Why would they? This person is claiming to be a metaexpert relaying what experts are saying. If somone doesn't have research skills or even know the structure of academia then they're probably very used to having to trust people. I'm wondering if they even have the skills to check anything if they wanted to: somone tried to support a bullshit etymology for an Arabic word by citing some pseudoscience website to me. That to them is just as credible as wiktionary or anything else.
