Temptation Bundling
Pair present sacrifices with small immediate rewards to beat present bias
Humans are wired to discount the future. All the decisions that benefit future-you — saving money, exercising, eating well, practicing safe sex, wearing sunscreen — require foregoing something pleasurable right now. Economists call this present bias, and it is not a flaw so much as a deeply embedded feature of human cognition. The problem is that the payoff is remote while the cost is immediate.
Temptation Bundling is a strategy developed by behavioural scientist Katy Milkman to counteract present bias without requiring willpower alone. The principle is simple: couple the behaviour you need to sustain with a small reward you actually enjoy in the short term. This converts the sacrifice into a package deal — you get the fun thing and the boring necessary thing simultaneously or in sequence.
Angner describes his own implementation: he brings home-cooked lunches to work Monday through Thursday (the sacrifice), then allows himself a good restaurant lunch on Friday (the small indulgence). The Friday reward creates a short-term incentive that keeps him on track across the week. Milkman's original research suggests an even tighter version: listening to a compelling audiobook only while on the treadmill, so the enjoyable thing is literally gated by the healthy behaviour.
- Present bias is a hardwired feature of human psychology, not a character flaw to overcome through willpower.
- Attaching a small immediate reward to a difficult long-term behaviour creates a short-term incentive without requiring self-denial.
- The reward must be proportionate — large indulgences offset the gain and defeat the purpose.
- Gating the enjoyable thing on the behaviour (audiobook only on the treadmill) is more effective than sequential rewards.
- Social accountability functions as an additional short-term reward: approval from a peer group fires immediately, unlike future-self benefits.
- Name the behaviour you want to sustainBe specific: not 'exercise more' but 'bring my lunch to work Monday through Thursday.' The sacrifice must be clearly defined so you know what you're rewarding.
- Choose a proportionate indulgenceIdentify a small, genuinely enjoyable reward — not a trip to Bali, not a £500 purchase. Angner uses a Friday restaurant lunch or a £5-10 vintage tie. The reward must be small enough that it does not erase the financial or health benefit of the behaviour.Pro tipEven a very small reward works — a vintage tie for a few pounds, a favourite podcast episode, a coffee at a good café.WarningIf the indulgence is outsized relative to the sacrifice, temptation bundling becomes rationalised over-spending.
- Try simultaneous bundling where possibleKaty Milkman's strongest version: the enjoyable thing happens only during the difficult thing. Audiobook only on the treadmill. Good podcast only while doing dishes. This makes the enjoyable thing conditional on the behaviour.Pro tipPromise yourself not to listen to the audiobook unless you're actively on the treadmill — the anticipation of the cliffhanger becomes the motivator.
- Add social pressure as a parallel leverFind a peer group committed to the same behaviour. Short-term social approval — the 'streak' on an app, the check-in with friends — fires immediately and complements the delayed payoff of the core behaviour.Pro tipFitbit groups, saving circles, or even a simple text-thread accountability group all work. The approval is immediate even if the financial payoff is years away.
Angner brings home-made lunch to work Monday through Thursday. If he succeeds all four days, he allows himself to go out for a decent restaurant lunch on Friday — specifically not the cheap cafeteria he would default to.
Milkman's research suggests listening to a compelling audiobook only while on the treadmill. You gate access to the enjoyable content on performing the difficult behaviour. The desire to hear what happens next drives you back to the treadmill.
Angner's most minimal version: after a disciplined week, he allows himself to buy a vintage tie for £5-10. The cost is negligible, the climate impact near-zero, but the small novelty gives him something to look forward to.
The concept comes from Katy Milkman's behavioural science research (she wrote the book 'How to Change' on the topic). Angner cites her work directly and reports using temptation bundling in his own life. He frames it as the applied economic answer to present bias — the same phenomenon that makes people overspend, under-save, under-exercise, and overeat. His own self-description as 'a standard joke in my world — people who go into decision-making often do it because they know they're kind of bad at it' makes the framework more credible: even the expert needs scaffolding.
