Behavioral Economics

People choose what default and friction make easy, not what a neat lecture said they should pick.

Key Concept

• People do not act on facts alone - defaults and friction steer choices more than lectures.
• Level 1: Like when the cookie jar sits on the counter - you grab cookies because they are right there, not because someone lectured you.
• Level 2: A cafeteria puts fruit at eye level and hides candy behind glass - most people pick what is easy, not what they were told.
• Level 3: Behavioral economics explains why defaults and friction steer choices more than facts - a well-designed path beats a well-argued lecture almost every time.
• Level 4: Put the good option at eye level before you write the policy email - change the default, then argue less.
• Level 5: Mental Models gives lenses; this field explains why opt-in save beats bonus email campaigns - design the path, not just the message.
• Mental Models gives lenses; this field names why nudges beat sermons.
• A well-designed default beats a well-argued lecture almost every time.

Examples

• The cafeteria put fruit at eye level and salad sales jumped - no sermon required.
• Default opt-in to save made more people enroll than the bonus email campaign.
