I hear this a lot - but are people really watching longform political YouTube videos and passively letting the algorithm choose their next video for extended periods of time? I very rarely watch a political video on YouTube but when I do it's usually linked from a site like Reddit, and then I'm very unlikely to watch the next video in the queue after it finishes. If the algorithm actually does suggest more and more radical videos I wonder if it's a case of reverse causation - the algorithm suggests a more radical video because it learns what people actually want to do and choose to do, which is watch the most outrageous and/or bloodcurdling video out of the options presented to them?
