Lock in the future-oriented choice before the temptation arrives
Pre-commit when motivated and calm so a future impulsive self doesn’t undo it.
Why it works
Pre-commitment works by binding future behavior at a moment when long-term preferences are active and the present-biased self is relatively quiet. The pre-committed constraint is then self-enforcing: to break it requires deliberate effort at a second decision point, which creates friction and a cooling-off window. This is the behavioral economics equivalent of Odysseus tying himself to the mast.
How to do it
- Set up automatic transfers to savings or investments the day you receive income — before the money hits your checking account.
- Raise savings rate after a raise or bonus before the new income level becomes the new normal.
- Use account structures (locked savings, limited access) that add a deliberate barrier to withdrawing.
Evidence
Save More Tomorrow (SMarT) program research showed that pre-committing to future savings rate increases led to substantial long-run savings growth without feeling like a sacrifice, because future income rather than current income is committed. (rct)
The SMarT study was conducted in workplace 401(k) contexts; direct replication in other savings vehicles is less studied, though the pre-commitment principle is broadly supported.

Common mistake
Planning to save "whatever is left over" at the end of the month — which reliably leaves nothing, because the present self spends whatever is accessible before the plan can activate.

More practices for The Marshmallow Test and Your Money
- Name your present bias before you buy
Recognize that your brain systematically overvalues right now — naming it weakens its grip.
- Cool the purchase by abstracting it
See the item in "cool," abstract terms to drain the craving before it drives a decision.
- Make the future self vivid and concrete
A vivid, detailed image of your future self competes more effectively with the present temptation.
- Use the pain of paying to slow down spending
Paying in cash (or seeing the real number) activates loss aversion and reduces mindless spending.
- Translate price into hours of work or future value
Convert a price into concrete terms — work-hours or compound-growth — to make the real cost visible.
- Apply a 24-hour (or 72-hour) rule to non-essential purchases
Wait a fixed period before completing any unplanned purchase above a set threshold.
