Thanks for clarifying.
I know the articles and know how they do it. (mostly nuclear brain scan and blood flow study or anatomic/physical differences )
The results could be variable and some results were actually refuted by other researches.
To make the long story short:
These differences cannot prove women are either smarter 
or they have better abilities for future planning.
Some ways women are better and other ways men are. This is the take home message.
For future planning, both are needed.
BUT!
Women brain is smaller…and women talk more…
