What do you mean by people trying random things? I think that approach (if I understand the term correctly) is more or less what debugging is as a form of scientific investigation. If you observe a car mechanic trying to find the problem with a car, he would go like: "is this pin faulty? No. Is the combustion engine faulty? No. Are the pedals faulty? Yes." where the mechanic starts with some assumptions and disproves them by testing each of those assumptions until (hopefully) the mechanic finds the cause of the fault and is able to fix it. Similar types of investigations are important to how natural science is done. So it would be helpful if you can clarify your intended meaning a bit more. Maybe I or someone else would learn from it.
