There is an explicit culture and mechanism of blamelessness around safety concerns and minor violations/deviations, which is incredibly helpful. Read about the ASRS* program (admin'd by NASA, with anonymity for non-intentional issues, prohibition on use of submissions for enforcement purposes, and explicit "get out punishment" card from the FAA): https://asrs.arc.nasa.gov/overview/immunity.html

The FAA is also explicitly including "evidence of voluntary compliance" and "just culture" in its approach to aviation safety, and explicitly changed its goal from enforcement and proof to ensuring compliance [with enforcement being only one available tool]: https://www.faa.gov/about/initiatives/cp (PDF pres: https://www.faa.gov/sites/faa.gov/files/2022-09/The%20Compli... )

I'd also read a bunch of aviation reports: https://www.ntsb.gov/Pages/monthly.aspx (more detailed reports are available approximately 2 years after the occurrence date and more details are available for fatal or air carrier occurrences, so if you don't care which ones to read, filter for those to start).

If you're more video oriented, watch @blancolirio, @NTSBgov, @AirSafetyInstitute, or @pilot-debrief. (I'd skip @ProbableCause-DanGryder.)

For a short summary, there is an intense focus on determining the facts (who, what, when, where, maybe some guesses as to why) and drawing conclusions about primary and contributing causes from there.
