Grocery shopping from a list on the fridge
Everyone can add to it, it is impossible to ignore, and it requires no unlocking. The fridge list wins on capture cost, which is the only metric that matters for a shared chore.
What matters here
- Zero friction to add an item
- Visible to everyone in the house
- No phone needed at the moment of noticing
- Only works while you are at home
- No memory of what you bought last week
Why it keeps working
Most systems fail at capture, not at organization. The fridge list has the lowest capture cost of anything in the house, so it collects everything. A system that collects nothing organizes nothing.
The shop-time gap
The list is complete at home and often forgotten at the shop. A photo before leaving solves the immediate problem, and a shared digital list solves it permanently for households where people split the shopping.
Keeping both
Paper at home for capture, a shared list for the shop. Adding something to the list is a task in itself, so keep them in sync when the paper fills up rather than continuously.
