emLiveScience/em reports:br /br /blockquoteBoys in the United States with common names like Michael and David are less likely to commit crimes than those named Ernest or Ivan. br /br /David E. Kalist and Daniel Y. Lee of Shippensburg University in Pennsylvania compared the first names of male juvenile delinquents to the first names of male juveniles in the population. The researchers constructed a popularity-name index (PNI) for each name. For example, the PNI for Michael is 100, the most frequently given name during the period. The PNI for David is 50, a name given half as frequently as Michael. The PNI is approximately 1 for names such as Alec, Ernest, Ivan, Kareem, and Malcolm. br /br /Results show that, regardless of race, juveniles with unpopular names are more likely to engage in criminal activity. The least popular names were associated with juvenile delinquency among both blacks and whites. br /br /The findings, announced today, are detailed in the journal Social Science Quarterly. br /br /While the names are likely not the cause of crime, the researchers argue that “they are connected to factors that increase the tendency to commit crime, such as a disadvantaged home environment, residence in a county with low socioeconomic status, and households run by one parent.” /blockquotebr /br /I once knew a caseworker who had two kids named Rotunda and Vagina on her caseload. I often wonder how those kids turned out.
