Yes, it is true that there are left-brain dominant and right-brain dominant people. But except for a very few, most people are not that extreme one way or the other. Those that are extremely one way or the other usually have a difficult time in everyday life, although they may be extremely gifted in a single area.

And although one side of the brain does control certain functions, it is not as simple as if you are left-brain dominant, you will act one way or excel in a certain function set, and if right-brain dominant, another. First of all, one side is usually only slightly more dominant than the other, and traits within one side of the brain may be stronger in one individual than another.

Also you can have very strong traits from both sides of your brain. And even have one trait that is specifically a right-brain function, that is extremely strong, but be primarily left-brain dominant in every other way.

Science has a long way to go yet before they fully understand the workings of the human brain. At best these tests can only be a guide, and at worst, mean nothing at all.
