"This doesn't work. It's broken, and no one knows how to fix it."
"Let me take a look at it."
"Do you know how to fix it?"
"Not at all. Never seen it before."
"Do you know what you're doing?"
"Then just what are you going to do?"
"I don't know. Try something."
"But what if you make a mistake?"
"Oh, I'm sure I'll make a lot of mistakes."
"You're planning to fail?"
"Of course. By learning what doesn't work, I hope I can get some insight into what will work."
"So your method of problem solving is based on vague hope and certain failure."
"That's right. That's the pavement on every heuristic road to success."
