After reading items like http://www.washingtonpost.com/wp-dyn/content/article/2007/05/02/AR2007050202304.html?hpid=topnews and http://www.freakonomics.com/blog/2007/05/02/racial-bias-in-nba-refereeing/, I drifted to
https://implicit.harvard.edu/implicit/ and
https://implicit.harvard.edu/implicit/india/selectatest.jsp
and took the Caste IAT. Apparently, I prefer scheduled castes to forward castes.
