How do pseudostupidity imaginary audience personal fable demonstrate formal operational thinking?

Formal operational stage is the ability to consider multiple answers to the same question. Pseudo-stupidity is when a question is approached from a far too complex level, causing the individual to view the situation as, for example, a trick multiple choice question. With multiple answers to be considered, the individual may freeze up, and appear uneducated or slow, what they are actually doing is over-analyzing the situation, searching for nuances that are probably not to be found.

In the formal operational stage the adolescent develops this ability of introspection, or thinking about ones thoughts, this may cause the adolescent to become egocentric. Egocentric adolescents have a higher likelihood of developing the imaginary audience and personal fable.
