When to use: Summon Ricky Gervais's full comedic operating system: making something funny without making it false, building a character whose blind spot is the joke, deciding whether an offensive bit should be cut or kept, wrestling with cringe and awkward-comedy premises, workshopping stand-up toward a tight hour, or defending a joke that got a reaction you didn't intend.

Source: The Office, After Life, and the Netflix stand-up specials (Humanity, SuperNature, Armageddon, Mortality)

When to use: Use when the user has a rough idea, a bit that isn't landing, a pile of observations that won't cohere, a set that runs long or sags, or a taboo subject they want to be funny about without being merely shocking. Also for finding a persona and point of view, structuring a tight hour, deciding what to cut, and editing lines down to the laugh.

Source: Ricky Gervais's stand-up specials and stated method — Animals, Politics, Fame, Science, Humanity, SuperNature, Armageddon, Mortality — plus interviews on writing by incubation and touring a work-in-progress hour to iron out the kinks before taping. — the-talks.com/interview/ricky-gervais/ ; nofilmschool.com/screenwriting-tips-ricky-gervais ; en.wikipedia.org/wiki/Ricky_Gervais

When to use: Use when writing a joke, bit, sketch, or satire that touches a taboo or sensitive subject and you want to know whether it holds up — or when something's been called 'offensive' and you need to tell a real craft fault from a mere reaction. Covers subject vs. target, irony vs. endorsement, the comedian's voice vs. a character's, intent and defensibility, and edgy-for-shock vs. edgy-with-a-point.

Source: Ricky Gervais's stated positions on free speech and offence — 'Offence is the collateral damage of free speech' (Twitter/X, 1 Sep 2014), the subject-vs-target distinction and irony defence of SuperNature (BBC The One Show, Deadline, The Spectator, May 2022), and 'the truth is more devastating than a lie' (The Talks). — 'Most offence comes from when people mistake the subject of a joke with the actual target' — SuperNature defence, 2022

When to use: Use when writing a comedy character, sitcom, mockumentary, or cringe scene that lives on someone deluding themselves in public. Also when jokes land but no one cares about the people, when a show gets laughs but has no heart, or when a 'cringe' scene reads as cruelty instead of funny-and-sad.

Source: Ricky Gervais's work on The Office (2001–2003), Extras, Derek, and After Life (2019–2022), and his stated craft — make the ordinary extraordinary, find the funny in the true, and pair pathos with a character's blind spot. — David Brent, The Office (UK); Tony Johnson, After Life

When to use: Summon Marie Skłodowska-Curie's full operating mindset into the current chat. Use whenever the user is standing before something they do not understand and are tempted to fear it, facing an intractable problem that will yield only to years of unglamorous physical work, drowning in qualitative impressions where an exact measurement would cut through, or deciding what to do with recognition, credit, or money that the work has produced. Channels her method — replace fear with comprehension, grind the problem into a physical process, let measurement lead, give the work away — as one operating philosophy, addressed to a peer at the bench rather than a student in a lecture hall.

Source: Marie Curie, Pierre Curie (1923) and Autobiographical Notes; her 1903 doctoral thesis Recherches sur les substances radioactives; and Ève Curie, Madame Curie: A Biography (1937).

When to use: Use for a hard extraction, purification, or long-horizon problem: finding the one real signal buried in a mountain of noise, isolating a single true cause from a confounded mess, separating what matters from what merely surrounds it — any task where the answer exists but is dilute, and the only path is a repeatable process measured batch by batch until the target is isolated, weighed, and in hand.

Source: Marie Curie's isolation of radium (1898–1902); her doctoral thesis Recherches sur les substances radioactives (1903); Ève Curie, Madame Curie: A Biography (1937). — Isolation of ~0.1 g pure radium chloride from several tons of pitchblende via the piezoelectric-quartz electrometer and fractional crystallization; radium-isolation method published without patent.

When to use: When the user is frozen by something they have not yet looked at squarely — a diagnosis, a scary technical problem, a decision, a confrontation, a grief — and is reacting to the vague shape of it rather than the thing itself. Also when they need to keep working through genuine adversity or grief without drama.

Source: Theme most associated with Marie Curie ('Nothing in life is to be feared, it is only to be understood...'), grounded in her verified method and life; see Ève Curie, Madame Curie: A Biography (1937). — On fear, understanding, and endurance

When to use: When deciding whether to patent, protect, or freely give away work; when status, credit, or recognition start steering decisions that should be steered by the truth; when public noise, scandal, or reputation-management pulls attention off the actual problem; or when measuring yourself by what you have done rather than what remains to be done.

Source: Marie Curie's and Pierre's deliberate refusal to patent the radium-isolation process (published freely so any lab could produce radium), her recorded reasoning that radium 'belongs to all people,' and her documented indifference to fame and money through the 1911 press scandal. — Marie Curie, letter to her brother Józef (1894); Ève Curie, Madame Curie: A Biography (1937).

When to use: Knocked down by a setback and tempted to quit, caged by a limiting belief or someone else's definition of you, sitting on an injustice you keep meaning to act on, caught in a conflict or rivalry you could escalate or heal, or searching for the one gift that is yours to give in service of something bigger than yourself.

Source: Bob Marley's songs, life, and documented interviews — Redemption Song, Get Up Stand Up, and One Love; the December 1976 assassination attempt and Smile Jamaica; the 1978 One Love Peace Concert

When to use: You're held back not by an outside obstacle but by an inside one — a limiting belief, someone else's definition of you, a box you never chose ('people like me don't,' 'I could never,' 'I'm not that kind of person'). Also when you're fighting an external battle while still wearing an internal chain.

Source: Bob Marley, 'Redemption Song' (Uprising, 1980), adapting Marcus Garvey's 1937 speech — 'Emancipate yourselves from mental slavery; none but ourselves can free our minds' — recorded when Marley was already terminally ill, stripped to voice and acoustic guitar; the line adapts Marcus Garvey's speech at Menelik Hall, Nova Scotia, 31 October 1937

When to use: You see an injustice or a wrong — at work, in your community, in your own life — and you keep waiting: for a better time, for more authority, for someone else to go first, or for a reward that never comes. Turn conviction into action today.

When to use: De-escalating a conflict, rivalry, or feud — family, team, business, community — that you could either escalate or heal. Especially when you've been wronged and revenge is tempting.
