Framing Effects

Same Information, Different Decisions

Rational decision theory assumes that how a choice is presented should not affect the decision made — what matters is the substance of the options, not their packaging. Framing effects demonstrate that this assumption is wrong. The way information is presented systematically changes the choices people make, even when the underlying facts are identical.

The definitive experimental demonstration came from Amos Tversky and Daniel Kahneman in a 1981 paper in Science, widely known for the "Asian disease problem." Participants were asked to choose between two programmes to address a disease expected to kill 600 people:

Gain frame: Programme A saves 200 people. Programme B has a one-third probability of saving 600 people and a two-thirds probability of saving nobody.

Loss frame: Programme A results in 400 deaths. Programme B has a one-third probability of nobody dying and a two-thirds probability of 600 deaths.

Mathematically, the two versions are identical: saving 200 from 600 is the same as 400 dying from 600. But in the gain frame, 72% chose Programme A (the certain option). In the loss frame, 78% chose Programme B (the risky option). The framing alone reversed the majority preference.

Why Framing Works: Prospect Theory

Framing effects arise directly from the asymmetric value function in Prospect Theory, which Kahneman and Tversky developed in their 1979 paper. The key insight is that gains and losses are evaluated relative to a reference point, and that losses loom larger than equivalent gains. When a choice is framed as avoiding a loss, people become risk-seeking. When framed as achieving a gain, they become risk-averse.

The reference point itself is set by the framing — and the framer controls the reference point.

Framing in Personal Finance

Framing effects are pervasive in financial products and communications:

Savings rate vs spending rate: "Save 20% of your income" and "spend 80% of your income" are mathematically identical, but the savings frame tends to motivate more saving behaviour, because it activates a positive goal rather than a loss.

Fees expressed as percentages vs pounds: A "1.5% annual management fee" and "£1,500 per year on a £100,000 portfolio" describe the same cost. Research consistently shows people respond more strongly to the absolute number — but fund providers prefer the percentage frame.

Headline vs fine print: Mortgages marketed as "only £1,200 per month" are framed to activate the manageable-payment comparison; the total cost over 25 years (often three to four times the purchase price) is structurally de-emphasised.

Attribute Framing and Goal Framing

Researchers Irwin Levin, Sandra Schneider, and Gary Gaeth published a comprehensive review of framing effects in 1998, identifying three distinct types. Attribute framing (the same attribute described positively or negatively — "95% fat free" vs "5% fat") affects evaluations of objects. Goal framing (emphasising gains from acting vs losses from not acting) affects motivation. Risky choice framing (Tversky and Kahneman's original work) affects risk preferences directly.

All three operate in financial marketing, product design, and negotiation.

Quiz me on this
What did Tversky and Kahneman's Asian disease problem demonstrate?
  1. That people are systematically irrational when lives are at stake
  2. ✓ That mathematically identical choices can produce reversed majority preferences depending solely on whether they are framed in terms of gains or losses
  3. That cultural background determines risk tolerance
  4. That probability estimates are poorly understood by most people
According to Prospect Theory, why does framing in terms of losses make people more risk-seeking?
  1. Losses are more difficult to calculate accurately, leading to imprecise risk assessment
  2. ✓ Losses activate a risk-seeking response because people will gamble to avoid a certain loss, while they accept certain gains readily
  3. People with prior financial losses have generally lower risk tolerance
  4. The loss frame provides less information, leading to random choice
Why is presenting an investment fee as a percentage rather than an absolute pound figure an example of framing?
  1. Percentages are more accurate than absolute figures for comparing fees across portfolios of different sizes
  2. Regulations require fees to be expressed as percentages
  3. ✓ The percentage presentation exploits the tendency for smaller numbers to feel less significant, even when they represent identical costs
  4. Absolute figures are harder to calculate from percentage-based fee structures
What is the key practical implication of attribute framing (e.g. "95% fat-free" vs "5% fat")?
  1. Negative framing is always more persuasive than positive framing
  2. ✓ The same attribute described positively or negatively can significantly affect how an object is evaluated, even when the information is identical
  3. Attribute framing only affects food purchasing decisions, not financial ones
  4. Consumers who notice the framing are immune to its effects
