Option Space Expansion Prompt¶
Generative prompt — instantiates Informal Fallacy Diagnosis and Repair
Breaks a false binary by regenerating the live options a two-way framing suppressed.
Some arguments go wrong not in their logic but in the set of choices they present. Option Space Expansion Prompt attacks the false binary directly: when a claim frames a decision as "either A or B," it deliberately generates the third, fourth, and fifth options the framing has quietly dropped, restoring the real breadth of the choice. Its defining move is divergence — it manufactures rival framings of the decision to prove the "only two options" premise false. It does not score or rank the options it produces; its entire job is to widen the field so that a dilemma presented as exhaustive is shown not to be. It is generative and upstream: it supplies the missing alternatives that later evaluation will weigh, and it names the fallacy that suppressing them commits.
Example¶
An engineering lead argues in a planning meeting: "We either build the analytics dashboard ourselves or we buy the enterprise vendor's product — and building it will take two quarters we don't have, so we have to buy." Option Space Expansion Prompt is the intervention that unsticks this. It treats "build or buy" as a suspected false dilemma and prompts for rival framings of the same need: adopt an open-source dashboard and configure it; buy a lightweight tool now and revisit later; embed a third-party widget into the existing app; partner with another team that already has one; or ship a minimal internal version covering only the two charts anyone actually looks at. Each is a distinct framing of "how do we get analytics," not a point on a build-versus-buy line.
With five live options on the board, the argument's forcing move collapses — "we have to buy" was only compelling while the choice looked two-way. The prompt also names the defect: the original framing was a false dilemma, presenting two options as exhaustive when several others were available. It hands the widened set onward for evaluation; it does not itself decide which option wins.
How it works¶
- Detect the binary framing. Notice where the argument presents a decision as two mutually exclusive, jointly exhaustive options — the "either/or" that does the forcing.
- Prompt for rival framings. Systematically generate alternatives the binary excludes: hybrids and middle paths, reframings of the underlying goal, options that change the timeline, and the neglected "do something smaller" or "do nothing yet."
- Test each for genuine availability. Keep the options that are actually open (even if imperfect) and discard mere word-play, so the widened set is real rather than padded.
- Name the suppression. Where the original framing hid live options, mark it a false dilemma, and pass the expanded set forward for evaluation.
Tuning parameters¶
- Generativity aggressiveness — how hard you push to produce more options. Turned up, it surfaces creative middle paths but can manufacture nominal "options" no one would take; turned down, it may miss a real third way.
- Framing diversity — whether the prompts vary only the solution or also re-pose the underlying goal. Re-posing the goal unlocks the most novel options but risks wandering off the actual decision.
- Availability bar — how real an option must be to make the list. A high bar keeps the set credible; a low bar pads it with distractions that make the expansion look like obstruction.
- Stopping rule — when enough options have been generated. Too early re-collapses toward the binary; too late buries the decision under a sprawl of marginal choices.
When it helps, and when it misleads¶
Its strength is defeating the false dilemma, the framing that presents two options as the only ones so that rejecting one forces the other.[n1] By regenerating the suppressed alternatives, it restores decisions that a binary had artificially narrowed and reopens the space where a better-than-both option often lives.
Its failure mode is manufacturing illusory choice: padding the field with options that are not genuinely available, so a real and urgent binary is made to look falsely open and the decision stalls in analysis. Some dilemmas are true — occasionally there really are only two options — and treating every either/or as a fallacy is its own error. The classic misuse is using expansion as a delay tactic, generating endless "alternatives" to avoid committing to a hard but genuine two-way choice. The guarding discipline is to test each generated option for real availability before it counts, and to concede when a dilemma survives the expansion — when, after honest searching, the choice really is between just two.
How it implements the components¶
rival_framing_list— its primary output: the generated set of alternative framings that a binary suppressed, restoring the real breadth of the decision.fallacy_candidate_label— it names the suppression as a false dilemma when the original framing hid genuinely available options.
It does not record a comparison class or score options against a feasible standard — comparison_class_and_option_space_record belongs to Feasible Alternative Comparison; this prompt generates the suppressed options, while that mechanism records the field and judges a proposal against the best achievable one in it.

Editorial Notes¶
Form Classification¶
Form family: Interface, Display & Cue
Rationale: Option Space Expansion Prompt operates as a user-facing prompt, display, template, or perceptual cue that shapes attention and action at the point of use because it breaks a false binary by regenerating the live options a two-way framing suppressed.
Independent corroboration: The frozen evidence defines Option Space Expansion Prompt as 'Breaks a false binary by regenerating the live options a two-way framing suppressed', so its operative form is Interface, Display & Cue.
Review outcome: Independent reviewer agreement; high confidence.
Origin Attribution¶
Primary origin: Rhetoric
Origin pattern: Cross-disciplinary synthesis
Present-day reach: Universal
Rationale: Option Space Expansion Prompt is most directly rooted in rhetoric's traditions of argument, framing, ordered presentation, persuasion, and audience adaptation. The lineage fits its defining practice: Breaks a false binary by regenerating the live options a two-way framing suppressed.
Related originating lineages:
- Engineering & Design — Deliberately generating alternatives before selection is a core divergence move in design methodology.
- Innovation & Entrepreneurship — Ideation and opportunity-generation practices materially shaped prompts that break premature binaries.
- Philosophy — Option Space Expansion Prompt also draws materially on philosophy's traditions of conceptual analysis, ontology, logic, epistemology, and normative reasoning, which shaped this mechanism rather than merely adopting it as an application.
- Psychology — Option Space Expansion Prompt also draws materially on psychology and behavioral science's experimental study of judgment, learning, motivation, and behavior, which shaped this mechanism rather than merely adopting it as an application.
Review resolution: Authoritative-source research resolves the primary-origin disagreement in favor of rhetoric. Fallacies — Stanford Encyclopedia of Philosophy documents the formative practice or theory represented here. The retained alternate domains identify material co-development or translation, while current applicability is recorded separately as domain_reach=universal; origin_mode=cross_disciplinary_synthesis describes the historical relationship among lineages.
Attribution caveat: The compact prompt is an encyclopedia synthesis of widespread creative problem-solving practice.
Encyclopedia synthesis: The exact catalogued form synthesizes established practice rather than reproducing a single standard historical label.
Review outcome: Researched adjudication after independent review; medium confidence.

Notes¶
[n1] The false dilemma (or false dichotomy) presents two options as exhaustive and mutually exclusive when other options exist, so that ruling out one appears to force the other. This prompt refutes it by generating the excluded options and testing that they are genuinely available. ↩
