I don’t know if I could really trust the opinions of a co-worker who believed the earth is flat. I’m pretty sure that would influence my attitude towards them in technical discussions as well.
Arguably, the differentiating factor between humans and animals is our ability to organize on large scales. Monkeys and killer whales can coordinate behavior in groups of sometimes up to 50 or maybe 100 individuals. However, humans can coordinate behavior across millions of people. Building a modern automobile, a computer chip, or the social security system requires coordination across so many individuals, no one person can fully and deeply understand the entire system.
The ability of humans to believe information that they do not fully know is true, is probably one of the defining traits of humanity.
