A Michigan State University study published in the Archives of General Psychiatry suggests that married men behave better , meaning they are less aggressive and less likely to break the law . The authors suggest that the cause is twofold: on the one hand , marriage inhibits antisocial behavior , but also less antisocial men are more likely to marry.
To reach this conclusion, the scientists, led by geneticist Alexandra Burt, examined 289 sets of male twins at different times in their lives. The study revealed that those with the lowest levels of antisocial behavior at 17 and 20 were more likely to have been married at 29. And that, after going through the altar, the rates of antisocial behavior dropped considerably, something that was especially evident when in a pair of identical twins, one married and the other remained single.
