The "sociopath" reference or association is incorrect for this test.
This tests points out that you have two parts of the brain. One which is your analytical part which as in the test above solves math equations and such and the 2nd part of your brain is the "creative," side.
All the results point out is that the analytical part dulls your creative side IF you were to say 1.) red, 2.blue 3. yellow and 1. hammer, 2. wrench, 3. screwdriver.
Why these three colors? They are primary colors and are what we are used to seeing, Red = stop blue = water/sky and yellow = sun. The 3 tools are the most common item you would find in a tool box.
So point is, If you were to have said let's say mauve saw instead, that would point out you are more creative than others who are more wired into responding with red,blue,yellow and hammer, wrench or screwdriver.
Notice the question wasn't your "favorite color or tool ," rather what first comes to mind, This is known as associative thinking process which shows it is dulled when the analytical part of the brain takes over dulling our creative side.
