According to some psychologists, intelligence is the ability to learn from experience,
adapt to new situations, understand and handle abstract concepts, and use knowledge to change one's environment.
Skills like learning, memory, reasoning, and problem solving enhance these abilities.
Therefore, certain habits may be evidence you've got these skills.
For example, it is commonly thought that those who are intelligent are organized and have everything in their workspace arranged neatly.
But that's not the case.
In an experiment from the University of Minnesota, people in a messy setting came up with more creative ideas than those in a neat space.
Kathleen Watts, study author says disorderly environments seem to inspire breaking free of tradition, which can produce the fresh idea.
Orderly environments, in contrast, encourage following traditions and playing it safe.
But according to JonathanWhite, a research scientist at Duke University, creativity is one of the qualities that smarter people tend to possess, and it may actually lead to messiness.
He says it's not messiness that helps creativity, but creativity which may create messiness.
Such people tend to get lost in thought while focusing on a problem or issue.
And cleanliness becomes of less importance that focusing on the problem at hand.
