I’m not sure that it makes sense, at our current level of knowledge of scrupulosity, to declare that anything is “the” cause of scrupulosity. I have no doubt that what you say is *a* cause of scrupulosity, but the term is deliberately quite broad. For example, clinical OCD can cause scrupulosity, but that’s not related to internalized “shoulds”, it’s related to the mind’s tendency to obsessively think about things it’s trying not to think about.
