Wendy Wood

"The USC psychologist who mapped how habits actually form"

Wendy Wood is Provost Professor Emerita of Psychology and Business at the University of Southern California. UK-born, she previously taught at Texas A&M and Duke and served as vice dean of social sciences at USC Dornsife. For more than thirty years her labs have measured how habits form as context-response memories — including the experience-sampling work behind the finding that about 43% of daily behavior is habitual, and cinema-popcorn experiments showing a strong habit can overpower taste. Good Habits, Bad Habits is her public translation of that research.

Key Ideas & Recurring Themes

Habits are context memories

About 43% of daily behavior is cued by place, time, and objects — not by a fresh decision. Design the room, not a sterner personality.

Friction beats willpower

Remove steps from the action you want and add steps to the action you do not. Self-control is often situation selection.

Reward must be immediate

The automatic self learns from payoffs that arrive now. Delayed virtue does not train the habit memory.

Notable Quotes

"We spend a shocking 43 percent of our day doing things without thinking about them."
— Good Habits, Bad Habits
