Pfeiffer said that even when other social factors were taken into account, there remained a significant correlation between religiosity and readiness to use violence. There were some positive correlations too he said, noting that young religious Muslims were much less likely than their non-Muslim counterparts to drink alcohol – or to steal from shops.
The increased likelihood to use violence was restricted to Muslim boys Pfeiffer said – Muslim girls were just as likely to be violent as non-Muslim girls.
The results showed that Muslim boys from immigrant families were more than twice as likely to agree with macho statements than boys from Christian immigrant families. The rate was highest among those considered as very religious, Pfeiffer said. They were also more likely to be using violent computer games and have criminal friends.
TheI selected quotes above from the article gave factual information about the study. Much of what I edited out were the efforts of the researcher to report his results without being labeled a bigot.
