Endowed Progress Effect
People who are given artificial advancement toward a goal are more likely to persist and complete it than people starting from zero.
Also known as: Endowed Progress, Artificial Advancement Effect, Head Start Effect

Explanation
The Endowed Progress Effect describes how giving people a head start toward a goal, even an artificial one, increases their commitment and the likelihood that they finish. It was demonstrated by Joseph Nunes and Xavier Drèze in 2006.
## The Original Study
Customers at a car wash received loyalty cards. One group got a card that needed 8 stamps for a free wash. Another group got a card that needed 10 stamps but came with 2 already stamped. Both groups needed exactly 8 purchases. Yet 34% of the 'head start' group completed their card, against 19% of the other group, and they completed it faster.
## Why It Works
- **Reframing the task as already started**: A task in progress feels like something to finish, not something to begin. This activates the same pull to complete that drives the Ovsiankina Effect.
- **Goal gradient**: Feeling closer to the goal increases effort, as described by the Goal Gradient Effect.
- **Reduced starting friction**: Getting started is usually the hardest step. Endowed progress removes part of it.
The effect is strongest when the endowed progress is framed as progress toward the goal, not as a free gift. Simply saying 'here are 2 bonus stamps' without making them count toward completion weakens it.
## Applications
- **Product design**: Profile completeness bars that start at 20%, or onboarding checklists with the first step already checked.
- **Loyalty programs**: Pre-stamped cards and starter points.
- **Personal productivity**: Start a new project by doing a trivial first step right away (create the note, write the title, outline three bullets) so that you return to something already in progress rather than a blank page.
- **Habits**: Count what you have already done toward a new habit to create momentum.
## Caveats
Manipulative uses can backfire once people notice them. And endowed progress only helps when the goal itself is worth pursuing.
