It's generally pretty easy to spot the fakes if you have a basic understanding of the field and are just researching for specific details. Frankly, for the stuff I typically look for, there are surprisingly few fakes to be found. This may change with YT deprecating the down-vote arrow.

I would say critical thinking, learning to distinguish good information from bad is a valuable life skill that is only getting more valuable with time. Something we should try to teach people about from a young age.
