Professor Green describes noticing that he was finding the same kind of person in a different body and encountering similar relationship problems. His mechanism begins with pattern recognition: compare repeated situations and ask what stayed constant. He identifies himself as the common denominator, then shifts from projecting blame to examining his behaviours, insecurities, and defensive reactions. The purpose is not to assume responsibility for everybody else's choices; later in the episode he explicitly warns against doing that. It is to locate the part he can influence and change it through honest reflection and, when ready, therapy. The framework turns a vague complaint about other people into a bounded self-audit followed by one controllable behavioural change.

- 02Owning your behaviour is different from accepting blame for everything
- 03Understanding insecurity helps explain defensive responses
- 04Honesty is necessary for useful self-examination
How to run it
- 1
Spot the recurrence
Write down similar conflicts, relationships, or withdrawals that have happened more than once. Focus on the repeated shape rather than the different names.
Pro tip Compare situations separated by enough time to reveal a pattern.
Watch out A repeated harmful experience does not prove that you caused it.
- 2
Find the constant
Ask what remains present in every version of the problem, including your expectations, reactions, and choices.
Pro tip Use the common denominator as a hypothesis, not a verdict.
- 3
Name the behaviour
Describe what you actually do when the pattern appears, such as withdrawing, becoming defensive, or projecting blame.
Pro tip Prefer observable behaviour over identity labels.
- 4
Trace the trigger
Explore the insecurity or fear that makes the response feel protective. Be honest enough that the explanation can be tested rather than polished for appearance.
Pro tip A therapist or trusted person can challenge a self-serving account.
Watch out Do not use an explanation to excuse harmful conduct.
- 5
Change your input
Choose one response under your control and practise replacing it when the pattern next appears.
Pro tip Make the new response small enough to use during a real trigger.
In the wild
Professor Green says he kept finding the same person in a different body and seeing the same problems emerge. He asked what linked the stories, identified himself as the common denominator, and concluded that he needed to understand and change his own behaviours and insecurities rather than continue projecting them onto partners.
→ The recurring problem became a prompt for self-work rather than another round of external blame.
Common mistakes
Taking responsibility for everyone
The method is about your controllable contribution, not assuming ownership of choices another person made.
Using insight as an excuse
Understanding an insecurity does not remove the need to change the behaviour it drives.
Is it for you?
Best for
Recurring interpersonal problems where the person is willing to examine their own contribution honestly.
Not ideal for
Situations involving abuse or coercion, where self-reflection must not be used to transfer responsibility from the person causing harm.
