Pilots have loads of checklists, many of them committed to memory. If there's a problem, there's a checklist for it and following the checklist should lead you to a solution or at least tell you what is wrong. The downside is that checklists can't account for every possible thing going wrong. A little piece of wire jamming a hydraulic system is going to be a hard fix. Even if you have the tools and access to the component, do you have time while the plane is nose down?
Planes have to be predictable, they can have massive failure states but the solution must be repeatable. Unknown failures, regardless of the severity, are a major problem and should always be tracked and investigated. A small unknown failure could be a symptom or precursor to a much larger problem.
Everyone hates paperwork but it's what saves lives.
