Role-Storming

Ordinary brainstorming stalls in two ways that have nothing to do with how much the room knows: people self-edit the odd idea because it would be theirs to own, and everyone stays trapped in the same default associations. Role-storming attacks both at once by changing WHO is generating. Instead of producing ideas as yourself, you adopt a specific assumed identity - “an eccentric inventor,” “a curious ten-year-old,” “a street artist,” “a rival founder” - and generate the ideas you imagine that persona would offer. The durable cognitive move, stripped of the slogan, is: generate divergent ideas while inhabiting a chosen non-self identity, using that identity as both an inhibition-lowering shield (the idea is the persona’s, not yours - ownership distance) and a distancing lens (the persona’s standpoint pulls you off your default associations - standpoint distance). The artifact is a persona-tagged idea list: candidate ideas attributed to each adopted role, so the distancing is auditable and the pile is ready for a downstream convergence step. This is a generation engine, not the fixed functional-lens evaluation the perspective family otherwise runs.

When to Use

Idea flow is being throttled by self-consciousness rather than a shortage of knowledge - the room where two confident voices set the frame and everyone else self-edits, or where the participants’ “serious” identity makes a playful or extreme idea feel unsafe to voice.
The thinking is fixated on one frame and a deliberately foreign standpoint (“how would a regulator / a child / a street artist see this?”) could break the fixation and surface candidates the default frame will not reach.
You want more and stranger candidates at the divergent stage, with a downstream convergence step to follow - role-storming only widens the pool, it does not pick.
A timid but possibly valuable idea needs a deniable owner so it can be said aloud at all.

When NOT to Use

You actually need a balanced appraisal of a decision, not more ideas. Generating “as the customer” is not the same as evaluating a choice through the customer’s interests. If the job is a multi-mode, convergent judgment of one option, route to think-parallel-perspectives-review (fixed functional lenses - facts, upside, risk, intuition, alternatives - over a single decision, producing a synthesis). Role-storming gives a creative pile, not a verdict.
You need genuine challenge, not role-played opposition. A persona arguing against the plan is a costume, and role-played dissent underperforms authentic dissent and can even harden the original view. If the goal is real challenge, route to think-authentic-dissent, which engineers for genuine minority dissent rather than impersonated objection.
The natural persona for the task is an inhibited or narrowing one. This is the method’s sharpest, evidence-backed failure mode - the one controlled adjacent result shows the effect FLIPS NEGATIVE with a rigid persona (an “eccentric poet” raised originality, a “rigid librarian” lowered it below baseline). Do not role-storm “as a cautious auditor” or “a risk-averse executive” to get ideas. Mandate an uninhibited or deliberately-foreign persona; forbid inhibited ones.
You want structured generation by other machinery. If the move is to negate a foundational premise, use think-assumption-reversal; to apply seven transformations to a seed, use think-scamper; to transfer deep structure from a distant domain, use think-far-analogy-ideation; to run silent parallel written generation, use think-brainwriting. Role-storming’s engine is identity-adoption specifically; reach for it only when the lever you want is who is generating.
The exercise is collapsing into caricature. When “the angry customer just complains” and the impersonation becomes the point, you are producing theatrical noise (and risk importing crude stereotypes), not ideas. The value is the distancing, not the performance.

Instructions

When asked to generate ideas via role-storming (or to break a stalled, self-censoring brainstorm), follow these steps:

