Your Operating Assumptions Run the Company

A man sits down in my office. He runs a company with sixty people in it. He has not slept properly in three weeks. He says: “I think my business partner is working against me.”

I ask him what happened. He describes a meeting where his partner redirected a conversation, spoke over him twice, and then had lunch with a client without mentioning it. Each detail is accurate. Each one is verifiable. And together, they tell a story that has been keeping him awake since it happened.

But here is what I notice after fifteen years of sitting with people: those same three facts also tell at least four other stories. His partner was anxious about the client and handled it badly. His partner is conflict-avoidant and was trying to smooth things over. His partner forgot to mention the lunch because it was unremarkable to him. His partner was having a terrible week and lost his manners.

Every one of those explanations fits the data. But my client’s brain chose the threatening one — the betrayal — and locked it in before he left the car park. By the time he reached me, three weeks of confirmation bias had turned a plausible interpretation into a settled conviction.

This is not a failure of intelligence. He is exceptionally intelligent. It is how all human minds work. Your brain does not experience “facts.” It experiences selected meaning. And the selection is where most of the damage gets done.

What “Competing Truths” Actually Means

Your partner comes home and walks straight past you to the bedroom without a word. Here is what is true, simultaneously:

• “They’re angry with me.”
• “They had a day that emptied them out and they need ten minutes to become human again.”
• “They didn’t see me in the kitchen.”
• “They’re carrying something heavy that has nothing to do with me.”

Each statement is plausible. Each is consistent with the observed behaviour. But notice where they lead. The first produces a tight chest and a defensive opening line. The second produces patience and a cup of tea. Same moment, different truth selected, different evening — different relationship, compounded over years.

This is what I mean by competing truths: multiple legitimate descriptions drawn from the same set of facts. None of them are lies. They are genuine facets of a complex situation. The problem is never that one truth is wrong. The problem is that whichever truth gets foregrounded shapes everything that follows — your mood, your next sentence, your decisions, and eventually your sense of what kind of life you are living.

Your Mind Does Not Just Notice Truth — It Locks In a Story

Here is the sequence I see play out, over and over, with the people who sit across from me:

1. Truth selection. Your brain lands on one facet of the situation. (“He had lunch with my client without telling me.”)
2. Mindset formation. The selected truth becomes a lens — a set of beliefs and expectations that filters everything new. (“He’s positioning against me.”)
3. Confirmation bias. You start noticing evidence that fits and dismissing evidence that doesn’t. (“See — he was on his phone during my presentation too.”)
4. Action. You act in ways consistent with the mindset — withdraw, withhold information, build alliances, get cold.
5. Reinforcement. Your behaviour creates the very outcomes you feared. (“I pulled back, so he stopped including me. Confirmed: he was freezing me out all along.”)

This is how a single moment of truth selection becomes a self-fulfilling prophecy. Not because the initial truth was false — but because it was partial, and your brain treated it as total.

I have watched this sequence destroy partnerships, marriages, and someone’s relationship with their own child. The starting point is almost never a lie. It is a true thing, given too much authority.

Your mind aims a spotlight at one true detail and leaves the rest in darkness. Then it calls the spotlight “reality.”

How People Mislead with Truth — and How We Mislead Ourselves

If you can be misled by true information, then truth-handling matters more than most people realise. There are three modes worth understanding:

• Advocacy: Selecting truths to create a reasonably accurate impression for a constructive purpose. When I tell someone in crisis that they have survived every bad day so far, I am selecting a truth. I am not lying. I am choosing which facet to illuminate because it serves them. That is ethical.
• Misinformation: Spreading distortions unintentionally. A friend who says “Everyone thinks you’re wonderful” without checking is well-meaning, but feeding you unreliable data. They believe what they are saying. It is still a curated truth.
• Misleading: Selecting truths to deliberately create a false impression. A partner who says “I only raised my voice because you provoked me” is stating something that may be technically accurate — while selecting it to obscure a pattern they do not want examined.

Here is the part that matters most: your own mind can function like a misleader. Not maliciously. Automatically. It cherry-picks truths that justify retreat (“It went badly once, so it will go badly again”). It uses technically true data points to imply untrue conclusions. It is not lying to you. It is selecting evidence like a lawyer who only calls witnesses for one side — and you are the jury, and you do not know the other side exists.

Where This Shows Up in the Rest of Your Life

Once you see the pattern, you cannot unsee it. It is running in almost every domain.

Work: You present an idea and two people push back. Your mind selects “They think I’m out of my depth” and deletes “They were stress-testing the idea because they take it seriously.” You stop contributing in meetings. Six months later, you call it a culture problem.

Friendships: Someone cancels on you twice. Your mind selects “I’m not a priority” and skips “They are drowning and do not know how to say that.” You pull back. They notice and assume you have lost interest. The friendship fades, and both of you tell yourselves a story about why.

Your relationship with yourself: You look at where you are at forty and compare it to where you thought you would be. Your mind selects “I’ve fallen behind” and ignores “I survived things I didn’t expect to face, and I’m still here, still trying.” The first truth produces shame. The second produces something closer to dignity. Both are equally true.

The Truth Selection Audit

This is the practical centre of this post. Use it whenever you notice a strong emotional reaction and suspect your brain has welded itself to one interpretation too quickly.

A Necessary Caution

Competing truths is a powerful lens. It can also be misused, and I want to be direct about that:

• Do not use it to invalidate someone. “You’re just selecting a negative truth” said to someone who is hurting is not insight. It is dismissal with a psychological vocabulary. The point is never that someone’s truth is wrong. The point is that there may be more truth available than the piece they are stuck on.
• Do not use it to excuse genuine harm. Competing truths does not mean all interpretations are morally equivalent. Some behaviours are damaging regardless of how they are framed. If someone is treating you badly, the competing truth is not “maybe I deserve it.”
• If you are in acute distress, this is not your first step. The audit works when you have enough bandwidth to think. If you are at a nine out of ten, your job is to calm your body first — not to generate alternative interpretations. This tool works at a five or below.

Key Takeaways

• You can be profoundly misled without anyone lying to you — including by your own mind.
• Your first interpretation is a draft, not a verdict. Treat it that way.
• The sequence that causes most of the damage: truth selection → mindset → confirmation bias → action → reinforcement. By the time you reach the end, the original selection feels like established fact.
• Clean communication selects truths to clarify. Manipulation selects truths to control. Your own anxiety often does the latter while pretending to do the former.
• You do not need to find the “right” truth. You need to see that there are more truths than the one your brain handed you — and then choose the one you can defend and live inside without it costing you the things that matter.

If you want to stop being steered by whichever truth your mind grabs first, you have to go one level deeper: the assumptions that decide which truths get selected in the first place. That is the next post.
