Hot take: Humans have always been bad at this (in the aggregate, without training). Only a certain percentage of the population took the time to investigate.

For most throughout history, whatever is presented to you that you believe is the right answer. AI just brings them source information faster so what you're seeing is mostly just the usual behavior, but faster. Before AI people would not have bothered to try and figure out an answer to some of these questions. It would've been too much work.
