IQ >= 120 is a fairly low bar. IQ is also a strong indicator for the potential for someone's behavior to be influenced by delusions (rather than near mode thinking + social pressure being the dominant adaptation.)
Do you mean do say that people of ordinary intelligence, as a general rule, don't actually believe whatever it is they say they believe, but instead just parrot what those around them say? You might be right. I think I need to find a way to re-immerse myself in a crowd of people of average intelligence; it's been far too long, and my predictive/descriptive powers for such people are fraying.
Note that none of this is sarcasm; this comment is entirely sincere.
