I don't entirely agree with what you've said in regards to a culture of Checklists used for every situation. I don't think there are any Flight Schools that would teach this and am pretty sure they teach memory items that need to be known off by heart designed to get the Aircraft under control which are then backed up with a checklist to confirm all steps have been taken properly. I'd dare say if there is a school that teaches that the very first action should be to take out a checklist they should be taken to task and would be interested to hear of any such out there.
