I agree with midnight even though she didn't really touch on why men lie. Which leads me to Project's comments.
"What the article was discussing was biological gender imperatives to lie."
Like midnight pointed out, gender is a creation by society, not biology. And the language we created and speak do reflect our gender biases. Then again would one change the word manhole to personhole?
Going back, to say "biological gender" is at least a little bizzarre. I assume the article explores the motives of lying based on sex but clearly one cannot escape the conventions of society in creating biases.