State the generative question and confirm the fit. Write the one-line “how might we / what could we do” prompt the ideas should answer. Confirm the block is self-consciousness or fixation, not missing knowledge, and confirm a downstream convergence step exists. If the real job is to evaluate a decision, stop and route to think-parallel-perspectives-review; if it is to challenge a plan, route to think-authentic-dissent.
Choose 3-5 personas, each uninhibited or deliberately foreign. Pick assumed identities chosen for DISTANCE from the default frame - an unconventional maker, an outsider, a child, a rival, a user from a very different context. Apply the persona gate: each persona must be uninhibited or frame-breaking. Reject any inhibited or narrowing persona (“cautious auditor,” “risk-averse executive,” “rigid bureaucrat”) - it suppresses ideas instead of freeing them. Note in one phrase why each persona is expected to free or shift thinking.
Generate in character, one persona at a time. Inhabiting one persona, generate that persona’s candidate ideas for the question. Stay in standpoint: surface what THAT identity would notice or want, not what you would. Push past the first obvious idea per persona; the point is the ideas your own frame would not reach. Keep each idea a concrete candidate, not a complaint or a performance.
Tag every idea with its persona. Attribute each idea to the persona that produced it, so the distancing is auditable and a reader can see which standpoint generated what. This persona tag is what makes the artifact a role-storming output rather than an undifferentiated brainstorm.
Sweep for caricature and stereotype. Drop or rewrite any “idea” that is pure stereotype performance (the persona just complaining or mugging) or that imports a crude stereotype. Keep the distancing; discard the impersonation-as-point.
Do not converge here - hand off. Mark the list as a divergent pool for a separate convergence step. Optionally flag a few candidates that look most promising or most surprising, but do NOT rank, score, or down-select inside this artifact; that is a different move.
Emit the persona-tagged idea list artifact per references/TEMPLATE.md: the generative question, the chosen personas with their distancing rationale, the persona-tagged ideas, and the hand-off note. The deliverable is the tagged list, not a recommendation.

Output Format

Use the template in references/TEMPLATE.md. The deliverable is the filled persona-tagged idea list - the generative question, the personas (each justified as uninhibited or frame-breaking), and the candidate ideas each attributed to the persona that produced it, with a hand-off note to convergence. It is a divergent pool, not a ranked recommendation and not a per-lens evaluation. Never present it as a decision or a judgment.

Quality Checklist

Before finalizing, verify:

The generative question is stated in one line, and the block really is self-consciousness or fixation, not missing knowledge.
Every persona is uninhibited or deliberately foreign; no inhibited or narrowing persona (auditor, risk-averse executive, rigid bureaucrat) was used to generate.
Each persona carries a one-phrase rationale for why it is expected to free or shift thinking.
Every idea is tagged with the persona that produced it, so the distancing is auditable.
Ideas are concrete candidates, not complaints or stereotype performances; the caricature sweep was done.
The output stays divergent - no ranking, scoring, or down-selecting inside the artifact - and names the downstream convergence hand-off.
The artifact is not framed as an evaluation of a decision (that is think-parallel-perspectives-review) or as genuine challenge (that is think-authentic-dissent).
No overclaiming: this is a practitioner-grade, transferred-evidence generation aid; claim more and more-varied candidates, not a measured gain in idea quality (see evidence/dossier.md).

Evidence

Tier P (governing). Role-storming is a real, named, long-lived ideation heuristic with a clear origin (Rick Griggs, c. 1985) and a place in the creativity-facilitation canon (Arthur VanGundy), and it has a coherent mechanism story (ownership distance lowers inhibition; standpoint distance widens associations). That is the extent of what is directly supported: a respectable practitioner technique with a plausible mechanism. What the evidence does NOT support is the method’s own idea-count claim - there is no controlled or comparative study that measures role-storming itself against ordinary brainstorming or brainwriting; the “lowers anxiety / more ideas” framing is Griggs’s practitioner assertion, not a measured result, and any circulating effectiveness percentage traces to no primary source. The nearest real controlled evidence (Dumas and Dunbar 2016, the “creative stereotype effect,” M-tier) measures a DIFFERENT operation - stereotype priming before a solo divergent-thinking test - and its central result is conditional: an uninhibited persona helps, an inhibited persona HURTS. That result is counted here only as a boundary condition (it shapes the persona gate in the When-NOT wall), never banked as evidence FOR role-storming; borrowing its effect sizes would be exactly the transferred-evidence laundering this library exists to prevent. Transfer caveat: every adjacent result is from human subjects (lab undergraduates, VR participants); none studies role-storming performed by or with an AI agent. For a language model “adopting a persona,” the inhibition-release rationale (defeating social self-censorship) may not even apply, while the distancing-via-standpoint rationale might - this is untested. The skill ships as a divergence aid with a hard persona gate, never as a proven idea multiplier. Full grading, sources, and caveats: evidence/dossier.md.

