If you’re looking at an online course I agree the basics will be watched more often (as well as due to people not completing the course). But if you’re looking at something like cooking videos I’d expect the videos of people cooking cool things would get more views. People love food porn and want to watch something exciting about cooking but probably won’t watch a video about knife basics because it’s not as engaging to most people. That’s what I loved so much about Alton Brown and especially Good Eats, he makes so many mundane kitchen things exciting. Compare that to Thomas Keller’s Master Class, which is incredibly informative and I’d recommend it to anyone, but also significantly lower energy and you really have to want to learn the stuff to watch him julienne carrots for 5 minutes.
