There are so many ways to be intelligent,

but a lot of careers they reward one type of intelligence above all others,

fluid intelligence.

Your fluid intelligence is your cognitive horsepower,

your creative capacity to analyze things quickly

and come to solutions, to come up with new ideas that nobody

never thought of before. That's Arthur Brooks. He's a social scientist and he

spent the last decade running a conservative think tank, the American Enterprise

Institute. New ideas have been his trade for a very long time,

which is honestly kind of a problem for him. You see, Arthur also believes that our fluid

intelligence begins to decline in our 30s and 40s as in my age

we can work harder and harder but our new ideas just won't seem as sharp. Arthur is 55

and so last summer he decided it was time to change careers

because while our fluid intelligence may decline, Arthur says we tend to develop

something else in the middle decades of our lives, crystallized intelligence.
