How Quick Thinking Is Related to High Intelligence

It is because speed is one characteristic of high intelligence.

Here are the other characteristics of high intelligence and quick thinking:

Admit to what they don’t know quickly

I think a common trap that many people fall under is trying to pretend we understand something that we don’t know while nodding our heads meaninglessly. We do this because we don’t want to appear uninformed and unknowing. (I’m still working to improve on this myself)

I think intelligent people get straight to the point. They say “I don’t understand this, can you explain it to me like I’m 5?”

They couldn’t care less about what others perceive their understanding or intelligence to be. What they do care about is catching up and learning so that they can understand in the first place.

They know that without a solid understanding of the basics, there’s no hope for them to grasp the more complex material.

Consider different points of view

Truly intelligent people have the ability to inhabit a different perspective, especially a perspective they disagree with. Abraham Lincoln would sometimes argue with a friend from one perspective, and then they would switch and argue from the opposite perspective.
