The person who edited the Wikipedia article on the Duluth Model actually knows what they're talking about

The article calls the Duluth Model out for being pseudoscientific, rejecting female-to-male, same-sex, and bidirectional domestic violence and abuse, for being an extreme, simplistic, black-and-white, negative, polarized, discriminatory, and polarized model, and not being created through academic study.

The article also points out that the creators were "finding what [they] had already predetermined to find."