Deep dive: worked example

A full worked run (the shared Northwind scenario)

Persona-Tagged Idea List - Worked Example

A completed run of the role-storming skill on a real, concrete decision. This is the quality bar a generated persona-tagged idea list should meet.

Uses the shared recurring scenario (Northwind, a B2B SaaS weighing a self-serve free-tier launch). Where think-parallel-perspectives-review would EVALUATE the free-tier decision through fixed functional lenses, and think-authentic-dissent would engineer genuine challenge to the plan, this skill does neither: it GENERATES a divergent pool of free-tier ideas by inhabiting non-self personas, then hands the pool to a separate convergence step. See docs/internal/AUTHORING.md.

This is a divergent pool. The ideas below are NOT ranked or down-selected. Every persona is uninhibited or deliberately foreign; no cautious-auditor / risk-averse-executive persona was used, because an inhibited persona suppresses ideas.

Generative question

Question: What could the Northwind self-serve free tier actually DO to get individual users to adopt it, love it, and pull their teams in - beyond the obvious “limited version of the paid product”?
Why role-storming fits: The team is not short on knowledge about its own product; it is stuck on the obvious framing (“free tier = paid product with caps”) and the senior voices keep steering back to packaging and conversion math. The block is fixation plus a little self-consciousness about “unserious” ideas, not missing facts. The pool will feed a convergence step (a think-decision-option-review on the strongest 6-8 candidates).

Personas (each uninhibited or deliberately foreign)

Persona	Why this persona frees or shifts thinking
A curious twelve-year-old who just wants to make something cool today	Strips away enterprise framing; surfaces play, instant gratification, and “why is this so complicated” candidates the adults self-edit
An indie game designer obsessed with onboarding and “juice”	Pulls associations toward delight, feedback loops, and first-five-minutes magic instead of feature caps
A guerrilla growth hacker with no budget and no shame	Breaks the “respectable B2B” inhibition; generates distribution and loop ideas the brand-conscious room would not voice
A community organizer who builds belonging, not funnels	Shifts the frame from “convert the individual” to “give the group a reason to gather,” reaching network ideas the conversion frame misses
A sci-fi novelist imagining how people work in 2035	Deliberately foreign standpoint; surfaces ambitious, agent-and-AI-native candidates today’s workflow frame would not reach

(Note the persona gate at work: a tempting “cautious procurement reviewer” persona was deliberately NOT used - it is inhibited and narrowing, and would have generated objections, not ideas. Procurement concerns belong in the downstream evaluation via think-parallel-perspectives-review, not in this divergent pool.)

Persona-tagged ideas

As the curious twelve-year-old

A “make something in 90 seconds” first run - you have a real, shareable result before you are ever asked to sign up properly. - (twelve-year-old)
Let me invite my two friends with one tap and we all see the same thing change live - working together is the fun part. - (twelve-year-old)
Stop hiding the cool stuff behind “upgrade.” Let me TRY the powerful thing once, today, so I know why it is worth it. - (twelve-year-old)

As the indie game designer

A guided first session that delivers one genuinely satisfying “whoa” moment in the first five minutes, with visible progress, not an empty dashboard. - (game designer)
Lightweight streaks and milestones for the individual (“you have shipped 5 things this week”) that make coming back feel good, decoupled from any paywall nag. - (game designer)
A “show your work” artifact the user can post outside Northwind (a polished summary card) - the reward IS the shareable proof. - (game designer)

