Short answer: Duolingo added a streak-goal choice immediately after users started a new streak. The team did not store or use the chosen value, but the act of choosing created commitment; Ali reported that users retained better weeks after seeing it, and a later version with no preselected option produced stronger goal selection without causing drop-off.

## Visuals

### Primary visual: Duolingo streak-goal picker before and after a 14-day selection.

Image description: The composite shows an unselected picker with a disabled Continue button beside a selected 14-day goal with an enabled Continue button. It does not establish which state appeared first on entry.

Image description: The visible state has a selected 14-day goal and an enabled Continue button; the screenshot alone cannot establish whether the selection was a default or a user action.

### Visual: Duolingo unselected and selected streak-goal states.

## Evidence

The evidence is the before/after UI: a lightweight goal-selection screen became a commitment device even though the selected value was not operationally used.

## What changed

- Control: users saw a streak goal screen with a preselected option.
- Experiment: users had to actively choose a goal before moving on.
- The selected goal did not change the downstream app experience.

## Why it matters

- Positive friction can raise motivation when the user understands the goal and the effort feels meaningful.
- The commitment moment matters even when the product does not personalize based on the selected value.
