Framing Effect
Being influenced by how information is presented
What is it?
The framing effect demonstrates that logically equivalent information can lead to different decisions depending on how it's presented. This violates the economic assumption that rational agents should respond to substance, not presentation. Kahneman and Tversky's famous "Asian disease problem" showed that people choose risk-averse options when outcomes are framed as gains but risk-seeking options when framed as losses—even when the mathematical outcomes are identical. Framing operates through several mechanisms: positive vs. negative emphasis, absolute vs. relative numbers, narrow vs. broad context, and order effects. Marketers, politicians, and negotiators exploit framing constantly: "95% fat-free" versus "5% fat," "save $10" versus "avoid losing $10," "3 out of 4 dentists recommend" versus "1 in 4 dentists don't recommend." Medical decisions are particularly susceptible—patients make different treatment choices based on whether outcomes are presented as survival rates or mortality rates. Defense against framing requires actively reframing information in multiple ways, asking "how would my decision change if this were presented differently?", and focusing on absolute numbers and final states rather than relative changes or selective statistics.
Example
"90% success rate" sounds better than "10% failure rate." "Save $50" is more attractive than "Spend $200 instead of $250." "1 in 1000 risk" feels different than "0.1% chance."

How to Prevent It
How would I view this if it were framed differently?
What are the actual facts, independent of presentation?
Is this framed as a gain or loss, and does it matter?
Who framed this information and what are their incentives?
What's being left out of this presentation?
Reframe the information in multiple ways before deciding.
Focus on absolute numbers, not just percentages.
Request information in different formats (gains vs. losses).
Strip away emotional language and focus on raw data.
Present options yourself using neutral framing.