As the guerrilla growth hacker

Every free-tier output carries a tasteful “made with Northwind” footer that is itself a link to the 90-second first run - the users do the distribution. - (growth hacker)
A public gallery of the best things free users made (opt-in), so the free tier doubles as the marketing site and as social proof for the timid new user. - (growth hacker)
Reward the user who brings in a teammate with something they actually want (more of the powerful feature), turning the free tier into a referral loop, not just a funnel. - (growth hacker)

As the community organizer

Give every free user a tiny shared “team space” by default, even solo - so the product is built around a group from minute one and pulling a colleague in is the natural next move, not an upsell. - (community organizer)
Host a low-key recurring “show and tell” where free users demo what they built; belonging, not features, becomes the retention mechanism. - (community organizer)
Let users adopt and remix each other’s setups (templates with a human name on them) so the free tier feels like a place with people, not a trial. - (community organizer)

As the sci-fi novelist

Assume the user expects an agent to DO the task, not a UI to do it in - the free tier’s “whoa” is “describe what you want and watch it happen,” sized so the agent is delightful but bounded. - (novelist)
The free tier quietly learns the user’s working style and offers to set up their teammates the same way - adoption spreads as configured environments, not seats. - (novelist)
A “future self” view that shows the user what their team’s work could look like in a year on Northwind - aspiration as an onboarding hook. - (novelist)

Caricature sweep

One growth-hacker “idea” was dropped because it had degraded into stereotype performance (spammy dark-pattern nagging) rather than a real candidate - that is the persona mugging, not generating. The community-organizer voice was watched so it stayed about product mechanics that create belonging, not a generic “build community” platitude. Nothing here imports a crude stereotype of a real group.

Hand-off to convergence

Status: divergent pool - NOT ranked, scored, or down-selected here.
Most surprising / promising to look at first (optional, not a ranking): the “shared team space by default” (community organizer) and the “90-second shareable first run” (twelve-year-old + game designer converging) both reframe the free tier away from “capped paid product”; the agent-first framing (novelist) is the most ambitious and the most uncertain.
Next step: take the strongest 6-8 candidates into a think-decision-option-review to evaluate them against effort, fit, and the conversion thesis - that convergence and judgment is explicitly NOT this artifact’s job.

Note how this differs from its neighbors on the same Northwind decision. A think-parallel-perspectives-review run would take ONE free-tier proposal and appraise it through fixed functional lenses (facts, upside, risk, alternatives) to reach a synthesis - a judgment, not a pile of ideas. A think-authentic-dissent run would engineer a genuine challenge to the free-tier plan, not a costumed objection. This role-storming run does neither: it inhabits five non-self identities purely to GENERATE candidates the default frame would not reach, tags each idea with the standpoint that produced it, and refuses to rank or decide - it widens the pool and hands it off. The deliverable is a tagged divergent pool, not an evaluation and not a challenge.

1. The mechanism (what actually does the work)

Role-storming is an ideation method: instead of generating ideas as yourself, you adopt a specific assumed identity - “answer as an eccentric inventor,” “as our most demanding customer,” “as a rival CEO,” “as a curious ten-year-old” - and produce the ideas you imagine that persona would offer. The claimed payoff has two parts that the honest description must keep separate, because they are two different mechanisms wearing one name:

Inhibition-release through ownership distance. Speaking “in character” detaches the idea from the speaker - it is the persona’s idea, not yours - which is supposed to lower the social anxiety and self-censorship that suppress odd suggestions in a group. The product is more ideas, and in particular more ideas people would have been too self-conscious to voice as themselves.
Construal distance through a foreign standpoint. Inhabiting someone unlike you is meant to pull you out of your default associations and into the persona’s, surfacing ideas your own frame would not reach. The product is different ideas, semantically further from the obvious.

