Image description: A Duolingo screen asks the learner to pick a streak goal after starting a new streak, using a preselected default to keep the flow easy.

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.

## 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.
