Whenever the subject of Islamist terrorism comes up, the national conversation almost always circles back to a somewhat bigoted question: are Muslims more violent than other kinds of people because of their religion?

What these conversations usually lack is data; that is, evidence that Muslim societies are actually more violent than other ones. And it turns out, according to UC-Berkeley Professor M. Steven Fish, that judging by murder rates, people in Muslim-majority countries actually tend to be significantly less violent (bolding is mine):

Predominantly, Muslim countries average 2.4 murders per annum per 100,000 people, compared to 7.5 in non-Muslim countries. The percentage of the society that is made up of Muslims is an extraordinarily good predictor of a country's murder rate. More authoritarianism in Muslim countries does not account for the difference. I have found that controlling for political regime in statistical analysis does not change the findings. More Muslims, less homicide.
