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.
"There is no such thing as the real mind. Ridding yourself of delusion: that's the real mind."
(Sheng-yen: Getting the Buddha Mind, p 73)
“Don’t rashly seek the true Buddha;
True Buddha can’t be found.
Does marvelous nature and spirit
Need tempering or refinement?
Mind is this mind carefree;
This face, the face at birth."
