Except that according to the Gell-Mann Amnesia Effect the spell is never broken for most people. They turn the page and resume reading as if the source was still trust worthy.

The rest think they can winnow grains from chaff due to:

Dunning-Kruger effect, in psychology, a cognitive bias whereby people with limited knowledge or competence in a given intellectual or social domain greatly overestimate their own knowledge or competence in that domain relative to objective criteria or to the performance of their peers or of people in general.

I'd argue that for most people that's still the case.

It's easy to pontificate for a few hours, days, weeks even, and much harder many years and decades down the line for someone else to objectively evaluate the way you access media and say: "J decided to give up on X media after discovering the 'spell' and even decades later they stuck to their decision".

My money's on most people giving up these "major" decisions due to practical reasons or sheer boredom, somewhere down the line.

You could say that we almost want or need the lies.

it's great to have a name for this.
