[Movie] This Famous Medieval Book May Be a Hoax

[Koen G]

I once heard a definition of expertise that includes something along the following lines: the ability to communicate about the consensus on a topic. In other words, you can not only present research, but also frame it within its field. You can compare it to the consensus (if there is any) or weigh how successfully it challenges a competing view.

This video is certainly well researched, but it is presented in a formulaic clickbaity way. The fact that it shows one side of an ongoing debate as a recent scientific breakthrough clearly shows the value of expertise as well.
