Begin from the assumption that the person in front of you is acting in reasonable faith. Not because you are gullible, but because, statistically and practically, it is true more often than not. The cost of being wrong is small. The cost of the opposite assumption — leading every interaction defensively — compounds over a lifetime.
What the default really costs you.
Most professional advice on dealing with people quietly assumes the inverse — that you should expect to be manipulated, lied to, or shortchanged, and design your behavior to prevent it. The advice is not wrong about the existence of bad actors. It is wrong about how often they appear.
When you carry the wrong default into a thousand small interactions a year, the price is invisible but enormous. Conversations get colder. Reasonable concessions stop being offered. People who would have helped you stop volunteering. You receive, over time, exactly the world you assumed you were already living in.
“Trust is not a reward you grant after extensive testing. It is the working capital that makes every interaction cheaper.”
What years of trades work actually shows.
After enough years on enough job sites, in enough living rooms, with enough vendors and crews and homeowners and adjusters, a clear pattern emerges. The overwhelming majority of people you encounter want to do right by you, or are at least willing to be persuaded to. The occasional bad actor stands out because they are the exception.
A small number of people will try to take advantage of you. They are not difficult to identify in time, and the damage they cause is almost always recoverable. The price of assuming everyone is one of them, in advance, is the loss of every relationship the truth would have allowed.
Trust without naivety.
Operating from this default does not mean abandoning judgment. It means starting with trust and verifying through behavior, not the other way around. You sign clear agreements. You document the work. You set clear expectations. And then you assume the person across from you intends to honor them.
When the assumption proves wrong, you respond — calmly, firmly, in writing. You do not generalize the failure outward. The next customer, vendor, or crew member is treated as themselves, not as a representative of the last one who disappointed you.
“Verify with systems. Trust with posture. The two are not in conflict.”
Why this is the foundation of every other principle.
Every other principle on this list — work ethic, curiosity, systems, respect — depends quietly on this one. You cannot build a team you do not believe in. You cannot teach someone you do not respect. You cannot lead a company by treating customers as adversaries.
Begin from the assumption that most people are good and the rest of the operating system becomes available. Abandon it, and you will spend the rest of your career building defenses against a world that was mostly trying to help you.
- 01Treat trust as working capital, not a reward earned after testing.
- 02Document and verify through systems — never through suspicion in conversation.
- 03Bad actors are real but rare. Do not generalize their behavior onto the next person.
- 04The price of the opposite assumption is invisible but compounds across an entire career.
- Isn't this naive in business?
- It would be, if it meant operating without contracts, documentation, or judgment. It does not. The principle governs posture, not procedure. The procedure stays disciplined.
- What about people who have been burned repeatedly?
- The right response is better systems, not a worse default. Write things down, set clearer expectations, walk away from patterns that keep producing the same result. The posture you bring into the next room should still be open.
