Waiting

A wait feels shorter when it is filled with something that belongs to the service, when people know how long it will take and why, when the line is visibly fair and when they can see it moving. People remember a wait mainly by its worst and final moments, so a good ending matters, but shortening the wait itself remains the best fix.

What the report found

1. Fill the time. Occupied time feels shorter than empty time, but not every filler works. In hospital waiting rooms, how pleasant the room was shaped satisfaction more than the minutes waited, and a television did not make the wait feel shorter.
2. Remove the uncertainty. Unknown and unexplained waits feel longer than known ones. Telling people how long they would wait helped most in waits of middling length, and a promise about time raised satisfaction when it was kept and lowered it when it was broken.
3. Keep the line fair. People judge a queue by its order as much as its length. In two studies, people in a queue felt better, and were less likely to leave, as the line behind them grew.
4. Show progress and the work. In a dining hall experiment, letting customers and cooks see each other raised rated quality by about 17 per cent and cut preparation time by about 13 per cent. Progress bars that sped up near the end felt faster.
5. Design the end of the wait. People remember an experience largely by its worst and final moments. In a trial with 682 patients, adding a gentler end to an uncomfortable procedure made it remembered as less unpleasant.

Who it is for

For founders, service and operations teams, clinic and branch managers, app and product designers and anyone whose customers wait.

How we work

Field Guides turn the evidence into principles, each with the research, a worked example and what to try and watch out for. Every claim is graded, and where researchers disagree, as they do on whether telling people how long they will wait makes it better, both sides are set out before we say where we stand.
