How Fear of the Bill Wrecks a Simple AC Repair
from The Human Diagnostic
I had a customer about two years ago who could not let me find anything wrong with his house. Not because the house was perfect. The house was middle-aged, normal, had its share of issues. He had called me out for what he thought was a refrigerant leak. I checked the system, found a small leak in the line set where it had been hit by a weed trimmer some years earlier, and started telling him what the repair would involve. Before I could finish, he started explaining why it could not be a leak from the line set. He said the line set was protected. He said the weed trimmer guy had been told to stay away from it. He said it must be the indoor coil. I said, sir, with respect, I have it on the leak detector right now. The reading is at the line set. He said, then your detector is wrong. This is a different episode from the customer in ep69 who could not commit to a decision because he was afraid the decision might be wrong. That customer was paralyzed by anticipated regret. The customer I am describing today is something different. He had no trouble making decisions. What he could not do was let anything in his life be a problem he had not anticipated. I want to talk about this today because the difference between these two patterns matters, and I have been thinking about it since. The relevant research here is Carol Dweck's work, summarized in her 2006 book Mindset. Dweck spent decades studying how people respond to evidence of their own failure or limitation. She identified two broad orientations. A growth mindset, in which the person treats failure as information about a process that can be revised. And a fixed mindset, in which the person treats failure as evidence about who they are at a permanent level. Core line: "There are situations where the truth has to be stated and accepted, where people have to take responsibility, where saving face would be a moral evasion."
