As far as I can see from observing my normie wife. The doctors on MSM must have been "fact checked" somehow and are much more credible than a dissident specialist like for example Professor Dolores Cahill by virtue of being on the MSM

She would believe an MSM presented doctor with an unchallenged soundbite in an instant. She discarded a detailed video by Professor Dolores Cahill. on the basis that there are always some dissident specialists with a different opinion. They aren't worth listening to because they are dissident.

Possibly her intuition is that if something were important and and true, the MSM would tell her about it.

No thinking involved.
