The Furnace Repair She Remembered Wrong On Purpose
from The Human Diagnostic
A woman called me a year after a job to thank me for a furnace repair I barely remembered. It had been a long one. Her furnace quit on the coldest week of the winter, and I was at her house most of the day, pulling the blower, driving back to the shop for a part, coming back. By any honest accounting it was a hard, drawn-out afternoon. But that is not how she remembered it. She told me it was the best service experience she had ever had, and the thing she kept coming back to was the very end, when I sat down at her kitchen table, drew her a little diagram of what had failed, and told her the furnace had a good ten years left. There is a name for what she did to that memory. In the early 1990s, Daniel Kahneman, Donald Redelmeier, and Barbara Fredrickson found that people do not remember an experience by averaging all its minutes. They remember it by two moments, the most intense one and the last one. The long middle barely counts. Kahneman called that duration neglect. The low point of her day was in the middle, when I told her I had to drive back to the shop. If you had stopped her right then, she would have called it a disaster. But the day did not end there. It ended with me unhurried at her table, no pressure, telling her the news was good. The end is what the memory kept. I did not know the science back then. I sat down because forty-seven years has taught me that the last few minutes of a call are the minutes the customer keeps. I watch young techs do beautiful work for three hours and then pack up in a rush while the customer is still standing there with a question on her face. They get it backwards. The end of a call is not cleanup. It is the part that writes the memory. So on a hard call, when the day has been long and I am worn down too, I have learned not to limp across the finish line. I finish on purpose. Calm voice, clear explanation, a real goodbye. That woman did not remember her furnace day wrong. She remembered it the way memory actually works. She kept the end, and the end was good. Core line: "The middle of the job is mine. The end of the job is theirs."