The durable cognitive move, stripped of the slogan, is: generate divergent ideas while inhabiting a chosen non-self identity, using that identity as both an inhibition-lowering shield and a distancing lens. The artifact is a persona-tagged idea list - candidate ideas attributed to each adopted role. That persona-as-generation-engine is what distinguishes it from its neighbors; it is not the fixed functional-lens evaluation that the perspective family otherwise runs. It pairs naturally with a downstream convergence step, because on its own it only widens the pool.

2. Lineage

The technique is attributed to Rick Griggs (R. E. Griggs), who coined “rolestorming” around 1985 while a productivity and training manager at National Semiconductor and Intel; he framed it as a fix for the inhibition and first-idea conformity he saw stalling ordinary brainstorms. It entered the creativity-facilitation literature through Arthur B. VanGundy, who described and catalogued it (see 101 Activities for Teaching Creativity and Problem-Solving, 2005, and his earlier creative-problem-solving texts).

“Rolestorming / role-storming” is a generic descriptive term in common use - no trademark, no attribution required beyond crediting Griggs and VanGundy - so this entry is documented descriptively and is not flagged as branded. The attribution string credits Rick Griggs (and VanGundy for cataloguing it) as lineage.

3. What the evidence shows, and what it does NOT show

The honest grade for role-storming’s stated move - “generate ideas while adopting another identity” - is P (practitioner), and this dossier has to be careful, because role-storming is a case where a genuinely M-tier result sits one step away and is easy to misattribute to it. This holds the prior catalog tier (P) rather than overturning it.

What the record supports. Role-storming is a real, named, long-lived ideation heuristic with a clear origin (Griggs, mid-1980s) and a place in the creativity-facilitation canon (VanGundy). As a stance it is plausibly useful, and there is a coherent mechanism story (ownership distance lowers inhibition; standpoint distance widens associations) that is consistent with established lines of research. That is the extent of the directly supported claim: a respectable practitioner technique with a plausible mechanism.

What the record does NOT support, and the laundering trap. There is no controlled or comparative study locatable that measures role-storming itself - no RCT, no nominal-group comparison testing whether role-storming produces more or better ideas than ordinary brainstorming or brainwriting. The qualitative claims that it “lowers anxiety” and yields “more creative ideas” trace to Griggs’s own practitioner assertion, not to a primary measurement. The studies that do get cited to make role-storming look evidence-backed measure adjacent operations, and attaching their robustness to role-storming would be exactly the transferred-evidence laundering this library exists to prevent:

Dumas and Dunbar (2016), “The Creative Stereotype Effect” (PLOS ONE; Study 1 N=96, Study 2 N=105) is the nearest real evidence and is M-tier in method (controlled, two studies, real effect sizes: within-subjects fluency d=.84, originality d=.67). But it measures a different operation than role-storming: a single person imagines an “eccentric poet” or “rigid librarian” immediately before a solo Alternative Uses Task, and the dependent measures are AUT fluency and originality - it is stereotype priming on a standard divergent-thinking test, not role-storming as a group ideation method, and the authors never call it role-storming. Worse for the candidate, its central result is conditional: the uninhibited persona helps, the inhibited persona hurts (the librarian condition fell below control). It therefore cannot be banked as evidence for role-storming; it is evidence for a boundary condition role-storming usually ignores, and it is what the When-NOT persona gate is built around.
Lo and Hsu (2025), Scientific Reports - embodying a dissimilar VR avatar improved insight problem solving versus a similar avatar, interpreted through psychological distance. Adjacent and supportive of the distancing mechanism, but it is avatar embodiment in immersive VR on insight puzzles, not persona-driven divergent ideation, and not role-storming.
Galinsky and colleagues on perspective-taking, and construal-level theory (Trope and Liberman) on distance raising abstraction and creativity, supply the theoretical backing for “a foreign standpoint can free thinking,” but they study debiasing and abstract construal, not the role-storming procedure or its idea-count claim.

