Mine was the second comment and you had not responded to the first comment when I made my post. As Crzy demonstrates it was not an obvious error. Anti-intellectualism is quite common in the U.S.
Joost Meerloo, in The Rape of the Mind, noted that the ones most susceptible to some methods of interrogation or propaganda were often those trained to withstand it.
Perhaps it's a false sense of security, or the dunning-kruger effect.
That isn’t quite what Dunning-Kruger is about. People with less competence tend to overestimate their abilities more than people with higher competence. For example, a person with ability 3 out of 10 might say their skill is a 5 whilst a person with ability 9 out of 10 might say their skill is a 10.
Where was the overestimation of one’s abilities in the comment made by Crzy?
The alleged fact that people trained to resist propaganda are more susceptible to it is only an instance of Dunning-Kruger if said people overestimate their abilities in this area greater than people with a higher ability to resist propaganda. That wasn’t established.
To observe this phenomenon, Dunning and Kruger gave students tests of grammar, logical reasoning, and humor. The psychologists found that those who scored in the bottom 25% tended to overestimate their ability and test score. Most predicted their scores to be above the 60th percentile.
On the other hand, those who overperformed -- those in the top 25% of the students -- also incorrectly assessed their final result. Most of these students estimated their scores to be in the 70th- to 75th-percentile range. But most actually scored above the 87th percentile. While this is also not a realistic self-assessment, the researchers found that this group was competent enough to understand how they got a higher score, unlike the low performers. In other words, the gap between perceived and actual performance is smaller.
