  1. Hardly. After all, teenagers usually pass intelligence tests a little worse than themselves, but already adults (say, in 25-30 years). Such a thing as working memory seriously correlates with the level of intelligence: better RB – higher intelligence. This type of memory is subject to age-related changes, the peak is somewhere in 20-30 years. It also belittles the cognitive abilities of teenagers that their brains are still partially maturing (a stupid word, but it just came to mind right away). For example, small structural changes occur in the prefrontal cortex (for example, more stable connections are formed with the striatum and, possibly, other limbic structures), stable functional connections are established between other systems, for example, the default system and the executive control network. If it is very simplified, these networks work alternately in adults, but not quite yet in adolescents, which may lead to frequent mixing of cognitions and emotions (but this simplification is on the verge of vulgarity). Well, one more important note: intelligence is a collective concept, and many cognitive functions that are most likely part of IQ are subject to their own age dynamics. I already wrote about working memory, but, for example, vocabulary and some elements of verbal intelligence reach their peak after forty. Therefore, it is difficult to talk about the smartest age, but even if you put the question like this, then 14 years is probably not the right answer.
