No, this sentiment is very wrong. 10% of the population is functionally illiterate. Another 10% can't do basic arithmetic. Another 10% has more important things to worry about than vetting all their sources. Another 10% just can't be bothered. There are many more reasons why expecting everyone to just be able to develop the ability to critically gather and evaluate information is clearly a fantasy that can only be entertained when you don't realize how incredibly challenged people are, probably because they don't interact with any.
