What scientists think of the trending "right brain/left brain" tests?

Do you want to know which side of your brain, left or right, is more dominant and by how much? American neuropsychologist Roger Sperry won the 1981 Nobel Prize in Physiology and Medicine for his work in split-brain research.
Take this test to get the most accurate results.
Answer these 31 questions prepared by psychologists to see if you are more left brain oriented or right brain oriented. The test is free and no need to register!

There are different versions - several have been shared hundreds of thousands of times on Facebook - but most of them take the form of a quiz which purports to show how "left-brained" or "right-brained" you are. The idea is that the left side of the brain is associated more with logic and rationality and the right side controls creativity and emotion.
So is there any evidence that the two sides of the brain correspond to those particular characteristics?
"It is certainly the case that some people have more methodical, logical cognitive styles, and others more uninhibited, spontaneous styles," says Jeffrey Anderson, a brain researcher at the University of Utah. "This has nothing to do on any level with the different functions of the [brain's] left and right hemisphere."
Anderson led a team that looked at the brains of more than a thousand people and measured strong connections on both sides of the brain. They found that these connections were distributed fairly evenly - in other words, it wasn't the case that some people had stronger connections on one side of the brain or the other.
