Ch7. The Framing Effect and Choice Architecture — Same Information, Different Decisions

Same Information, Different Conclusions

A surgeon describes an operation in two ways:

A: “This procedure has a 90% survival rate.” B: “This procedure has a 10% mortality rate.”

Mathematically, these statements are identical. Yet in research by Tversky and Kahneman, significantly more patients chose surgery when it was presented in survival terms than in mortality terms.

This is the Framing Effect. How an option is presented — its frame — influences the decision made.

The Root of Framing: Loss Aversion

The reason framing works is Loss Aversion, introduced in Chapter 1.

“10% mortality” is a loss frame — it highlights what could be lost. “90% survival” is a gain frame — it highlights what could be preserved.

Because losses feel roughly 2.25 times more powerful than equivalent gains, loss frames trigger a far stronger avoidance response.

Types of Framing

1. Loss vs. Gain Framing

Medical research (Meyerowitz & Chaiken, 1987):

Gain frame: “Performing breast self-examinations lets you detect cancer early and live longer.”
Loss frame: “Not performing breast self-examinations means you may miss early cancer detection and lose years of life.”

Result: The loss frame produced greater actual behavior change.

In public-health campaigns — energy conservation, smoking cessation, preventive screenings — loss frames are often more effective. However, an excessively threatening loss frame can provoke defensive avoidance instead of action.

2. Attribute Framing

“95% fat-free” vs “5% fat”

The meaning is identical, but the first sounds far healthier.

“70% success rate” vs “30% failure rate” — consumers trust the first more.

This is one of the most widely used framing techniques in marketing.

3. Goal Framing

How a message defines the goal creates different motivations.

“Exercise for a healthy life.” (achieve a positive outcome) “Exercise before you lose your health.” (prevent a negative outcome)

Research results vary on which is more effective, but for people with strong loss aversion the second formulation tends to produce stronger motivation.

Choice Architecture

In Nudge, Thaler and Sunstein introduce Choice Architecture — the practice of designing not the outcomes of choices, but the way choices are presented.

The Power of Defaults (Default Effect)

Combined with status quo bias (Chapter 1), defaults have a striking impact.

Organ donation comparison (Eric Johnson & Daniel Goldstein, 2003):

Germany (opt-in: must sign up): donation rate 12%
Austria (opt-out: must refuse): donation rate 99.98%

The underlying policy is the same; only the default differs. Yet the outcome gap is 99% vs. 12%.

Automatic 401(k) enrollment: When employers switched to automatic enrollment as the default, participation rates rose dramatically. The Save More Tomorrow program increased participation from 3.5% to 91.6%.

Compromise Effect and Decoy Effect

Compromise Effect: When three options are available, people tend to favor the middle option over the two extremes.

With wines priced at $10,$ 15, and $20, the$ 15 bottle sells most. Add a $30 bottle, and$ 20 sales increase — because $20 is now the “middle” choice.

Decoy Effect: Adding an inferior option makes a specific target option appear more attractive by comparison.

Framing and Financial Decision-Making

Narrow Framing

Investors tend to evaluate individual assets in isolation rather than within the context of their overall portfolio.

A single stock drops 5% → loss frame → sharp psychological pain. The same drop equals only a 0.2% decline in the total portfolio → far less pain.

Narrow framing intensifies the more frequently investors check their portfolios, increasing poor decisions driven by loss aversion.

How to Choose a Better Frame

1. Examine the Problem Through Multiple Frames

Before important decisions, deliberately consider several perspectives:

Gain frame: “What do I gain by choosing this?”
Loss frame: “What do I lose by not choosing this?”
Long-term frame: “How will I view this decision in five years?“

2. Convert to Absolute Values

“20% off” versus “Save $40.” Absolute figures support more accurate judgment than relative expressions.

3. Identify the Default

Always ask: “If I make no active choice, what default applies?” Defaults are not neutral — someone designed them.

Chapter Summary

Concept	Description	Real-life Example
Framing Effect	Presentation format influences decisions	90% survival vs. 10% mortality
Loss vs. Gain Frame	Losses feel more powerful than gains	Health campaign messaging
Default Effect	The preset option shapes behavior	Organ donation: 99% vs. 12%
Compromise Effect	Preference for the middle option	Wine list pricing strategy
Decoy Effect	An inferior option boosts a target option	Subscription plan design

Decision Defense Strategies:

View problems through multiple frames
Convert relative values to absolute values
Always check the default (“Who designed this?”)
Escape narrow framing — evaluate within the full context

From prospect theory to framing, we have seen how profoundly context and presentation shape our decisions. The next chapter explores how other people’s behavior pulls at our own choices — the power of social proof and social norms.
