Every day, you make calls that no algorithm can make for you.
Not because the technology isn't there. It is. The models are extraordinary. They can process a thousand data points before you finish reading this sentence. They can draft your strategy document, surface patterns in your customer data, and generate three plausible scenarios for your Q3 forecast before lunch.
But they cannot tell you which scenario to believe. They cannot read the room when your CFO's hesitation means something the spreadsheet doesn't show. They cannot feel the weight of a trade-off between two values that both matter and pull in opposite directions. And they cannot decide, on your behalf, when the elegant, data-supported recommendation sitting in front of you is almost certainly wrong, because something in the situation doesn't fit and you can't yet say what it is.
That's judgement.
Judgement operates upstream of every decision you make. It determines whether you're even solving the right problem. It tells you the analysis is correct but the conclusion doesn't follow. It separates the leader who acts on data from the leader who hides behind it.
You use it every day. You've used it to build a career, lead a team, make calls under pressure that no spreadsheet could make for you. But you've almost certainly never examined how it actually works, where it breaks down, or what you can do to make it sharper.
AI is becoming the most powerful thinking partner you've ever had. The question isn't whether to use it. It's whether you're using it in a way that strengthens your judgement or quietly replaces it.
That’s what this masterclass is for.
It's built on peer-reviewed research in decision science and behavioural science, and on fifteen years of working with professionals and leadership teams on exactly this problem.
It's free. It takes about 60–90 minutes at your own pace. And it will change the way you think about the decisions you make and the way your team makes them. With and without AI.
What's inside
You'll start with a diagnostic that maps your judgement across four dimensions, showing you where you're strongest and where you're most exposed.
Then you'll see how two of the most common decision tools are almost universally misused, and how small tweaks can make them useful again.
You'll learn why knowing about cognitive biases and other traps doesn't protect you from them. You'll distinguish between those well-behaved traps are easily fixable, and the traps that no tool can fix on its own.
You'll go inside three organisations, a surgical team, an animation studio, and one of the world's largest technology companies, that faced deep judgement failures at scale and redesigned the conditions around their decisions. Not by making their people smarter, but by changing the systems in which those people worked.
And you'll leave with a practical set of tools for strengthening your own judgement and, importantly, making the change stick, not through willpower but through behavioural science.
Who is this for
You're good at what you do. You run things. You make consequential decisions under real constraints, with imperfect information, alongside other people. You don't need to be told that decisions matter.
What you might not have is a framework for the part of decision-making that sits upstream of the tools, the frameworks, and the data: the judgement that determines whether any of those are being used well.
This masterclass is for professionals who are ready to look honestly at how their judgement works and do something concrete about the parts that could be sharper, especially in a moment when AI is changing what good judgement demands.
After the masterclass, the Judgement Toolkit takes the system further.

After the masterclass, I keep thinking of my own examples from work where the traps and fixes apply. That's still going days later.

I could easily propose this as a paid workshop for the management team at work. There is real value in it."