Borrowing the Dumas-Dunbar d-values, or the avatar and construal-level results, to lift role-storming to M would be laundering a cousin’s robustness onto a move the cousin did not test - and in this case the cousin actively flags a failure mode the candidate does not control for. The conservative governing grade is therefore P: a recognized practitioner technique with a plausible, partially-evidenced mechanism, no direct controlled evidence for its own idea-generation claim, with the M-tier creative-stereotype work explicitly not counted toward it.

4. Transferred-evidence flag (required honesty for this library)

Every adjacent result above is from human subjects (undergraduates in lab tasks, VR participants on insight puzzles). None studies role-storming, in any form, performed by or with an AI agent. The evidence is transferred from human contexts and not validated for AI-augmented use, which independently caps the grade at P. For a language model “adopting a persona,” the two mechanisms may not transfer equally: the inhibition-release rationale (defeating social self-censorship) may not even apply to a model that has no social anxiety to release, while the distancing-via-standpoint rationale (a foreign standpoint shifting associations) might - this is untested. The AI value is mechanical and modest: an agent makes the method cheap to run, can hold several distinct personas in parallel, enforces the persona gate (uninhibited or deliberately-foreign personas only), and produces a durable, inspectable, persona-tagged artifact - benefits that do not depend on any contested outcome claim. The skill ships honestly as a P-tier divergence aid with a hard persona gate, never as a proven idea multiplier.

5. Excluded figures

No primary quantitative effect for role-storming exists in the sources reviewed; the “more ideas / lowers anxiety” claims are practitioner assertions attributable to Griggs, not measured results, and are reported here as claims, not facts. Any percentage-style effectiveness figure for role-storming circulating in popularizations traces to no primary source and is excluded from the grade. The Dumas-Dunbar effect sizes are reported only as evidence about the adjacent creative-stereotype operation, not as role-storming’s effect, and are never transferred to role-storming.

6. When it works / when it fails (drives the eval negative cases and “When NOT to Use”)

Works best when:

A group’s idea flow is being throttled by self-consciousness rather than by a shortage of knowledge - the room where two confident voices set the frame and everyone else self-edits, or where the “serious” identity of the participants makes a playful or extreme idea feel unsafe to say aloud. Putting people behind a persona gives the timid idea a deniable owner.
The thinking is fixated on one frame and a deliberately foreign persona (“how would a street artist / a regulator / a child see this?”) can break the fixation.
More and more-varied candidates are wanted at the divergent stage, with a downstream convergence step to follow.

Fails or misleads when (poor-fit / anti-patterns):

The persona is an inhibited one. This is the method’s sharpest, evidence-backed failure mode. The one controlled result in the vicinity (Dumas and Dunbar 2016) shows the creativity boost is conditional on an uninhibited stereotype: imagining “an eccentric poet” raised fluency and originality, but imagining “a rigid librarian” lowered them below control. Role-storming as commonly taught lets participants pick any relevant identity - “a senior executive,” “a cautious auditor,” “an irate customer” - several of which are stereotypically inhibited or narrowing. Chosen badly, the persona suppresses ideas instead of freeing them. The skill therefore mandates an uninhibited or deliberately-foreign persona and forbids inhibited ones.
It is mistaken for evaluation. Generating ideas “as the customer” is not the same as evaluating a decision through the customer’s interests. If the job is a balanced, multi-mode appraisal of a choice, the fixed functional lenses of a parallel-perspectives review are the tool; role-storming will give you a creative pile, not a judgment. Route to think-parallel-perspectives-review.
It is mistaken for genuine dissent. A persona arguing against the plan is role-played opposition. The decision literature is explicit that role-played dissent (devil’s advocacy) underperforms authentic minority dissent and can even harden the original view (Nemeth 2001); if the goal is real challenge, engineer for genuine dissent, not a costume. Route to think-authentic-dissent.
The caricature substitutes for the work. Personas can collapse into shallow stereotype performance (“the angry customer just complains”), producing theatrical noise rather than ideas, and can import or reinforce crude stereotypes. The value is the distancing, not the impersonation; when the impersonation becomes the point, the exercise degrades.

