So, I went to this one website
http://www.yourmorals.org and took some test. One was on differentiating the shades of grey. This is what they say about the test after you take it:
In this task, you were asked to identify the shade of gray in which various words appeared. There were immoral words (e.g., sin), moral words (e.g., angel) and neutral words (e.g., aspect). We predict that certain words will appear slightly darker, and others slightly lighter, depending upon the moral connotation of the word. ... Your score indicates the average number of shades off you were from the actual shade. A score of zero means you estimated correctly, positive scores mean you tended to think the words were darker than they really were, and negative scores mean you tended to think the words were lighter than they really were.
Yeah, not so much for me. I scored a positive 15.6 for moral words, positive 11.1 for immoral words and positive 16.6 for neutral words.
I hope I didn't screw up their study.
