# nudge (drift-steer)

Power that sets no wall but pushes where drift goes inside another's window, so its choices go one way without its model holding the push.

## Emergence
**Emerges from:** [power](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-power.over), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [set](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-set.fix), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [push](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-push.action), [choice](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-choice.decision), [model](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-model.representation), [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [go](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-go.movement), [inside](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-inside.spatial), [way](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-way.method), [hold](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-hold.physical)

**Through:** Each option stays open, so no wall is set and the chooser's reach is untouched; what moves is which way the parameter drifts when nothing else decides it. Because the push is not in the chooser's model, the choice reads to it as its own.

**Novel properties:**
- power with no wall in it
- reach left whole while its use is steered
- a push that reads as one's own choice

## Examples
- Madrian and Shea (2001) found that when a US employer made 401(k) enrollment the default, far more new employees stayed enrolled than had opted in under the old rules. *(economics)*
