Most teenagers, especially those who graduate from high school with a standard diploma, are at the level of thinking that jean piaget identified as

Formal Operational thinking.

Explanation:

Jean Piaget, a psychologist, developed cognitive development theory which described that as children grow their thinking skills improve and they start thinking more abstractly. In this theory he described that there are four stages of cognitive development in a child:  "Sensorimotor Intelligence", "Preoperational Thinking", "Concrete Operational" and "Formal Operational Thinking".

Sensorimotor Intelligence and Preoperational Thinking develops during the early years of the child starting from birth to around 7 years of age. Then, concrete thinking starts from 7-8 years to 12-13 years of age. According to Jean Piaget, formal operations stage of thinking begins around 11 when the child is able to manipulate things around him and even think more theoretically. This thinking develops over the teenage. Thus, answer is Formal Operational thinking (according to age of children in high school with standard diploma).

hope this !

glass wants to live in a world of super heroes and villains. he have lived all his life trying to be responsible for the creating the origin story of a super hero; he schemed and caused many incidents (many of them fatal) hoping that someday someone with superpowers would show up and save the day.

he knew himself very much. he saw himself as a villain of a real-life super hero story. he was aware of his strengths (more than smart enough for being manipulative and scheming) and weaknesses (having fragile bones and having to rely on his mind to succeed).
