Most YouTube channels are trying to make you think you are getting smarter because flattering your viewership's egos is a proven way to grow it. They work from a top-down perspective where they hold the information and you listen without questioning; much like a classroom; for people who mostly think "learning" is such process.
It is an entirely different experience to watch a YouTube channel where the host is actually working hard to make you think, even when this forces the host to be stern with its listeners, to correct their incorrect patterns of thinking when they call in, and to be available for any corrections by their viewers and willing to publicly correct an error.
For all that, I like Stefan Molyneux's podcasts on YouTube.
