Problematic research on oxytocin: If the study design excludes women, its findings cannot include women

This 2014 study’s findings that “the hormone oxytocin promotes group-serving dishonesty” can’t apply generally to humans because its subjects were ALL men.

Regarding oxytocin, the researchers certainly knew or should have known previous studies’ findings about sex differences, as did Is oxytocin why more women than men like horror movies? which cited:

“Oxytocin modulates brain activity differently in male and female subjects.”

Regarding differing reciprocal behaviors, the researchers also knew or should have been better informed about associated brain areas through studies such as Reciprocity behaviors differ as to whether we seek cerebral vs. limbic system rewards and its references.

And how could the study produce reliable, replicable evidence of:

Dishonesty to be plastic and rooted in evolved neurobiological circuitries”

when the researchers performed NO measurements of “neurobiological circuitries” that supported that finding?

What was the agenda in play here? What did the female Princeton reviewer see in this study that advanced science?
