Regarding the question about research into why certain groups are less law abiding, I would not phrase the question in such terms. There is research into why some groups have better educational attainment, or a greater prevalence of criminal behaviour. As said, Chinese do well, Pakistanis not well, Indians well, so called poor whites do badly. Gypsies do the worst, with a massively disproportionate prison population, and perhaps not just because they are more likely to get caught, but due to very low educational attainment. And perhaps an acceptwnce of criminality as normal, although that remark will get the bleeding heart liberals wailing out loud. Cultural factors are surely the key reason. Nothing to do with genetics. Interestingly blacks do much better in the West Indies than here, if I recall correctly, with a much higher prevalence of schizophrenia here, due perhaps to the impact of racism i.e persecution does exist, and causes psychosis. Sad really.
