Wondering what being 'smart' means? Is it:

1. being right most of the time?

2. knowing a lot (breadth)?

3. knowing a couple things in depth?

4. knowing in breadth and depth?

5. understanding new things fast (which is only measurable by someone who knows more?)?

6. solving puzzle and brainteasers easily?

7. being able to speak multiple languages?

8. being self-taught in what people may claim to be complex subjects?

9. being able to derive truths that other people fail to see?

10. being less prone to cognitive biases?

11. Mental clarity and easier data acquisition and processing?

Or something else?