7. Why it is a skill here (distinctness vs the named neighbors)

Verdict: Build - a documented entry that clears the distinctness bar on mechanism yet stays low-priority on conditional, transferred evidence.

The Build burden is to name one distinct, durable cognitive move that no shipped skill produces, and to show no existing skill (or chain) already produces it. Role-storming meets that burden on the mechanism, narrowly:

The closest shipped skill is think-parallel-perspectives-review, and it does NOT subsume the move. Parallel-perspectives runs a fixed set of functional lenses (facts, upside, risk, intuition, alternatives, process) over a single decision to produce a balanced evaluation with a synthesis. Its lenses are modes of thought, and even its stakeholder absorption walks a proposal “through each affected party’s eyes” for appraisal. Role-storming differs on all three axes: the lens is an arbitrary assumed identity chosen for distance, not a fixed functional checklist; the purpose is divergent idea generation via inhibition-release, not convergent balance; and the artifact is a persona-tagged idea list, not a per-lens review. The genuine shared element is only the abstract instruction “take more than one viewpoint” - the same family resemblance that loosely links the whole perspective family - which sits below the working-mechanism overlap ceiling once the generation-vs-evaluation purpose and the identity-vs-function lens object are accounted for. Notably, this is exactly why role-storming is not folded the way persona/role evaluation rituals were: those are genuinely redundant with parallel-perspectives, whereas role-storming is a generation engine parallel-perspectives does not run.
No shipped ideation skill owns the engine. The divergent-ideation family generates by different machinery: think-assumption-reversal negates foundational premises; think-brainwriting runs silent parallel written generation; think-scamper applies seven transformations to a seed; think-far-analogy-ideation transfers deep structure from distant domains. None generates by adopting an identity to lower self-censorship and shift associations. So role-storming’s engine is not a mode of any single shipped ideation skill, which is what a fold would require.
It is not a recipe. Role-storming is one move (inhabit a persona, generate in character), not a fixed chain like skill-A-then-skill-B; there is no sequence of two shipped skills whose composition is “persona-driven inhibition-release ideation.” So Build, not Recipe.

What keeps the evidence honest rather than confident: many shipped skills are P, so P alone does not disqualify it, but role-storming’s P is unusually thin and conditional. Its own idea-generation claim has zero direct controlled support, and the single strong adjacent result (Dumas and Dunbar) shows the effect flips negative with an inhibited persona - a failure mode the open “pick any relevant identity” method does not guard against. The library has also recorded a consistent skepticism toward role-play-based perspective methods (think-authentic-dissent was built precisely because role-played dissent underperforms genuine dissent). Role-storming survives that skepticism only because its purpose (generation) and artifact (persona-tagged idea list) are not the ones those folds already cover - and it ships only because a builder can hard-wire the when-NOT wall (mandate an uninhibited or deliberately-foreign persona, forbid inhibited/narrowing ones, route evaluation to think-parallel-perspectives-review and genuine challenge to think-authentic-dissent) into the artifact so the method cannot be cargo-culted into its own failure mode.

8. Output artifact

The skill must emit a persona-tagged idea list, not prose: the generative question; the chosen personas (3-5), each justified in a phrase as uninhibited or frame-breaking; the candidate ideas, each attributed to the persona that produced it; and a hand-off note marking the list as a divergent pool for a separate convergence step. The list is never ranked, scored, or down-selected inside this artifact, and is never framed as an evaluation of a decision or as genuine challenge.

Excluded under the evidence rule: no primary source measures rolestorming’s own effect on idea quantity or quality; the “lowers anxiety / yields more creative ideas” framing is Griggs’s practitioner claim, not a measured finding, and any circulating effectiveness percentage traces to no primary source and is not counted toward this entry’s grade. The Dumas-Dunbar effect sizes are counted only as evidence about the adjacent creative-stereotype operation, never transferred to rolestorming.
