IQ is not super useful in my opinion. It may be an indicator of problem solving ability to an extent. But there are lots of different types of intelligence - musical, mechanical, great fishermen, etc. When I taught many years ago, after a while I looked at people kind of as entities with multifaceted personalities/abilities/talents/ etc. Some had facets and sides of irregular proportions and were better at some thing than others. In a group of people, there is usually someone that can solve any certain problem or achieve things you wouldn't consider. I hope that made sense.
