Well, going after low hanging fruit, people that think shoplifting is a major expense for most retail stores that would cause locations to shut down. Obviously self checkout and how it makes abuses and shoplifting easier shows that that is a much smaller cost than just the labor of paying a cashier. It is always advantageous for PR reasons to blame crime and shoplifting rather than a lack of profitability or demand for shutting down locations.
But on a more serious note, it is a lack of curiosity or unwillingness to challenge really simplified narratives about common facets of daily living. A more original answer might be the lack of ability to pick up on jokes or sarcasm. I was always shocked about some people's inability to pick up on sarcasm, even when the statements would make no sense or be obviously wrong, if they were done sincerely. There is an awareness of context and meta-awareness that is what I usually identify with intelligence, as opposed to expertise in a specific domain.
I've actually heard this in a more egregious form. I once heard someone claim that sarcasm is an anglosphere phenomenon and someone that isn't a native English speaker would never be able to understand sarcasm.
