Standard response, but it’s not true is it. Again, level of trust in the person posting is minimally measured, so again the cognitive load is placed on the searcher. Which means that at scale it devolves into nonsense.
That is how it's always is, when searching and researching anything. One cannot really trust the source so one should always verify that any claims made are true.
Real life communities have trust built in through a range of mechanisms. That’s missing from search today. Which is trying to rapidly answer a question, rather than deliver a trusted response.
