Defaults That Respect Autonomy
Offer sensible starting points—like modest round-ups and weekly top-ups—then clearly show how to change them. People who feel ownership rarely abandon. Provide simulations that reveal alternative paths without pressure. Small, reversible commitments lower the barrier to action, creating early wins that build confidence. Over time, many voluntarily increase contributions because progress is visible, interruptions are safe, and the journey feels chosen rather than imposed by an opaque, unchangeable configuration screen.
