Based on the article there are a few problems with the research.
“More masculine-looking men (were) rated as more probable to be unfaithful and having a sexual history of being more unfaithful.”
"Men, on the other hand, seemed to have no clue. They tended to perceive attractive, feminine women to be unfaithful, when there was no evidence that they were, the scientists noted."
So, if someone matches the stereotypical idea of man/woman it's more likely to be also unfaithful according to both sexes. And while men confessed their unfaithfulness to a greater extent, women did not, the reason being the social view of adultery that this article strengthens and follows.
"While teachers of the middle way, mind only, transcendent wisdom, mantra, and other schools may have their own assertions, the fulfillment of those intentions is the same. There is not a single thing that is not contained within mind."

“If you recognize the world of appearance and existence as the mind, realize the mind itself as empty, and have no grasping at the superiority of your realizations — this is the ultimate view."
