Describing an outcome in terms of gains or of losses shifts choices even when the underlying facts are identical, which means presentation is doing work that the evidence is not. Reaching different conclusions from the same information depending on how it is worded or presented — for example, '90% survive' versus '10% die.' *Example: 'This surgery has a 90% survival rate' feels far safer than 'a 10% chance of death,' though they're identical.* ## What it looks like **On food packaging** > 90% fat free. *Why it fails:* Identical to 10% fat, but the gain frame produces markedly more favourable judgements. Nothing about the product differs between the two descriptions. **In a medical consultation** > Ninety percent of patients survive this operation. *Why it fails:* Equivalent to a 10% mortality rate, yet patients and clinicians consent at different rates depending on which is stated. The clinical facts are unchanged. **In a pricing decision** > Pay by card and there's a 3% surcharge. *Why it fails:* Logically the same as a 3% cash discount, but the surcharge frame reads as a penalty and suppresses card use far more than the discount frame encourages cash. ## Practice ### Question 1 In the Asian disease problem, participants choose between a programme saving 200 of 600 people for certain, or a one-third chance of saving all 600. Most choose the certain option. When the same options are framed as 400 dying for certain versus a one-third chance nobody dies, most switch to the gamble. What does this show? A. Participants did not understand the probabilities B. Preference reversed with framing alone, since the options are mathematically identical — indicating risk aversion for gains and risk seeking for losses C. The second framing was more clearly worded D. Participants became more altruistic in the second condition **Answer: B.** Tversky and Kahneman's result is that the reversal occurs despite the outcomes being identical in every respect. The pattern it reveals is systematic: people tend toward risk aversion when outcomes are framed as gains and toward risk seeking when the same outcomes are framed as losses. This asymmetry is a foundation of prospect theory. ### Question 2 Which of these is NOT primarily a framing effect? A. "75% lean" versus "25% fat" on identical mince B. "Save £200" versus "avoid losing £200" for the same policy C. A study finding one drug outperformed another in a head-to-head trial D. "One in ten people experience side effects" versus "90% experience no side effects" **Answer: C.** Option C reports a substantive difference in outcomes — the drugs genuinely performed differently, so a preference between them tracks evidence rather than presentation. The other three present logically equivalent information two ways, which is the defining structure of a framing effect. ### Question 3 Why does the framing effect complicate the idea of neutral communication? A. Because communicators are usually dishonest B. Because every presentation requires choosing a frame, and there is no frame-free way to state the information — so the choice is which frame, not whether to use one C. Because audiences always misunderstand statistics D. Because neutral language does not exist in any context **Answer: B.** This is the genuinely awkward implication. Survival rate and mortality rate are both accurate; one must be chosen, or both given. The practical response in medicine and risk communication is to present both frames explicitly, which at least makes the equivalence visible rather than letting one frame operate unnoticed. ### Question 4 How does the framing effect relate to loss aversion? A. They are unrelated phenomena B. Loss aversion explains much of the framing effect: because losses weigh more heavily than equivalent gains, a loss frame produces stronger reactions than a gain frame C. Framing effects cause loss aversion D. Loss aversion applies only to money, framing only to health **Answer: B.** Loss aversion supplies the mechanism. If losses loom larger than equivalent gains, then describing an identical outcome as a loss makes it more aversive than describing it as a foregone gain. This is why surcharges deter more than discounts attract, despite being arithmetically the same. ### Question 5 What is the most practical defence against being framed? A. Ignore all percentages B. Deliberately restate the information in the opposite frame and check whether your preference changes C. Always choose the option described in terms of gains D. Trust your initial reaction, since it is less contaminated by deliberation **Answer: B.** Reframing tests directly for the effect: if "90% survive" and "10% die" produce different reactions in you, presentation is driving your judgement and you now know it. Option C is a rule that would leave you systematically manipulable by anyone choosing the frame. ## Frequently asked ### Is framing always manipulative? No. Some frame must be chosen for any communication, so framing is unavoidable rather than inherently deceptive. It becomes manipulative when a frame is selected specifically to produce a decision the audience would not make if shown the equivalent alternative — and when the alternative is deliberately withheld. ### How is framing different from anchoring? Anchoring involves a specific number pulling a numerical estimate toward it. Framing involves how equivalent information is described — as gain or loss, survival or mortality — shifting preference without any anchor value. Both are presentation effects, but they operate through different routes. ### Does the framing effect replicate reliably? Risky-choice framing of the Asian disease type is among the more reliably replicated effects in judgement research, though magnitude varies with domain, stakes, and population. Some specific framing paradigms have weaker records, so the general phenomenon is solid while individual reported effect sizes deserve caution. ## Related - [Anchoring Bias](https://www.criticalthinkingexercise.org/pages/glossary/anchoring-bias.md) - [Sunk Cost Fallacy](https://www.criticalthinkingexercise.org/pages/glossary/sunk-cost-fallacy.md) - [Motivated Reasoning](https://www.criticalthinkingexercise.org/pages/glossary/motivated-reasoning.md) - [Biases in Decision Making](https://www.criticalthinkingexercise.org/pages/exercises/biases-in-decisions.md) - [Understanding Statistics](https://www.criticalthinkingexercise.org/pages/exercises/understanding-statistics.md) - [Lesson: traps-and-pitfalls/cognitive-biases-decision-social](https://www.criticalthinkingexercise.org/pages/learn/traps-and-pitfalls/cognitive-biases-decision-social.md) ## Sources - [The Framing of Decisions and the Psychology of Choice (Tversky & Kahneman, 1981)](https://doi.org/10.1126/science.7455683) — Science ## Sitemap See the full [sitemap](https://www.criticalthinkingexercise.org/sitemap.md) for all pages.
