 from these same Interpol yearbooks while including all 4 years (1983 to 1986). Results: We found significant differences between Caucasoids and Negroids on all variables except for serious assault, but all of these significant trends except for homicide were in the direction opposite to the one claimed by Rushton: the Caucasoids had higher crime rates. Thus, point biserial correlation coefficients indicated that reported crime rates for Negroids were significantly lower than those of Caucasoids with respect to sex offenses with rape included (-.77, p<.001), rape data calculated separately (-.63, p<.001), theft (-.69, p<.001), and robbery and violent theft (-.38, p=.006). Only the reported homicide rates were slightly higher for blacks (.43, p. 001), in those 4 years. Discussion: Our reason for re-analysing the data for all 4 years was only to examine if a selection bias was present: we ourselves do not accept such official crime data without great scepticism. Rushton’s arbitrary exclusion of data that are strongly non-supportive of his racial theory is indeed suspect and seems consistent with his prior fraudulent attempt to disguise a reference to Penthouse as a reference to a truly scientific article.&picture=http://www.aascit.org/aascit/decorators/img/journal/929.jpg)

Background and Objective: In 1990, J. P. Rushton published his analyses of crime data from Interpol handbooks for 1983-84 and 1985-86, but without explanation, included only the years 1984 and 1986. He reported that countries with predominantly Negroid population had significantly higher crime rates than predominantly Caucasoid or Mongoloid countries. The present article examines if Rushton selected only confirmatory data. Materials and Method: We re-calculated ANOVA on crime rates (rates of homicide, serious assault, sex offenses, rape, theft, robbery and violent theft) from these same Interpol yearbooks while including all 4 years (1983 to 1986). Results: We found significant differences between Caucasoids and Negroids on all variables except for serious assault, but all of these significant trends except for homicide were in the direction opposite to the one claimed by Rushton: the Caucasoids had higher crime rates. Thus, point biserial correlation coefficients indicated that reported crime rates for Negroids were significantly lower than those of Caucasoids with respect to sex offenses with rape included (-.77, p<.001), rape data calculated separately (-.63, p<.001), theft (-.69, p<.001), and robbery and violent theft (-.38, p=.006). Only the reported homicide rates were slightly higher for blacks (.43, p. 001), in those 4 years. Discussion: Our reason for re-analysing the data for all 4 years was only to examine if a selection bias was present: we ourselves do not accept such official crime data without great scepticism. Rushton’s arbitrary exclusion of data that are strongly non-supportive of his racial theory is indeed suspect and seems consistent with his prior fraudulent attempt to disguise a reference to Penthouse as a reference to a truly scientific article.
