Professor Green says he values coworkers and friends who challenge him, then offers a compact distinction: before an idea has been challenged and defended, it is not yet a settled opinion. The method is to state the proposed direction, invite someone to question it, and explain why it should stand. That explanation exposes assumptions, evidence gaps, and borrowed certainty. The originator can then revise the idea or commit to it with a reason that survived scrutiny. The purpose is healthy challenge rather than reflexive opposition or consensus theatre. It is especially useful around leaders, whose status can make colleagues default to agreement. A decision earns commitment through tested reasoning, not through the speaker's authority alone.

Core principles
- 01An unchallenged belief has not earned commitment
- 02Healthy disagreement clarifies the reason behind a choice
- 03Explaining a position tests whether it can withstand scrutiny
- 04Strong colleagues challenge rather than merely agree
How to run it
- 1
State the idea
Present the proposed direction and the outcome it is meant to produce without pretending it is already settled.
Pro tip Label early thinking as a proposal.
- 2
Invite challenge
Ask a credible colleague to question the premise, evidence, and expected result.
Pro tip Give explicit permission to disagree with the highest-status person.
Watch out Challenge should test the idea, not attack the person.
- 3
Defend the reasoning
Explain why the direction should work and identify the assumptions carrying the conclusion.
Pro tip Name the evidence that would make you reverse course.
- 4
Revise or commit
Update the proposal when the challenge exposes a weakness, or commit when the reasoning remains persuasive.
Pro tip Capture the final rationale so later results can be compared with the original assumptions.
In the wild
Green imagines proposing that a team move in a particular direction. A colleague asks whether he really believes it. By explaining why he is willing to stand behind the choice, he tests whether it is a reasoned opinion rather than an unexamined belief.
→ The team receives a decision with a visible rationale instead of an authority-driven instruction.
Common mistakes
Hiring only agreement
A team that treats the leader's first thought as correct removes the mechanism that tests it.
Confusing challenge with obstruction
Useful challenge examines the proposal and advances the decision rather than opposing everything by default.
Is it for you?
Best for
Reversible team and creative decisions where informed colleagues can test the reasoning.
Not ideal for
Immediate emergencies where debate would create harmful delay or decisions requiring specialist evidence absent from the room.
