Gain/Loss Frame Comparison¶
Comparison probe — instantiates Framing Effect Audit
Presents a logically identical outcome once as a gain and once as a loss, measures how far the reframing moves preference, and decides whether both valences must be shown.
Gain/Loss Frame Comparison takes an outcome that is fixed in substance and expresses it in opposite valences — a gain versus a loss, survival versus mortality, a saving versus a cost, lives saved versus lives lost — then measures how far preference moves between the two. Its defining move is that the reframing is logically equivalent by construction (90% survive is 10% die), so any shift in choice is attributable to valence alone, not to a change in what is described. Because there is no neutral valence to fall back on, the mechanism ends not by finding the "right" frame but by deciding whether the effect is large enough that both valences must be disclosed.
Example¶
A hospital is drafting a decision aid for patients choosing between surgery and radiation for a particular cancer. The same one-year statistic can be written as "90 out of 100 people are alive one year after this surgery" or "10 out of 100 people die within one year of this surgery." Gain/Loss Frame Comparison builds both versions of the aid and, in patient testing, measures how the stated preference for surgery moves between the survival framing and the mortality framing. The two sentences are numerically identical, so a gap between them is pure valence effect — the loss framing makes surgery's risk loom larger and shifts some patients toward radiation.[n1] The probe reports the size of that swing, checks it against the threshold the team set for a consequential shift in a life-affecting choice, and — because neither "survival" nor "mortality" is the neutral truth — concludes with a rule: present both framings side by side rather than let one valence carry the decision.
How it works¶
- Build the opposite-valence pair. Write the outcome as a gain and as a loss from the same underlying figure, so the two versions are provably equivalent and differ only in direction.
- Measure the preference swing. Observe how choice or rated risk moves between the valences, isolating the valence effect because content is held identical.
- Judge against the threshold, then rule on disclosure. Compare the swing to a pre-set bar for a consequential shift; where it clears the bar, require both valences to be shown rather than picking one.
The distinguishing discipline is that it works the valence/direction axis of an equivalent outcome and resolves to a disclosure rule — it does not swap the reference a number is measured against, and it does not enumerate a family of reference variables.
Tuning parameters¶
- Valence pair choice — which opposing framings you test (gain/loss, survival/mortality, cost/saving, avoided-loss). Different pairs probe different reference points; the sharpest pair for the decision exposes the most.
- Materiality threshold — how large a preference swing counts as consequential. A strict bar treats small swings as material in high-stakes choices; a loose bar risks passing a steering frame as robust.
- Elicitation format — forced choice, rating, or willingness-to-act. Each surfaces the valence effect differently; forced choice is starkest but coarsest.
- Disclosure form — side-by-side both-valence, a single frame with a stated caveat, or rejection of a one-valence result. More disclosure is more honest but raises reader load.
When it helps, and when it misleads¶
Its strength is isolating the purest kind of framing effect — one where the alternatives are indisputably equivalent, so a preference reversal cannot be waved away as a content difference — which makes it the sharpest probe for risk communication and consent.
It can mislead if the two valences are not actually equivalent (a "cost" version that quietly adds a fee is a content change, not a reframing), and it invites run-it-backwards abuse: finding the valence that produces the wanted choice and shipping only that. It also tempts a team to treat one valence as the "real" number when neither is neutral. The discipline that keeps it honest is to verify equivalence before attributing a swing to valence, and to default to showing both framings when the swing is material rather than selecting the flattering one.
How it implements the components¶
Gain/Loss Frame Comparison realizes the valence-probe side of the archetype:
alternate_presentation_set— the gain-framed and loss-framed versions are the alternate presentations, equivalent by construction and differing only in valence.frame_effect_threshold— it sizes the preference swing between valences and tests it against a pre-set bar for a consequential shift.frame_disclosure_or_selection_rule— where the swing is material, it resolves to a rule (typically show both valences), since no single valence is neutral.
It does not enumerate the reference-variable family or certify a swap's scope with an equivalence_or_difference_record, nor build a framing_variable_inventory of baselines and denominators — that is Baseline Reference Swap. The separation is that a gain/loss comparison holds the number fixed and flips its *valence, whereas a reference swap changes the anchor the number is measured against and must prove the swap preserves scope.*

Editorial Notes¶
Form Classification¶
Form family: Experiment, Test & Rehearsal
Rationale: Gain/Loss Frame Comparison operates as a bounded trial, probe, simulation, or rehearsal that generates evidence from performance because it presents a logically identical outcome once as a gain and once as a loss, measures how far the reframing moves preference, and decides whether both valences must be shown.
Independent corroboration: The frozen evidence defines Gain/Loss Frame Comparison as 'Presents a logically identical outcome once as a gain and once as a loss, measures how far the reframing moves preference, and decides whether both valences must be shown', so its operative form is Experiment, Test & Rehearsal.
Nearest alternative: Assessment, Review & Assurance — Opposite-valence presentations deliberately vary framing to measure preference swing, beyond reviewing an existing disclosure.
Review outcome: Independent reviewer agreement; medium confidence.
Origin Attribution¶
Primary origin: Behavioral Economics
Origin pattern: Single lineage
Present-day reach: Multi-domain
Rationale: Tversky and Kahneman's prospect-theory experiments canonically established gain-loss framing reversals.
Related originating lineages:
- Psychology — Experimental cognitive and social psychology supplied the comparative framing paradigm.
Review outcome: Independent reviewer agreement; high confidence.
Notes¶
[n1] The gain/loss reversal is the classic framing effect of prospect theory (Tversky & Kahneman): people are risk-averse for gains and risk-seeking for losses, so a mathematically identical outcome described in survival versus mortality terms can flip a stated preference even though nothing about the outcome has changed. ↩
