People will call a visit fine and then not come back, and they will not point at the long middle that made them say fine. They keep one bad moment and the way it ended. The rest is a blur. A workshop that averages the blur will congratulate you for a number the customer is not using.
Daniel Kahneman, Barbara L. Fredrickson, Charles A. Schreiber and Donald A. Redelmeier reported the trials in When More Pain Is Preferred to Less, Psychological Science, November 1993. In the short trial a person held a hand in water at 14 degrees Celsius for 60 seconds. In the long trial the other hand stayed at that temperature for 60 seconds, then for 30 seconds more while the water was raised to 15 degrees. Still painful, and for most people distinctly less so at the end. Asked later which trial to repeat, 22 of 32 chose the longer one.
What the memory keeps
The authors' reading is that duration played a small part in how the episode was judged afterwards. The worst moment and the final moment dominated. For a typical person the worst of the short trial and the worst of the long trial were about equally bad, and the ending of the long trial was better, so the memory of the long trial won. It was still unpleasant at the end. The kindness was relative. Eleven of the 32 showed little or no easing, and two reported more discomfort as the water warmed. For those people the long trial was not the kinder memory, and the pattern predicts they would not prefer it. The result is not a magic trick that works on every participant. It is a description of whose memory moved.
Most people could say which trial had lasted longer. They did not use that knowledge when they chose. The authors call this a mistake: more pain, chosen because the memory of it was less awful. They do not claim duration never matters. An episode much longer or much shorter than people expected may bring duration back. A trend can matter, and sometimes the start dominates. They are arguing that people stand in for a whole episode with a few moments, not that two moments are a law.
What the agenda gives away
This was a cold water bench, not a service counter. When someone chooses which experience to repeat, which moments are doing the choosing, and did anyone in the room look at those moments rather than at the average of the whole visit. A workshop that leaves with a single satisfaction figure, and no sentence for the worst point or the ending, has measured the blur.
Be suspicious of a day whose only move is to shorten the visit. If the experience is already about as long as people expect, the paper suggests they may neglect that length and still judge you on the worst moment and the close. If the visit is wildly off what they expected, duration can return, and a cut may be the right work. Say which of those you are in before you propose a fix. Decorating the last minute, while the worst moment stays, is the cheap version of a problem the authors raise in medicine: a kinder tail so the memory improves, without touching the pain. The day has to be allowed to change the worst moment, not only the exit.
Collective Campus is building high-performance culture and teams for the AI world. The customer experience workshop is for a team that can name one live experience, its worst moment and its ending, and is allowed to change one of those rather than average them away. What to measure before you book is in the measure that has to exist first. What the session should leave fixed is in what the workshop should fix. What belongs on the agenda before you pay is in the agenda before you pay.
What to bring
Bring one experience a real customer finishes, the worst moment in it, and the way it ends. If you cannot name those two, the day will smooth a score and leave the memory where it was.
