IQ tests really only look at a small side of how your brain works. They don't measure your emotional intelligence, social aptitude, or anything along those lines. Those things are just as important in being able to perform in life, especially when you are being expected to perform alongside (or with) other people such as in a workplace, a school, or within your own relationships.

Very often people who have a high traditional IQ will have social difficulties stemming from a low or underdeveloped emotional/social IQ. Tests that force us to think logically are absent all of the factors we have to maneuver through actual life with. They present us with very clear questions that have rational, logical solutions. That's not how we live though. We can try to think logically when it comes to real life, but emotions, hormones, and fears are a part of who we are, and they affect the decisions we make and how we see the world.

As an example, most people will say our world population is too high. They look at the water shortages, food shortages, habitat destruction, pollution, disease, wars, and overfishing and come to the rational conclusion that if there were fewer people, those problems would be lessened.

However, when most people decide to be a parent they choose to have their own biological child, rather than adopt. Logically it would make more sense to adopt. It's raising child who is already alive and who needs parents, versus adding another child to world and leaving an already living child in the foster system. That decision is being influenced by hormones and emotions though. It doesn't matter how smart someone is IQ-wise, chances are every individual alive will at one point in their life experience the desire to have their own biological child. So long as a person has hormones and emotions they will not be able to only think rationally.

What I'm trying to get at here is don't beat yourself up when you do something dumb. Your decisions are influenced by more than just your traditional IQ, so even if you have a high IQ that will never ensure all your decisions will be good ones. You've got to grant yourself some leeway for your weaker areas to make mistakes
