Wives do beat their husbands, I'll grant you that. But I'm going to want to see one hell of an impressive citation before I believe that they are "just as likely to beat their husbands".

Not that I'm agreeing with the grandparent comment, but this is a pretty great paper discussing that.

They're not just as likely to beat their husbands, but violence against children appears to be 50-50; family violence vs. intimate partner violence, basically.

That appears to be a study from Australia. Not exactly a country well known for arranged marriages.

In Bangladesh where I’m from (a “moderate” country) 80-90% of women are victims of domestic violence. The women do not hit back; that would get them killed.

Physical violence is more likely to be done by husband - by factor 10:1. Verbal abuse is less unequally distributed.

The rates of both depend on a lot of factors like culture, employment rates of males, employment rates of women, etc.
