I think with the Implicit association test I knew I had some bias but was surprised how strongly I associated Native American with foreign and that I do it somewhat with Asians as well. It may be because I have less experience with Native populations, but it is scary how even subconsciously these biases reflect reality. Also found slight bias toward light skinned over dark skinned and white over black. I know these are my own, but it was very hard taking the test to not make these automatic associations even when I deliberately tried not to. I think in addition to my own biases that in some ways society also pushes us to feel or associate things this way.
