The Interference Window
Your thinking is getting in the way, more than the situation is.
The Interference Window is a simple diagnostic tool for leaders and senior professionals who want to understand what is actually creating stress, and what to do about it.
Built on 30 years of research in psychological flexibility, and designed specifically for the workplace.
Most high performers already know this
The pressure does not always come from the workload. It comes from what your mind does with it. The story about what it means. The sense that something is at stake. The pull toward urgency when clarity would serve you better.
You have probably noticed that your most stressed moments are not always your hardest ones. And that on a good day, difficult things feel manageable. The situation did not change. Something else did.
That something is what this is about.
Every situation has two layers
There is what is happening. And there is what your mind adds to it.
The second layer — the judgements, the identity, the urgency, the resistance to how things are — is what creates interference. And interference is what creates stress.
This is one of the most replicated findings in psychological research. What is new is a simple way of seeing it in yourself, in real time, in the middle of a working day.
That is what The Interference Window does
The Interference Window
The window describes where you are at any point — based on how much your thinking is interfering, and how aware of it you are. You move through all four states. The aim is not to stay in one. It is to know where you are.
Suffering
Thoughts feel like facts. Things feel personal and overwhelming..Struggling
You can see your thoughts creating friction. You are not yet free of it.Engaging
Interference is reducing. You are responding rather than reacting.Flowing
Minimal interference. Action feels natural and clear.

Where this comes from
The Interference Window is built on Acceptance and Commitment Therapy — one of the most researched frameworks in behavioural science, with over 30 years of evidence behind it.
It was created by Simon Davie — a CEO with a decade of personal experience applying these principles to leadership and performance, and a conviction that the core insight was too useful to stay inside a therapy room.
The Interference Window is his attempt to make it accessible, practical, and relevant to the pressure that shows up in a working day.
