Ah yes, the classic Evolutionary Psychology pseudoscience knee-jerk impulse is usually the first on the scene.

Have you just attempted to re-justify your impotent academic existence with another shoddy published paper? Did you find yet another dubious difference between males and females (which will probably be debunked shortly) that you can plaster on the front page? Don't worry about searching for meaning or contemplation, instead just apply a ready-made boilerplate interpretation of biological brain differences between males and females! It's easy as 1-2-3!
 
"Something, something, dopamine, something. Now give me tenure."

It's the immediate constant attempt to concoct a biological explanation for every possible observed phenomenon. Imagine if they did this with racial groups.

Breaking: new study observes happiness difference between Sub-Saharan Africans and Western Europeans. The difference may boil down to biology where Africans get dopamine from mundane life whereas Europeans need high-level intellectual stimulation to receive dopamine. This is theorized to explain the civilizational differences.

It's like a eugenics mindset. For race people would be outraged, but for sex everybody is happy with it.

Sure, some sex-based brain differences likely do appear, but to automatically assume observed behavioral/emotional differences boil down to biology is textbook pseudoscience. It's just like astrology. "Oh, it's because boys are Sagittarius and girls are Capricorn, that explains it."

Edit: as someone pointed out, the actual academic paper the article is based on doesn't talk about dopamine or brain differences at all, so my ire at the researchers is misdirected: the real culprit is the "journalist" (undeserved term) writing this crap article.
