The graph shows that Mexican Americans are more likely than any other large ethnic group to say one should always obey the law. I'm not sure that this is the best attitude, but Mex-Ams clearly stand out. Blacks and American Indians (on the right end of the chart) are also above average; it looks like higher IQ groups have less absolutist attitudes.I checked by cross-tabulating this question with IQ (WORDSUM). Wow, smart people respect the following of one's conscience.
I guess my first attempt to find a pro-Mex-Am stat didn't quite work out.
