Do you mean that you wouldn’t trust any objective claims they made without verifying the claims yourself? Shouldn’t you not do that anyway, with anyone, including people with strange cosmological beliefs but also renowned experts?
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.
