Unconscious Bias: Possibly Preventable?

Today in class, the question came up whether we are responsible for the biases we hold and the stereotypes we have about people.  In many cases, these things are unconscious or subconscious.  This might seem to create a problem for whether we can prevent these attitudes. 

Here is a link to the Harvard Implicit Association Tests.  These tests are meant to measure what you unconscious, or implicit, biases are.  By definition, an implicit bias is a bias you have that you are not even aware of.  We might think that acknowledging our own biases is necessary in order to prevent those biases.  Test yourself and see what biases you haven't prevented yourself from acquiring!
