Yeah, it's a pretty obvious tell that people haven't worked in any depth with large amounts of complex data when they are surprised that there are huge anomalies. Many, many assumptions do not hold at scale. My mom's birth county's records building burned down in the 1940s. She has no birth certificate. When government agencies hear this, they ask if there are baptism records. The records from the church where she was baptized burned in the 1950s. It's been a massive pain for her, and government data systems are exposed to cases like this. Data at sufficient scale is incredibly messy because many seemingly impossible things have a reasonable probability of being present.
