The effect is definitely real - it happened to me many times, when I trust journalists in topics in which I have no expertise, sometimes much more than I should have, to my eventual regret. All while knowing to be extremely careful trusting anything in the press - especially non-specialized press - in my area of expertise, since the coverage is so universally bad that it's a cause for celebration when at least something correct and non-distorted comes through. I know that, and then kinda forget that, because questioning literally everything is kinda exhausting.

I am not sure what you mean by counter-example to the effect - I do not think the idea is that it's always happens. It's just the name and description of the thing that sometimes happens.
