That Wikipedia article is impressively terrible. It cites an opinion column that couldn't spell Sokal correctly, a right-wing culture-war rag (The Critic) and a screed by an investment manager complaining that John Oliver treated him unfairly on Last Week Tonight. It says that the "Gell-Mann amnesia effect is similar to Erwin Knoll's law of media accuracy" from 1982, which as I understand it violates Wikipedia's policy.
By Crichton's logic, we get to ignore Wikipedia now!
Even setting aside the fact that Crichton coined the term in a climate-science-denial screed — which, frankly, we probably shouldn't set aside — yeah, it's just not good media literacy. A newspaper might run a superficial item about pure mathematics (on the occasion of the Abel Prize, say) and still do in-depth reporting about the US Supreme Court, for example. The causes that contribute to poor reporting will vary from subject to subject.
Remember the time a reporter called out Crichton for his shitty politics and Crichton wrote him into his next novel as a child rapist with a tiny penis? Pepperidge Farm remembers.
