I only put it up for a bit of fun, but let me tell you what the author of blink experienced.
You cannot cheat the test. The test simply measures the amount of time you take to answer the questions. And then puts different sets of questions. It is the difference in the amount of time taken, that indicates the way your unconscious mind is working. Out of 50,000 black Americans, 50% were found to have at least a pro-white mild bias, this included the author whose mother was Jamaican. this was no shock. How could black Americans living in a society where the dominant group shape the culture, and present the dominant group as the best, not effect black American consciousness? However, the bias could be effected.
The author of the test used to take the test every day. And he found one morning he had a pro-black American bias, the first time ever. The guy was a track and field fan, and had been watching the Olympic Games. He then went on to do further tests, which showed if you give people positive black role models before the test, for example reading about Martin Luther King Nelson Mandela etc, you could effect the score.
this shows how the unconscious mind actually behaves much like computer, garbage in garbage out, rather than the value loaded decision-making tool we have always considered it to be.
