The Most Dangerous Assumption in the Room

I want to tell you about the time I was my own worst lawyer.

---

The accident wasn't dramatic in the way you might imagine. I had pneumonia. I passed out at the wheel. I drove my car into a fully loaded double cement hauler and was off work for months — bruised chest, collapsed lung, the pneumonia still working through me. The physical recovery was its own story. But the part that stayed with me was what happened in court.

I was charged with careless driving. In Ontario, the legislation doesn't leave much room for nuance: if you are knowingly unwell and you get behind the wheel, you have accepted responsibility for what follows. When the officer asked me what happened at the scene, I told him I was sick. I had, in legal terms, confessed.

I showed up to court without a lawyer. I brought my medical records. My assumption — held with complete confidence — was that this was essentially administrative. A formality. How can you be held responsible for getting pneumonia? The medical records were my defense. I remember calling my husband at the lunch break and telling him my lawyer was an idiot. My lawyer was me.

What I hadn't audited was the assumption underneath that certainty: that I understood what kind of room I was walking into.

I didn't.

The docket had about ten cases that day. Several were dismissed or rescheduled before lunch. By the time the afternoon session began, I had started to understand something I hadn't walked in knowing: I was the main event. The prosecutor had organized his entire day around me. The driver of the cement hauler — who I recognized, who was based in Kingston — had given up at least a day's pay to be there. The police officer was there too. The prosecutor was attentive to both of them in a way that told me exactly how much weight he had placed on this.

I had walked in thinking this was nothing. He had walked in thinking this was a win.

We had both pre-committed to our read of the situation before we arrived.

The difference was that I still had time to recalibrate. The judge was a temporary appointment — sharp, thorough, genuinely interested in whether I understood what I was navigating. The court reporter was paying attention in a way I noticed. At one point I was mid-explanation and I saw him shake his head, almost imperceptibly. I stopped talking. I changed direction. I didn't know exactly what I had been about to say that was wrong, but I trusted the signal.

This is the thing about reading a room: it only works if you're still open to what the room is telling you.

The judge's ruling was precise. She said I couldn't have predicted that my lung would collapse any more than I could have predicted a heart attack. I had taken reasonable precautions. She gave me my license back.

What she had done, without using this language, was find the place where the legislation's own assumption broke down. The law had pre-committed to a definition of negligence that didn't hold in my case. She audited it.

It is easy to apply the Assumption-Ground Audit to other people's assumptions. To the organization that commissioned an assessment after the direction was already chosen. To the leadership team that ran a consultation process that was really theater.

It is much harder to turn it on yourself.

I walked into that courtroom carrying an assumption I hadn't examined. I was so certain I understood the situation that I didn't think an audit was necessary. That certainty almost cost me my license.

The most dangerous assumption in the room is almost never the one you can see. It's the one you don't think to look for because you already know what's going on.

That's what makes Everyday Futurism a practice rather than a tool. A tool you pick up when you suspect someone else has pre-committed. A practice means you do the audit before you walk in — especially when you're most certain you don't need to.
