Probably most people have heard of audience capture, but if you haven't, or even if you have, this is the best article I've seen to illustrate how the dynamics play out in the modern environment.
Audience capture has been a thing for at least 2500 years (thinking back to Greek and Roman orators / statesmen who turn into monsters once the crowd had locked them into the feedback loop) but I think the dynamics of right now are an order of magnitude worse and more consequential. The feedback is faster, the incentives are higher, the reach is wider, it operates 24/7/365.
I bet we'll have a whole new laboratory to watch this unfold, in real time, as a result of Hamas attacks.
