You see this in medicine with meta analysis. The idea is that many studies increase the population studied and therefore will be more accurate. However if studies are poorly designed and/or by biased/compromised researchers the results are skewed to the bias. This of house happens all the time with controversial and political topics.
I think the best thing to do is ask multiple AI sources , the look at sources and ask same questions that excludes those sources. I haven’t seen AI do much in excluding unreliable biased sources.
Excellent point.
