To say 0 of this happened would definitely be untrue but I would say that coming from a time of sadistic landlord/warlord rule and the Aristocracy before that who could and would torture and murder you and possibly your family if your reports displeased them was a larger contributing factor as habits and traditions built up around saving you from this fate would be incredibly hard to shake in such a short time. A beaten dog in a new loving home still flinches at sudden movements. But also if you think of the wider culture such necessity would foster, of reporting accurate information being entirely secondary to pleasing the one being reported (generally at threat of terrible painful torture and or death). This culture of pleasing the one being reported to being more important than the actual information feeds back into both points anyway.
