How to identify people's intelligence ?

Education:
IQ is no longer the only indicator to identify a person's intelligence.

There are at least 8 intelligences from the book "Intelligence" by Linda Wasmer Andrews, who examines various theories and types of intelligence with historical data for people who have made significant contributions to the field, i.e.,

- Linguistic intelligence ("word smart")

- Logical-mathematical intelligence ("number/reasoning smart")

- Spatial intelligence ("picture smart")

- Bodily-Kinesthetic intelligence ("body smart")

- Musical intelligence ("music smart")

- Interpersonal intelligence ("people smart")

- Intrapersonal intelligence ("self smart")

- Naturalist intelligence ("nature smart")

Robert, thanks for your question. I wanted to educate myself along with other global parents and youths since I am father of two boys. Besides IQ, what should we explore ?
