If you were concerned about someone's character then you need to ask questions which really help you to understand who the person is – not questions which are easy to game by lying.
I'd argue asking something like someone's opinion on veganism is a better question because it might help you understand how the person thinks about the types of harms Anthropic are concerned about without being such an easy thing to lie about.
Obviously they could say "yeah, I think veganism is good", but someone who actually inhabited that view or was just conflicted about balancing meat consumption and the suffering of animals would probably answer with a lot more nuance that helps you understand how that person thinks about similar kinds of ethical concerns.
