Are you interested in testing exploring the beliefs, attitudes and assumptions that you may be unwilling to admit to others?
If so, take The Implicit Association Test. In many cases it will reveal an attitude that you didn't realise you had eg you may state that you believe that women and men should be equally associated with science, but you might automatically associate men with science more often than you do women. The test can reveal thoughts and feelings that are outside your conscious awareness and control, and reveal hidden biases and prejudices. Fascinating stuff!
