How to Avoid Assumptions at Work: The ARC Method® vs. the Ladder of Inference

The short answer

To avoid assumptions at work, pause before you interpret, ask a clarifying question, and confirm what you heard before you act. The Ladder of Inference explains why we jump to conclusions. The ARC Method® (Ask, Respect, Connect), created by Bernadette Smith, gives you a simple way to stop climbing.

What the Ladder of Inference gets right

Organizational psychologist Chris Argyris described how fast our minds move. We see something, pick out a few details, add meaning, form an assumption, reach a conclusion, and act. All of that can happen in seconds.

Someone doesn’t answer your email. Your brain says they’re ignoring you. They might be busy, out of office, or waiting on information. The ladder helps you see the leap. It doesn’t always tell you what to say next.


Where the ARC Method® picks up

Knowing you made an assumption is step one. Doing something about it, in the moment, with a real person, is the hard part. That’s where ARC comes in.

Ask. Replace the assumption with a question. “Can you help me understand what you’re hoping for here?” A good question gets you clarity before the conversation goes sideways.

Respect. Take in the answer without judging it. You don’t have to agree to honor what someone shares. Respect keeps people talking, which is where trust starts.

Connect. Tie what you learned to a next step. “Here’s what I’m hearing, and here’s what I can do.” That is how understanding becomes action.

If you skip a step, the ARC falls. Ask without respect feels like an interrogation. Respect without connection stays polite and goes nowhere.


Using both together

Use the ladder to notice. Use ARC to respond.

  1. Notice the story you’re telling yourself. What do I know, and what am I filling in?

  2. Ask a question that tests it.

  3. Respect the answer, even when it surprises you.

  4. Connect it to a clear next step.

Where this matters most

Assumptions cost the most in client-facing moments: a sales call, a first meeting, a tough conversation with a customer. One wrong guess about someone’s background, role or needs can erode trust fast. Teams that practice ARC learn to recover quickly and keep the relationship intact.


Bring the ARC Method® to your team.

Our workshops give client-facing teams a simple way to replace assumptions with curiosity and recover when a conversation goes sideways.
