Defaults and Tired Decisions: Designing Your Own Choices
Many decisions are made for us by whatever option is pre-selected. Setting your own defaults on the days you feel clear-headed saves effort on the days you do not.
Some choices feel like choices. Many others are made by default: the plan that renews automatically, the box already ticked, the meal you always order. These quiet decisions add up to a large part of how we spend money and time.
The power of the pre-selected option
The default effect describes the tendency to accept whatever option is pre-set rather than choosing something else. Defaults work partly because changing them takes effort, and partly because a default can look like a recommendation. Organisations know this, which is why the most profitable option is often the one already selected.
Choice architecture
Choice architecture refers to the design of the ways in which choices are presented, and how that design influences decisions. The order of options, which one is highlighted, and how many there are all affect what people pick. You cannot redesign every website, but you can design your own environment.
Set your own defaults
- Savings. Arrange an automatic transfer to savings on payday, so saving happens before spending.
- Subscriptions. When signing up for a trial, set a reminder for the day before it renews.
- Meals. Keep a short list of easy, decent meals for tired evenings.
- Spending limits. Where a service lets you set deposit or spending limits, set them low; raising them should take deliberate effort.
Tired decisions
Many people notice that they make worse choices at the end of a long day. Researchers have proposed the idea of decision fatigue to explain this, although how strong the effect is remains debated. Whatever the mechanism, the practical lesson is sensible: make important decisions when you are rested, and do not leave big choices, such as large purchases or financial commitments, for late at night.
Fewer, better decisions
Routines are a way of making a decision once and reusing it. A standard breakfast or a fixed weekly shopping list is not a lack of imagination; it frees attention for choices that deserve it.
Review once in a while
Defaults can drift out of date. Every few months, look at what renews, what is automatic and what you choose out of habit, and ask whether it still fits.
