🧠 What's Actually Happening?
The affect heuristic is a mental shortcut in which people make judgments and decisions based on their current emotions rather than through deliberate, analytical reasoning. Identified by Paul Slovic, it means that if we feel positively about something, we judge its risks as low and its benefits as high — and vice versa. Emotions serve as a rapid, automatic evaluation system.
Here's the sneaky part: Emotional responses occur faster than analytical thinking and served as rapid survival signals throughout evolution. The brain uses current feelings as information ('How do I feel about this?'), creating an inverse relationship between perceived risk and perceived benefit.

IRL: The affect heuristic drives public policy debates: people who love a technology see only benefits; those who fear it see only risks. Marketing exploits this by creating positive emotional associations with products through branding and advertising.
🔍 How to Spot It
Separate emotional reactions from analytical assessment. Use structured decision frameworks that require explicit evaluation of risks and benefits independently. Take time between emotional reaction and decision. Seek data-driven perspectives.
