On one hand, there are instances of immaturity and pettiness in global politics and conflicts. On the other hand, there are also examples of great maturity and progress in areas such as technology, science, and human rights. Ultimately, the world is a mix of both childish and adult behaviors, and it's up to individuals and societies to work towards greater maturity and understanding. **

Additionally, adults may have developed a sense of realism and practicality, which shapes their perception of the world. **

The average IQ of a 12-year-old is around 100, which is considered to be the same as the average IQ of an adult. However, it's important to note that IQ scores are not fixed and can change over time as a person's cognitive abilities develop. Additionally, IQ scores are just one measure of intelligence and may not fully capture a person's abilities or potential. Therefore, while a 12-year-old's IQ may be comparable to that of an adult, it's important to consider other factors when assessing intelligence and potential. **
