Because it leaves the human brain in a conflicting situation, facing two different stimuli.

Explanation:

The Stroop effect is a phenomenon that occurs when you must say the color of a word, but not the name of the word. For example, the word "blue" may be printed in red and you should say the color instead of the word.

The Stroop effect is a demonstration of the phenomenon that the reaction time of the brain decreases when it has to deal with conflicting information.  This delayed reaction time occurs due to interference or a processing delay caused by competing or incompatible functions in the brain.

The effect became widely known after John Ridley Stroop, an American psychologist, published an article in 1935, but was studied by several other researchers before Stroop.
