems emerged, most communication still remained relational.

Many people throughout history could not read. Messages had to be spoken aloud, carried physically, interpreted by trusted individuals, or repeated through local networks.

In ancient villages, marketplaces functioned not only as centers of commerce but as communication hubs. Travelers brought news from distant regions. Merchants carried information along with goods. Sailors brought stories from ports. Reputation moved through conversation.

A blacksmith became known because people talked. A baker became trusted because neighbors recommended him. A craftsman survived because families spoke well of his work.

This was not called “marketing.” It was simply how human communication worked.

The Village Was The Original Network

When we think of communication today, we often think about scale.

Followers. Views. Reach. Audience size.

But for most of human history, communication happened at human scale.

Inside villages. Tribes. Households. Religious communities. Trade groups. Neighborhoods.

And something important happened inside these smaller circles: trust formed.

People learned who was reliable. Who exaggerated. Who delivered. Who failed. Who could be counted on.

That mattered because human beings rarely make decisions in isolation.

We learn socially. We evaluate socially. We imitate socially.

Even now, people still ask friends for recommendations before choosing:

• a contractor

• a restaurant

• a consultant

• a mechanic

• a church

• a doctor

• a coffee shop

Modern technology did not erase that instinct. It simply layered new tools over ancient human behavior.

Roads, Ports, and Messengers

As civilizations grew, communication networks expanded.

Road systems changed history.

The Roman road system, for example, connected vast portions of the empire and allowed goods, military movement, political authority, and ideas to travel farther and faster than before.

But even then, communication still moved through human carriers.

Messengers. Travelers. Merchants. Teachers. Soldiers. Families.

The city of Ephesus is a fascinating example.

Ephesus was one of the largest cities in the Roman world, likely holding hundreds of thousands of people at its height. It was wealthy, crowded, religious, commercial, and deeply connected to trade routes.

Ideas flowed constantly through the city.

And yet even there, communication remained relational.

Letters were carried physically. Messages were read aloud. Ideas spread through households, trade relationships, and trusted communities.

Christianity itself spread this way.

Not initially through giant institutions or mass broadcasting. But through people.

House churches. Meals. Friendships. Travelers. Merchants. Families.

A message moved from one small circle to another.

The Printing Press Changed Everything

Then came one of the great communication revolutions in human history.

The printing press.

Johannes Gutenberg’s movable type press dramatically expanded the ability to reproduce information at scale.

Books that once required painstaking manual copying could suddenly be produced in far larger quantities.

Ideas accelerated.

The printed Bible became enormously significant not only religiously but culturally because information could now move more broadly through society.

Literacy expanded. Pamphlets spread. Political movements accelerated. Knowledge became more portable.

And for the first time in history, communication began shifting from primarily local transmission toward scalable distribution.

That trend continued through:

• newspapers

• magazines

• telegraph systems

• radio

• television

• mass advertising

Eventually, businesses learned they could speak directly to enormous audiences.

Mass communication became normal.

And to be clear, this was not a bad thing.

Modern communication technologies have allowed:

• education to spread

• emergency information to travel quickly

• businesses to scale

• creators to reach global audiences

• communities to form across geography

We are wise to use these tools.

But I do think something subtle happened along the way.

Many businesses began assuming that broad reach itself was the goal.

The Modern Startup Problem

I work with many startup and early-stage businesses.

And one pattern appears over and over again.

A business launches and immediately begins trying to reach strangers.

They start asking:

• How do I grow followers?

• How do I go viral?

• How do I beat the algorithm?

• How do I scale attention?

Meanwhile, they may barely be communicating with:

• existing relationships

• local communities

• past coworkers

• neighbors

• former customers

• friends of friends

• local business owners

• referral sources

In other words, they often neglect the very relational networks through which human beings have historically spread trust and influence.

I’m not saying businesses should avoid broader marketing. Far from it.

I use social media. I write online. I understand the importance of visibility.

But I think many startup businesses accidentally reverse the historical pattern.

For centuries, most things spread from the inside out.

Today, many businesses attempt to begin from the outside in.

The Circle Problem

One of the most useful ways I’ve begun thinking about this is through three circles.

Circle 1: People Closest To You

These are:

• family

• friends

• neighbors

• coworkers

• existing relationships

• people who already know your name

Circle 2: Connected Relationships

These include:

• referrals

• friends of friends

• local organizations

• partnerships

• community overlap

• adjacent networks

Circle 3: The Broader Public

This is:

• strangers

• cold audiences

• mass social media

• broad advertising

• large-scale reach

There is nothing wrong with Circle 3.

The problem is that many businesses ignore Circles 1 and 2 while obsessing over Circle 3.

Historically, that is backwards.

Most durable businesses became known locally before they became known broadly.

Trust accumulated before scale did.

Technology Did Not Eliminate Human Nature

This is the important distinction.

I do not believe modern communication destroyed relational communication.

In many ways, it amplified it.

Look carefully at how people still behave online.

People:

• share podcasts with friends

• text recommendations

• forward newsletters

• join niche communities

• trust creators who feel personal

• buy from people they feel connected to

• ask for referrals in Facebook groups

• follow recommendations from people they know

Even inside digital systems, humans still navigate information relationally.

The tools changed. The scale changed. The speed changed.

But underneath it all, human beings still appear to trust through smaller circles.

That matters.

Especially for small businesses.

You Probably Need Fewer People Than You Think

This may be one of the most important realizations for startup owners.

Many businesses psychologically operate as though they need massive audiences to survive.

In reality, many small businesses would be transformed by:

• 10 excellent clients

• several strong referral partners

• one trusted community connection

• a handful of repeat customers

• a small but loyal network

A local CPA does not necessarily need millions of followers.

A consultant often grows through trust. A contractor grows through reputation. A therapist grows through referrals. A coffee shop grows through familiarity and community.

Historically, this was normal.

The village baker did not need global awareness. He needed local trust.

What This Means Today

I think modern businesses should absolutely use:

• websites

• email

• social media

• digital marketing

• podcasts

• online communities

But perhaps we should think differently about what these tools are actually for.

Maybe the goal is not merely to broadcast.

Maybe the goal is to strengthen and extend relational trust.

Maybe the internet did not replace human networks. Maybe it simply gave them new infrastructure.

And maybe the businesses that thrive long term are not merely the loudest.

Maybe they are the ones that become deeply known and trusted within connected circles of people.

Final Thoughts

For most of human history, news, trust, commerce, reputation, and influence spread through small relational communities.

Families. Villages. Roads. Ports. Markets. Households. Churches. Neighbors. Friendships.

Human beings learned through people.

The modern world gave us extraordinary communication tools, and we should use them wisely.

But perhaps the future of communication is not abandoning technology.

Perhaps it is remembering what humans have always trusted inside it.

So before you spend all your energy trying to reach thousands of strangers, it may be worth asking a simpler question:

Have you become known, trusted, and useful within the circles already closest to you?

Because historically, that is where most things began to spread.
