They have. It's called "peer review". It is just that peer review is a slow process, so it doesn't really work in a fast-moving crisis environment.

Part of peer review being a slow process may be fixable (although it is difficult to compel unpaid, volunteering reviewers to adhere to strict deadlines), but part of peer review being a slow process is specifically that if you do not want to rely on heuristics such as author credentials you need to take the time to really analyze a paper to avoid falling into the traps mentioned in the original article (confirmation bias, being misled by an authoritative tone etc.). And HN/Reddit votes IMHO are definitely not a good example of avoiding any of these.
