“I own this decision.”
Then ask: “Whose knowledge do I need before I make it?”
A better way to decide
Hold certainty lightly.
Have a view. Make the call. But stay curious enough to discover what you missed. The hardest decisions are full of sliders, and the right answer can change when you move one.
Confidence to act. Humility to listen. Room to change your mind.
Sound familiar?
The phrases that
close the room.
These can be fair questions or real constraints. Used as conversation stoppers, they end the inquiry just when it matters most. Try the next question instead.
“That’s my red line.”
Then ask: “What makes it non-negotiable, and what is still open?”
“We need a simple answer.”
Then ask: “What must we keep in view so the answer stays useful?”
“This feels academic. When do we get to practical delivery?”
Then ask: “What can we try now, and what assumption would that test?”
A deadline, an owner, a hard boundary or a simpler explanation may be exactly what the situation needs. Holding certainty lightly means explaining the reason and leaving room to test the parts that are still uncertain.
The manifesto
Five ways to
think better together.
Hold certainty lightly: make your view clear, then leave room for information that could change it.
01 /Name the constraint.
Name the constraint.
Don’t weaponise it.
If something is fixed, explain why, who set it, and what remains open. “My red line” tells people very little until you make the reason visible.
02 /Own the decision.
Own the decision.
Invite the challenge.
Accountability identifies who makes the call. It does not identify whose knowledge matters. Make it safe to question an assumption before the choice becomes a commitment. The evidence ↗
03 /Watch for the rush
Watch for the rush
to closure.
A clear answer feels good, especially under pressure. Ask what evidence you stopped seeking when the first plausible answer appeared. The evidence ↗
04 /Simplify the work.
Simplify the work.
Keep the important complexity.
We have limited attention. Use a tool to make the tradeoffs manageable, then check which differences the simplification erased. The evidence ↗
05 /Move the sliders.
Move the sliders.
Then decide.
Urgency, reversibility, risk and participation change the right process. Make a choice you can explain, and revisit it when the conditions change.
Life is full of sliders.
Holding certainty lightly means being clear about what you believe—and equally clear about what might change your mind.
Which parts are fixed, which are adjustable, and whose perspective have you not heard yet?
Decision helpers
Pick the question
you’re facing.
Small tools for decisions that deserve more than a slogan. Each one makes its assumptions visible so you can challenge the answer.

How should we decide?
Adjust urgency, reversibility, dispersed knowledge and buy-in to explore the right decision method.

How much agency should AI have?
Explore the continuum from deterministic workflow to bounded and more autonomous action, with human oversight matched to risk.
Open the AI agency helper →03 / Future helper
What are we treating as fixed?
Separate true constraints from preferences, assumptions and positions that can be negotiated.
On the drawing boardThe thinking behind it
Provocative words. Careful claims.
This manifesto draws on research into psychological safety, the need for cognitive closure, cognitive limits and group decision making. The research supports better questions and practices; it does not turn any one slogan or slider setting into a scientific rule.

A necessary exception: Some boundaries must be firm, including legal duties, safety limits and ethical commitments. The point is to identify the boundary precisely and explain its basis.
