When I started the first IAT (Skin Tone) it felt horrible to associate negative terms to darker skin tones. I actually felt like not completing the test. But I pushed on when I realized that the test was trying to create a bias within me, which made me feel manipulated. Then, I just assessed the images and words based on the criteria and completed the test. Which I did for all the remaining tests as well.
I have not grown up in America. I believe it is for this reason I didn't have any bias.
