Common/uncommon names related with crime

I read this article on FOX News about how boys that have a more common name like Michael are less likely to commin a crime than boys with the name of Ivan. Their studies show that the PNI (popularity name index) for Michael is 100 which is the most frequently given name and Malcolm has the PNI of 1. Regardless of race the boys with the least popular names are more likely to commit a crime. The least popular names were associated with juvenile deliquency among black and whites. They say kids with uncommon names are usually treated differently by peers which makes it harder to form relationships. Good thing i have a commmon name.
