Good points, FD and Evo. Unless you have an instructor interested in the subject (mine happened to be working for the RAF Flight Safety Directorate at Bentley Priory whilst teaching me) or read up on the subject yourself, you may complete a PPL with little study of human factors in accidents, decision making, accident event chains etc. The one thing that we are all looking to acquire is pilot judgment, but it is not a subject referred to much in the manuals. Attending and/or giving seminars is part of compulsory continuing education in many professions (including that of flying instructor). We are mostly hobby pilots, but I nonetheless think that our currency requirements might encourage attendance at seminars on accident analysis and prevention.
