There are a lot of different types of personality tests, some more scientific than others.
While many are very concise, like the Meyers-Briggs personality test, the hallmark of a good online personality test is that it's fun to take!
One of my favorite types of personality tests are based optical illusions. An optical illusion is an illusion caused by crossed wires in your brain.
Information is gathered by the eye and processed by the brain, but optical illusions can often be very different than how our brains initially perceive them.
There are three types of optical illusion: literal optical illusions that create images different from the objects that make them, cognitive illusions, which are the result of unconscious inferences, and physiological illusions, caused by excessive stimulation of some type or another.
Each one of the illusions below will employ a different type of optical illusion, and the results, namely what you see first, will shed some light on the way your brain thinks and your personality works.
